Corneal Surgery, Laser: Surgical techniques on the CORNEA employing LASERS, especially for reshaping the CORNEA to correct REFRACTIVE ERRORS.Refractive Surgical Procedures: Surgical procedures employed to correct REFRACTIVE ERRORS such as MYOPIA; HYPEROPIA; or ASTIGMATISM. These may involve altering the curvature of the CORNEA; removal or replacement of the CRYSTALLINE LENS; or modification of the SCLERA to change the axial length of the eye.Lasers, Excimer: Gas lasers with excited dimers (i.e., excimers) as the active medium. The most commonly used are rare gas monohalides (e.g., argon fluoride, xenon chloride). Their principal emission wavelengths are in the ultraviolet range and depend on the monohalide used (e.g., 193 nm for ArF, 308 nm for Xe Cl). These lasers are operated in pulsed and Q-switched modes and used in photoablative decomposition involving actual removal of tissue. (UMDNS, 2005)Cornea: The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)Lasers: An optical source that emits photons in a coherent beam. Light Amplification by Stimulated Emission of Radiation (LASER) is brought about using devices that transform light of varying frequencies into a single intense, nearly nondivergent beam of monochromatic radiation. Lasers operate in the infrared, visible, ultraviolet, or X-ray regions of the spectrum.Lasers, Solid-State: Lasers which use a solid, as opposed to a liquid or gas, as the lasing medium. Common materials used are crystals, such as YAG (YTTRIUM aluminum garnet); alexandrite; and CORUNDUM, doped with a rare earth element such as a NEODYMIUM; ERBIUM; or HOLMIUM. The output is sometimes additionally modified by addition of non-linear optical materials such as potassium titanyl phosphate crystal, which for example is used with neodymium YAG lasers to convert the output light to the visible range.Laser Coagulation: The use of green light-producing LASERS to stop bleeding. The green light is selectively absorbed by HEMOGLOBIN, thus triggering BLOOD COAGULATION.Laser Therapy, Low-Level: Treatment using irradiation with LASER light of low power intensity so that the effects are not due to heat, as they are in LASER THERAPY.Bowman Membrane: A layer of acellular matrix that lies beneath the CORNEAL EPITHELIUM and above the CORNEAL STROMA. It consists of randomly arranged COLLAGEN fibers in a condensed bed of intercellular substance. It provides stability and strength to the cornea.Descemet Membrane: A layer of the cornea. It is the basal lamina of the CORNEAL ENDOTHELIUM (from which it is secreted) separating it from the CORNEAL STROMA. It is a homogeneous structure composed of fine collagenous filaments, and slowly increases in thickness with age.Corneal Transplantation: Partial or total replacement of the CORNEA from one human or animal to another.Keratomileusis, Laser In Situ: A surgical procedure to correct MYOPIA by CORNEAL STROMA subtraction. It involves the use of a microkeratome to make a lamellar dissection of the CORNEA creating a flap with intact CORNEAL EPITHELIUM. After the flap is lifted, the underlying midstroma is reshaped with an EXCIMER LASER and the flap is returned to its original position.Keratoplasty, Penetrating: Partial or total replacement of all layers of a central portion of the cornea.Corneal Stroma: The lamellated connective tissue constituting the thickest layer of the cornea between the Bowman and Descemet membranes.Photorefractive Keratectomy: A type of refractive surgery of the CORNEA to correct MYOPIA and ASTIGMATISM. An EXCIMER LASER is used directly on the surface of the EYE to remove some of the CORNEAL EPITHELIUM thus reshaping the anterior curvature of the cornea.Corneal Endothelial Cell Loss: Loss of CORNEAL ENDOTHELIUM usually following intraocular surgery (e.g., cataract surgery) or due to FUCHS' ENDOTHELIAL DYSTROPHY; ANGLE-CLOSURE GLAUCOMA; IRITIS; or aging.Endothelium, Corneal: Single layer of large flattened cells covering the surface of the cornea.Myopia: A refractive error in which rays of light entering the EYE parallel to the optic axis are brought to a focus in front of the RETINA when accommodation (ACCOMMODATION, OCULAR) is relaxed. This results from an overly curved CORNEA or from the eyeball being too long from front to back. It is also called nearsightedness.Descemet Stripping Endothelial Keratoplasty: A surgical procedure or KERATOPLASTY involving selective stripping and replacement of diseased host DESCEMET MEMBRANE and CORNEAL ENDOTHELIUM with a suitable and healthy donor posterior lamella. The advantage to this procedure is that the normal corneal surface of the recipient is retained, thereby avoiding corneal surface incisions and sutures.Corneal Diseases: Diseases of the cornea.Compressed Air: Air that is reduced in volume by pressure.Oxygen Inhalation Therapy: Inhalation of oxygen aimed at restoring toward normal any pathophysiologic alterations of gas exchange in the cardiopulmonary system, as by the use of a respirator, nasal catheter, tent, chamber, or mask. (From Dorland, 27th ed & Stedman, 25th ed)Medical Waste Disposal: Management, removal, and elimination of biologic, infectious, pathologic, and dental waste. The concept includes blood, mucus, tissue removed at surgery or autopsy, soiled surgical dressings, and other materials requiring special control and handling. Disposal may take place where the waste is generated or elsewhere.Aviation: Design, development, manufacture, and operation of heavier-than-air AIRCRAFT.Cosmic Radiation: High-energy radiation or particles from extraterrestrial space that strike the earth, its atmosphere, or spacecraft and may create secondary radiation as a result of collisions with the atmosphere or spacecraft.Aerospace Medicine: That branch of medicine dealing with the studies and effects of flight through the atmosphere or in space upon the human body and with the prevention or cure of physiological or psychological malfunctions arising from these effects. (from NASA Thesaurus)Aircraft: A weight-carrying structure for navigation of the air that is supported either by its own buoyancy or by the dynamic action of the air against its surfaces. (Webster, 1973)Surgical Flaps: Tongues of skin and subcutaneous tissue, sometimes including muscle, cut away from the underlying parts but often still attached at one end. They retain their own microvasculature which is also transferred to the new site. They are often used in plastic surgery for filling a defect in a neighboring region.Patents as Topic: Exclusive legal rights or privileges applied to inventions, plants, etc.Corneal Topography: The measurement of curvature and shape of the anterior surface of the cornea using techniques such as keratometry, keratoscopy, photokeratoscopy, profile photography, computer-assisted image processing and videokeratography. This measurement is often applied in the fitting of contact lenses and in diagnosing corneal diseases or corneal changes including keratoconus, which occur after keratotomy and keratoplasty.Laser Therapy: The use of photothermal effects of LASERS to coagulate, incise, vaporize, resect, dissect, or resurface tissue.Lens, Crystalline: A transparent, biconvex structure of the EYE, enclosed in a capsule and situated behind the IRIS and in front of the vitreous humor (VITREOUS BODY). It is slightly overlapped at its margin by the ciliary processes. Adaptation by the CILIARY BODY is crucial for OCULAR ACCOMMODATION.Postoperative Period: The period following a surgical operation.Ultraviolet Rays: That portion of the electromagnetic spectrum immediately below the visible range and extending into the x-ray frequencies. The longer wavelengths (near-UV or biotic or vital rays) are necessary for the endogenous synthesis of vitamin D and are also called antirachitic rays; the shorter, ionizing wavelengths (far-UV or abiotic or extravital rays) are viricidal, bactericidal, mutagenic, and carcinogenic and are used as disinfectants.International Cooperation: The interaction of persons or groups of persons representing various nations in the pursuit of a common goal or interest.Consumer Satisfaction: Customer satisfaction or dissatisfaction with a benefit or service received.Blood Volume: Volume of circulating BLOOD. It is the sum of the PLASMA VOLUME and ERYTHROCYTE VOLUME.RestaurantsTime Factors: Elements of limited time intervals, contributing to particular results or situations.Corneal Opacity: Disorder occurring in the central or peripheral area of the cornea.

The repeating structure of each disaccharide involves alternate 1,4- and 1,3-linkages consisting of either N-acetylglucosamine or N-acetylgalactosamine.Immunologic Memory: The altered state of immunologic responsiveness resulting from initial contact with antigen, which enables the individual to produce antibodies more rapidly and in greater quantity in response to secondary antigenic stimulus.Antigens, Neoplasm: Proteins, glycoprotein, or lipoprotein moieties on surfaces of tumor cells that are usually identified by monoclonal antibodies. Many of these are of either embryonic or viral origin.Memory: Complex mental function having four distinct phases: (1) memorizing or learning, (2) retention, (3) recall, and (4) recognition. Clinically, it is usually subdivided into immediate, recent, and remote memory.Antibodies: Immunoglobulin molecules having a specific amino acid sequence by virtue of which they interact only with the ANTIGEN (or a very similar shape) that induced their synthesis in cells of the lymphoid series (especially PLASMA CELLS).Antigens: Substances that are recognized by the immune system and induce an immune reaction.Molecular Sequence Data: Descriptions of specific amino acid, carbohydrate, or nucleotide sequences which have appeared in the published literature and/or are deposited in and maintained by databanks such as GENBANK, European Molecular Biology Laboratory (EMBL), National Biomedical Research Foundation (NBRF), or other sequence repositories.Antibody Specificity: The property of antibodies which enables them to react with some ANTIGENIC DETERMINANTS and not with others. Specificity is dependent on chemical composition, physical forces, and molecular structure at the binding site.Keratoconus: A noninflammatory, usually bilateral protrusion of the cornea, the apex being displaced downward and nasally. It occurs most commonly in females at about puberty. The cause is unknown but hereditary factors may play a role. The -conus refers to the cone shape of the corneal protrusion. (From Dorland, 27th ed)Fuchs' Endothelial Dystrophy: Disorder caused by loss of endothelium of the central cornea. It is characterized by hyaline endothelial outgrowths on Descemet's membrane, epithelial blisters, reduced vision, and pain.Keratectomy, Subepithelial, Laser-Assisted: A surgical technique to correct REFRACTIVE ERRORS of the EYE, such as MYOPIA and ASTIGMATISM. In this method, a flap of CORNEAL EPITHELIUM is created by exposure of the area to dilute alcohol.

Stromal haze, myofibroblasts, and surface irregularity after PRK. (1/27)

The aim of this study was to investigate the relationship between the level of stromal surface irregularity after photorefractive keratectomy (PRK) and myofibroblast generation along with the development of corneal haze. Variable levels of stromal surface irregularity were generated in rabbit corneas by positioning a fine mesh screen in the path of excimer laser during ablation for a variable percentage of the terminal pulses of the treatment for myopia that does not otherwise generate significant opacity. Ninety-six rabbits were divided into eight groups: [see table in text]. Slit lamp analysis and haze grading were performed in all groups. Rabbits were sacrificed at 4 hr or 4 weeks after surgery and histochemical analysis was performed on corneas for apoptosis (TUNEL assay), myofibroblast marker alpha-smooth muscle actin (SMA), and integrin alpha4 to delineate the epithelial basement membrane. Slit-lamp grading revealed severe haze formation in corneas in groups IV and VI, with significantly less haze in groups II, III, and VII and insignificant haze compared with the unwounded control in groups I and V. Analysis of SMA staining at 4 weeks after surgery, the approximate peak of haze formation in rabbits, revealed low myofibroblast formation in group I (1.2+/-0.2 cells/400x field) and group V (1.8+/-0.4), with significantly more in groups II (3.5+/-1.8), III (6.8+/-1.6), VII (7.9+/-3.8), IV (12.4+/-4.2) and VI (14.6+/-5.1). The screened groups were significantly different from each other (p < 0.05), with myofibroblast generation increasing with higher surface irregularity in the -4.5 diopter PRK groups. The -9.0 diopter PRK group VI had significantly more myofibroblast generation than the -9.0 diopter PRK with PTK-smoothing group VII (p < 0.01). Areas of basement membrane disruption were demonstrated by staining corneas for integrin alpha4 and were prominent in corneas with grade I or higher haze. SMA-positive myofibroblasts tended to be present sub-adjacent to basement membrane defects. Late apoptosis was detected at 1 month after surgery within clusters of myofibroblasts in the sub-epithelial stroma. In conclusion, these results demonstrated a relationship between the level of corneal haze formation after PRK and the level of stromal surface irregularity. PTK-smoothing with methylcellulose was an effective method to reduce stromal surface irregularity and decreased both haze and associated myofibroblast density. We hypothesize that stromal surface irregularity after PRK for high myopia results in defective basement membrane regeneration and increased epithelium-derived TGFbeta signalling to the stroma that increases myofibroblast generation. Late apoptosis appears to have a role in the disappearance of myofibroblasts and haze over time.  (+info)

Treatment of an ocular squamous cell carcinoma in a stallion with atrial fibrillation. (2/27)

A stallion was presented for surgical treatment of limbal squamous cell carcinoma. Excision with a conjunctival pedicle flap was done to prevent ocular invasion and preserve vision. A complication was the diagnosis of atrial fibrillation, which was not converted to sinus rhythm due to the potential complication of treatment with quinidine sulfate.  (+info)

Biomechanics and wound healing in the cornea. (3/27)

The biomechanical and wound healing properties of the cornea undermine the predictability and stability of refractive surgery and contribute to discrepancies between attempted and achieved visual outcomes after LASIK, surface ablation and other keratorefractive procedures. Furthermore, patients predisposed to biomechanical failure or abnormal wound healing can experience serious complications such as keratectasia or clinically significant corneal haze, and more effective means for the identification of such patients prior to surgery are needed. In this review, we describe the cornea as a complex structural composite material with pronounced anisotropy and heterogeneity, summarize current understanding of major biomechanical and reparative pathways that contribute to the corneal response to laser vision correction, and review the role of these processes in ectasia, intraocular pressure measurement artifact, diffuse lamellar keratitis (DLK) and corneal haze. The current understanding of differences in the corneal response after photorefractive keratectomy (PRK), LASIK and femtosecond-assisted LASIK are reviewed. Surgical and disease models that integrate corneal geometric data, substructural anatomy, elastic and viscoelastic material properties and wound healing behavior have the potential to improve clinical outcomes and minimize complications but depend on the identification of preoperative predictors of biomechanical and wound healing responses in individual patients.  (+info)

Effect of refractive surgery on binocular vision and ocular alignment in patients with manifest or intermittent strabismus. (4/27)

OBJECTIVE: To evaluate the effect of refractive surgery on binocular vision and ocular alignment in patients with manifest or intermittent strabismus, with or without vertical component. SETTING: University Hospital Antwerp, Edegem, Belgium. PATIENTS AND METHODS: 13 patients (22 eyes) with strabismus underwent refractive surgery. Five of these patients presented with an esotropia and four of them with a small vertical deviation. Five patients had a manifest exotropia, of whom two presented with a small vertical deviation. Two patients had an intermittent exotropia with binocular vision, of whom one patient had a vertical deviation. One patient had a hypertropia with a dissociated vertical deviation. RESULTS: Ocular alignment and binocular function remained unchanged postoperatively in all except two patients with high anisometropia who experienced an improvement in binocular function. In these patients, the preoperative manifest deviation became intermittent or latent after surgery, allowing fusion and stereopsis. Vertical deviation was found preoperatively in 8 of the 13 patients. This vertical deviation remained unchanged postoperatively, but improved in one patient with anisometropia. CONCLUSION: Preoperative intermittent or manifest strabismus is not a contraindication for refractive surgery provided some specific recommendations are taken into account, such as an adequate preoperative orthoptic examination and aiming at emmetropia for both eyes.  (+info)

The variant N363S of glucocorticoid receptor in steroid-induced ocular hypertension in Hungarian patients treated with photorefractive keratectomy. (5/27)

PURPOSE: Variation in sensitivity to glucocorticoids observed in healthy population is influenced by genetic polymorphisms of the glucocorticoid receptor gene (NR3C1). N363S, ER22/23EK, and Bcl I have been previously described as glucocorticoid-sensitivity modulating polymorphisms. We investigated whether these variants may contribute to steroid-induced ocular hypertension and if they play a role as protective or risk factors during exogenous glucocorticoid administration. METHODS: We examined 102 patients who underwent photorefractive keratectomy and received topical steroids (either fluorometholone 0.1% or prednisolone acetate 0.5% alone or combined) as part of postoperative therapy. The choice of steroid depended on course of wound healing and regression. Variations in intraocular pressure (IOP) levels in response to steroid therapy were observed. To genotype DNA, allele-specific PCR amplification was applied for the N363S polymorphism, and PCR-based restriction fragment length polymorphism analysis was performed to examine the Bcl I and the ER22/23EK polymorphisms. We separately analyzed data from three groups of patients: those who received fluorometholone only; those who were initially given fluorometholone then later switched to prednisolone acetate; and those who received prednisolone acetate only. Covariance analysis with forward stepwise variable selection was carried out. RESULTS: In cases where prednisolone acetate was administered, we found a significant correlation between N363S heterozygosity and steroid-induced ocular hypertension. ER22/23EK and Bcl I polymorphisms do not have a major influence on the risk of developing steroid-induced ocular hypertension. CONCLUSIONS: Genotyping of high risk steroid responders may allow an individual therapy to avoid steroid-induced ocular hypertension. The N363S polymorphism may have a clinical significance in the future.  (+info)

Corneal molecular and cellular biology update for the refractive surgeon. (8/27)

PURPOSE: To review clinically relevant progress in understanding cellular and molecular interactions in the cornea that relate to refractive surgical outcomes in patients. METHODS: Recent published literature focused on femtosecond LASIK and surface ablation procedures, such as photorefractive keratectomy, was reviewed and correlated with clinical results of surgery. RESULTS: The femtosecond laser has a direct necrotic effect on stromal keratocytes, resulting in the release of cellular components that are chemotactic to bone marrow-derived inflammatory cells. Developments of the femtosecond laser led to lower energy delivery to the stroma and altered laser ablation profiles that decrease epithelial damage during the side-cut, and have markedly improved femtosecond LASIK to the point that the overall early postoperative healing response is indistinguishable from microkeratome LASIK. New studies have directly demonstrated the importance of surface irregularity and resulting structural and functional defects in the epithelial basement membrane, in the generation and persistence of anterior stromal myofibroblasts and haze following surface ablation procedures. These defects augment penetration of epithelium-derived TGF-beta, which is a critical modulator of myofibroblast development in the stroma. Studies on the mechanism of action of mitomycin C treatment to prevent haze have confirmed that the most powerful effect is on stromal cell proliferation and, therefore, decreased population of the anterior stroma with myofibroblast progenitor cells. An undesirable long-term effect of mitomycin C is diminished anterior stromal keratocyte density due to diminished keratocyte re-population. This raises concerns regarding future corneal anomalies in treated corneas. CONCLUSIONS: Basic research studies of refractive procedures provide important insights into the effects of wound healing on surgical outcomes.  (+info)

Surgical correction of refractive errors is becoming increasingly popular. In the 1990s, the excimer laser revolutionized the field of corneal refractive surgery with PRK and LASIK, and lately refractive lenticule extraction (ReLEx) of intracorneal tissue, using only a femtosecond laser, has become possible. Two new procedures were developed, ReLEx flex (FLEX) and ReLEx smile (SMILE). Until this thesis, only a few long-term studies of PRK with a relatively limited number of patients had been published; therefore, this thesis intended to retrospectively evaluate long-term outcomes after PRK for all degrees of myopia for a large number of patients. Furthermore, a prospective contralateral eye study comparing FLEX and SMILE, when treating high to moderate degrees of myopia, had not been performed prior to this study. This was the second aim of this thesis. In the first study, results from 160 PRK patients (289 eyes) were presented. Preoperative spherical equivalent ranged from -1.25 to -20.25D, ...
TY - JOUR. T1 - Laser vision correction in treating myopia. AU - Ehlke, Germano Leal. AU - Krueger, Ronald R.. PY - 2016/1/1. Y1 - 2016/1/1. N2 - Myopia is a generally benign refractive error with an increasing prevalence worldwide. It can be corrected temporarily with glasses and contact lenses and permanently with laser vision correction. The 2 main procedures currently being performed formyopia correction are photorefractive keratectomy and laser-assisted in situ keratomileusis. Each technique has its advantages, but they appear to yield similar visual outcomes 1 year after surgery. Laser vision correction for myopia was considered a paradigm shift because healthy eyes could now undergo a surgical procedure to permanently and safely correct the error by altering the center of the cornea, which was previously off limits because of the potential for loss of transparency. Customized ablation using wavefront aberrometry and its optimized profiles were created to correct higher-order aberrations ...
Laser vision correction is a refractive surgical procedure. Refractive surgical procedures include all of those which reduce refractive error, the inability of the eye to focus properly, due to discrepancies in eye anatomy. These surgical procedures would include the reduction of nearsightedness (myopia), farsightedness (hyperopia), and blurring due to astigmatism (caused by a cornea that is elongated rather than round). Laser vision correction is not ideally suited to correct for both distant and near vision, however, monovision is sometimes an option. With monovision, one eye is corrected for distance and the other for near. Although it sounds unusual, many people accommodate well and, in time, no longer notice that each eye perceives a different segment of their vision. Dr. Jason Steinfeld provides LASIK, LASEK, and PRK laser procedures for our practice. He offers evaluation at no charge to determine whether laser vision correction is right for you. Your evaluation will include an eye exam, ...
Scanning electron microscopy analysis demonstrated a few significant observations. First, a smooth corneal bed surface was observed in prelenticule-extracted (anterior lenticule surface) FLEx corneas, which were not discernibly different from those that underwent FS-LASIK. The surface quality of the anterior lenticule surface in our study for both FLEx and FS-LASIK were qualitatively comparable with a similar study by Kunert et al. 23 Second, we observed that the anterior lenticule surface was qualitatively smoother compared with the stromal bed, after the lenticule was removed at all myopic corrections. This rougher surface (mean irregularity scores, range, 8.7 to 10.3) was likely the result of the deeper plane of posterior cut and the trauma from manual removal of the lenticule as it is peeled from the stromal bed, 24 which emphasizes the need for gentle dissection. 25 Third, we compared the smoothness of the stromal beds at different treatment depths (mean depth: A, 189 ± 7.5 μm; B, 205 ± ...

Purpose: : To report the results of excimer laser vision corredtion in three patients with limbal stem cell insufficiency. Methods: : We reviewed the charts of three patients with limbal stem cell insufficiency that underwent laser vision correction because of contact lens intolerance. UCVA and BCVA, slit lamp findings, and corneal topography before and after excimer laser vision correction, were recorded. Results: : All patients were female with an average age of 38.3 years (range:33-43 years). One patient had Salzmanns nodules and another had contact lens warpage. Preoperative uncorrected visual acuity (UCVA) ranged from 20/60 to 20/400 and best corrected visual acuity (BCVA) ranged from 20/20 to 20/30. Three eyes underwent LASIK, two underwent LASEK and PTK/PRK was performed on the eye with Salzmanns nodule. Average postoperative follow-up was 10.4 months (4 months to 24 months). In five eyes, postoperative UCVA was the same as BCVA 20/20-20/25. In the sixth eye, a central stromal divot was ...
This type of laser vision correction does not require any corneal incision at all. A mild alcohol solution is placed on the corneal to loosen the top layer of tissue. Only the most superficial layer of the cornea is gently brushed aside. This thin flap is then replaced after the laser reshaping is complete. Less tissue is removed than with traditional Lasik. Patients with thin corneas, or patients who have had previous vision correction such as RK, can possibly now have laser vision correction safely performed. Healing may be faster than with traditional PRK ...
A method and system for reshaping Bowmans membrane, which lies directly below the anterior epithelial surface of the cornea, to provide correction of refractive errors in the eye by photoablation of selective regions of the Bowmans membrane without substantial penetration into the stroma of the eye is disclosed including a laser and a beam-shaping mask, disposed between the laser and the surface of the cornea, which imposes a defined ablation profile upon the Bowmans membrane by laser radiation. The system can also include a feedback control for measuring the effectiveness of the laser during operation and for controlling the laser such that the reprofiling operation is substantially confined to the Bowmans membrane throughout the procedure. The beam-shaping mask can include either an aperture e.g., a beam-shaping stop means alone or in combination with a beam-shaping window, or an mask which is erodible or otherwise graded in its absorptive capacity to present a predefined profile of resistance to

Laser-Assisted In Situ Keratomileusis (LASIK) is a flap surgery. A thin 22mm flap is created with a rapid and highly precise femtosecond laser. The flap is then gently folded back to expose the corneal surface for an excimer laser to reshape the cornea for vision correction. Visual recovery is quick and it is rare for patients to experience flap-related effects. LASIK is the most widely performed laser vision correction procedure since its introduction in the early 1990s. LASIK improves upon PRK in the areas of discomfort and recovery time, but may come with a higher possibility of dry eye. Here is the procedure:. ...
The aim of refractive corneal surgery is to modify the curvature of the cornea to improve its dioptric properties. With that goal, the surgeon has to define the appropriate values of the surgical parameters in order to get the best clinical results, i.e., laser and geometric parameters such as depth and location of the incision, for each specific patient. A biomechanical study before surgery is therefore very convenient to assess quantitatively the effect of each parameter on the optical outcome. A mechanical model of the human cornea is here proposed and implemented under a finite element context to simulate the effects of some usual surgical procedures, such as photorefractive keratectomy (PRK), and limbal relaxing incisions (LRI). This model considers a nonlinear anisotropic hyperelastic behavior of the cornea that strongly depends on the physiological collagen fibril distribution. We evaluate the effect of the incision variables on the change of curvature of the cornea to correct myopia and ...

There are possible risks with any surgical procedure. Serious complications with LASIK or PRK are extremely rare. The chance of having a vision-reducing complication from LASIK has been documented in clinical studies to be less than one percent. Many of the risks and complications associated with this procedure can be reduced or eliminated through careful patient selection and thorough pre-operative testing using the latest diagnostic technology.. After laser vision correction, you may experience some visual side effects. These are usually mild and most often diminish over a few days to a few weeks.

Figure 4c: Confocal image of a 44 y.o female who underwent LASIK OU 11 years previously. She suffers from intense symptoms of CCNP despite the absence of signs of axonopathy, nerve regeneration or inflammation, thus indicating the autonomy of CCNP.. Responsiveness to corneal anesthesia can sometimes be helpful in distinguishing between chronic peripheral and hard-wired centralized pain. Although incomplete or absent pain suppression support its central origin, total anesthetic suppression does not exclude this diagnosis since centralized corneal pain can be extinguished in some patients but only to lose this effect only to reoccur (personal observations). Increased mechanosensitivity of the bulbar conjunctiva (putatively, secondary hyperalgesia that precludes wearing scleral lenses), tactile allodynia of the skin and spontaneous pain that persists even in the presence of normal corneal nerve morphology (Fig.4c) indicate involvement of the central pain signaling circuitry independently of corneal ...
Cellular therapy of the corneal stroma, with either ocular or extraocular stem cells, has been gaining a lot of interest over the last decade. Multiple publications from different research groups are showing its potential benefits in relation to its capacity to improve or alleviate corneal scars, improve corneal transparency in metabolic diseases by enhancing the catabolism of the accumulated molecules, generate new organized collagen within the host stroma, and its immunosuppressive and immunomodulatory properties. Autologous extraocular stem cells do not require a healthy contralateral eye and they do not involve any ophthalmic procedures for their isolation. Mesenchymal stem cells have been the most widely assayed and have the best potential to differentiate into functional adult keratocytes in vivo and in vitro. While embryonic stem cells have been partially abandoned due to ethical implications, the discovery of the induced pluripotent stem cells (iPSC) has opened a new and very promising field for
Hi Scott, the surgery itself went well. However the Dr. put a small air bubble behind my layer of tissue in order to sandwich it up to the donor tissue and the air bubble was too big! The pain from the high press was unreal… immediately after the first surgery I was drifting in and out of consciousness and began to vomit. My core temperature was also fluctuating rapidly (sweating like crazy one second then freezing the next). The Dr. took me to an exam room and poked a needle in and removed the bubble and it was immediate relief. Along with a few flashing black vertical lines, this is basically what I saw before he took the air bubble out: http://teedhaze.com/images/public/tv-snow.gif. The next day (Tuesday) the Dr. examined me and said he needed to put the bubble back in immediately. The numbing drops didnt work at first so the pain was unreal when the needle went in.

The first observable phenomenon following a lesion of the corneal epithelium is the reduction in the number of keratocytes in the anterior stroma, just below the epithelial wound. The disappearance of keratocytes occurs via apoptosis.16 Apoptosis of keratocytes is mediated by the release of proapoptotic molecules by the damaged epithelium; it becomes evident within a few minutes after the onset of epithelial damage and proceeds for several hours.17 Several cytokines are involved in the induction of this process; among these, interleukin-1 (IL-1),17 Fas ligand,18 and tumour necrosis factor α (TNF-α)19 are the most important. The majority of these cytokines are constitutively produced by cells of the corneal epithelium which may release them immediately when they are damaged.. After the first phase of apoptosis, the surviving keratocytes, nearest to the area affected by the epithelial lesion, begin to proliferate. The cells undergo a process of metabolic activation, with increases in the size ...

Wound healing dressings are prepared by flocculating fibronectin, a biologically active fragment or an analog thereof to produce a water-swellable gel. The gels, in the form of sheets, strips, wedges, strands or I-shaped cross-sections, are especially useful in promoting the healing of corneal, scleral dermal, incisional wounds or lesions. They can be used to enhance the results obtained in keratorefractive surgeries and the healing scleral incision for intraocular surgery.

Progressive lenses eliminate image jump and create a more seamless progression throughout the lens. In doing so, the vision correction is more of a full range rather than separate sections within the same lens, giving you more comprehensive and effective vision quality, and making the vision correction feel more natural. All you will need to do is look up for distance vision, look down for reading or other close-up vision, and look straight ahead for vision that falls somewhere in the middle. Your eyes adjust to this much more naturally than the strict boundaries created in traditional bifocal lenses, making switching to progressive lenses much easier.. Progressive lenses can be customized to create the most beneficial vision correction for you. The experts at our Summerlin optical store would be happy to give you more personalized advice after an examination and consultation with Dr. Park. We can show you the various frames we have available that work with progressive lenses so that we can ...

Our practice is devoted to providing the highest standard of patient care. We have invested in this advanced technology to maintain that level of commitment. We use the IntraLase femtosecond laser to make the flap, thereby making LASIK an ALL-LASER procedure.. The IntraLase laser provides a less invasive, computer controlled approach to the important first step of the laser vision correction procedure. This step, traditionally performed with a surgical blade, has now been enhanced by the lasers micron level accuracy, making every procedure more predictable. This remarkable precision, provided by IntraLase technology, enables you to choose laser vision correction with confidence. By replacing the traditional approach with a silent, tiny beam of laser light, the IntraLase FS laser allows more patients to become candidates for laser vision correction due to this unique level of precision that was previously unavailable.. In seconds, with computer precision and high-speed delivery, the Intralase ...

Figure 4c: Confocal image of a 44 y.o female who underwent LASIK OU 11 years previously. She suffers from intense symptoms of CCNP despite the absence of signs of axonopathy, nerve regeneration or inflammation, thus indicating the autonomy of CCNP.. Responsiveness to corneal anesthesia can sometimes be helpful in distinguishing between chronic peripheral and hard-wired centralized pain. Although incomplete or absent pain suppression support its central origin, total anesthetic suppression does not exclude this diagnosis since centralized corneal pain can be extinguished in some patients but only to lose this effect only to reoccur (personal observations). Increased mechanosensitivity of the bulbar conjunctiva (putatively, secondary hyperalgesia that precludes wearing scleral lenses), tactile allodynia of the skin and spontaneous pain that persists even in the presence of normal corneal nerve morphology (Fig.4c) indicate involvement of the central pain signaling circuitry independently of corneal ...
A recent study compared the level of pain and discomfort as well as the epithelial healing rate of photorefractive keratectomy (PRK) and corneal collagen crosslinking (CXL), and found that the epithelial defect healing rate was faster in the CXL group, but the level of post-op pain was greater. The prospective clinical study was comprised of 68 patients: 34 in the PRK group and 34 in the CXL group. The PRK group included patients with simple refractive errors, whereas the CXL group included patients with clinical keratoconus. Both groups had bilateral same-day surgery. The groups were compared regarding the level of pain immediately and six hours after surgery and then one, three and seven days postoperatively. The epithelial defect size was measured at six hours after surgery and then one day and three days after surgery in both groups.. Researchers found the amount of pain was significantly higher after CXL than after PRK, although the epithelial defect size was significantly smaller in the ...
July 24, 2008 by · Leave a Comment On July 15 2007 Dr. Frank Polack, our colleague and friend, passed away. Frank was born and raised in Lima, Peru, and received his MD degree in 1954 from San Marcos University. After his graduation he emigrated to the United States, where he did his internship and began a residency in Neuropsychiatry at Grasslands Hospital, Valhalla, NY, a subsidiary of New York University Medical School. In 1956 he was married by proxy, his brother standing in for him, to his childhood sweetheart, Patricia Garcia, then Secretary to American Ambassador to Peru, who soon joined him in New York.. His contact with Dr. Ramon Castroviejo, the world-renowned pioneer in corneal surgery, had persuaded him to change his career choice to ophthalmology, and in 1957, he began his training at Grasslands under Dr. AG Gerry" Devoe, then Chair at NYU, who was also a pioneer in corneal surgery. On completion of his residency in 1960, he began an NIH Fellowship under Dr George Smelser at the ...

What is PRK?. PRK (Photorefractive Keratectomy) means removing (shaping) corneal tissue by light (laser) in order to achieve the desired refractive correction. PRK is the first laser vision correction treatment offered to spectacle/contact lens-dependent people. Newer patient-friendly laser techniques such as LASIK and LASEK pushed PRK to third place in the eyes of refractive surgeons.. What are the advantages of PRK?. One of the advantages of the PRK method is that it is an easy surgical procedure. Even a novice eye surgeon can accomplish a PRK operation after watching a few videotapes. But precise programming of the Excimer Laser for the desired vision requires years of experience, since every doctor's surgical method and the environmental factors require construction of special nomograms for specific prescriptions and age. Another advantage of PRK is its being a quick, painless and bloodless laser procedure. PRK consumes lesser corneal tissue than LASIK. PRK or LASEK become the obvious ...
If you have thin corneas and were told you were not a candidate for laser-assisted in situ keratomileusis, or LASIK (a corneal refractive procedure that requires the creation of a partial-thickness flap before the cornea is sculpted with a laser), PRK (Photorefractive Keratectomy) may be a good option for you ...
These imperfections in the focusing power of the eye are called refractive errors. There are three primary types of refractive errors: They are myopia, hyperopia and astigmatism. Persons with myopia, or nearsightedness, have more difficulty seeing distant objects as clearly as near objects. Persons with hyperopia, or farsightedness, have more difficulty seeing near objects as clearly as distant objects. Astigmatism is a distortion of the image on the retina caused by irregularities in the cornea or lens of the eye. Combinations of myopia and astigmatism or hyperopia and astigmatism are common ...

Aim: To determine the efficacy and safety of keratorefractive surgery in patients with accommodative and non-accommodative strabismus in a prospective study. Methods: Preoperative assessment included uncorrected (UCVA) and best corrected visual acuity (BCVA), manifest and cycloplegic refraction and orthoptic examination. LASIK, LASEK and Artisan phakic intraocular lens implantation were performed. All treated eyes had BCVA of at least 6/18 preoperatively. One year postoperatively, visual acuity, refractive error and ocular alignment were reassessed. Results: 28 patients (9 male, 19 female) of mean age 33.0±10.0 years (range 20 to 59). Esotropia was present in 16 patients; 9 fully accommodative, 3 partially accommodative and 4 non-accommodative. Twelve patients had exodeviations; 10 exotropia and 2 exophoria and history of strabismus surgery. Excellent visual and refractive outcomes were obtained postoperatively. There was no loss and one eye gained a line of BCVA. Fully accommodative esotropes ...
Optical ray tracing-guided myopic laser in situ keratomileusis: 1-year clinical outcomes Arthur B Cummings,1 Gabrielle E Kelly21Wellington Eye Clinic, Dublin, Ireland; 2School of Mathematical Sciences, University College Dublin, Dublin, IrelandPurpose: To compare the safety, efficacy, and predictability of laser in situ keratomileusis treatments at 1 year postprocedure using a novel geometric ray tracing algorithm with outcomes of treatments using wavefront-optimized, wavefront-guided, and topography-guided ablation profiles of an excimer laser (WaveLight GmbH, Erlangen, Germany; Alcon Laboratories, Fort Worth, TX, USA).Setting: Wellington Eye Clinic, Dublin, Ireland.Design: Retrospective comparative case series.Methods: Eyes having a preoperative myopic spherical equivalent refractive error >4.00 D and/or astigmatism between 2.00–6.00 D resulting in a spherical equivalent power greater than −4.00 D received laser in situ keratomileusis treatments using a ray tracing algorithm.

The refractive surgery team uses precision laser eye surgery techniques and specialised lens implants to correct focusing problems such as short sight (myopia), long sight (hypermetropia), irregular focus (astigmatism) and loss of reading vision (presbyopia). A refractive error, for example, partial blindness (near sightedness), farsightedness (hyperopia), astigmatism or presbyopia, refractive surgery is a strategy for revising or enhancing vision. There are different surgical methods for modifying eyes centering capacity by reshaping the cornea, or clear, round vault at the front of your eye. Different techniques include embedding a focal point inside the eye. The most generally performed kind of refractive surgery is LASIK (laser-aided situ keratomileusis), where a laser is utilized to reshape the cornea. For individuals who are myopic, certain refractive surgery systems will diminish the bend of a cornea that is excessively steep so that the eyes centering power is reduced. Pictures that ...
