Surgical techniques on the CORNEA employing LASERS, especially for reshaping the CORNEA to correct REFRACTIVE ERRORS.
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.
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)
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)
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 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.
The use of green light-producing LASERS to stop bleeding. The green light is selectively absorbed by HEMOGLOBIN, thus triggering BLOOD COAGULATION.
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.
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.
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.
Partial or total replacement of the CORNEA from one human or animal to another.
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.
Partial or total replacement of all layers of a central portion of the cornea.
The lamellated connective tissue constituting the thickest layer of the cornea between the Bowman and Descemet membranes.
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.
Loss of CORNEAL ENDOTHELIUM usually following intraocular surgery (e.g., cataract surgery) or due to FUCHS' ENDOTHELIAL DYSTROPHY; ANGLE-CLOSURE GLAUCOMA; IRITIS; or aging.
Single layer of large flattened cells covering the surface of the cornea.
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.
A surgical specialty concerned with the structure and function of the eye and the medical and surgical treatment of its defects and diseases.
Partial or complete opacity on or in the lens or capsule of one or both eyes, impairing vision or causing blindness. The many kinds of cataract are classified by their morphology (size, shape, location) or etiology (cause and time of occurrence). (Dorland, 27th ed)
The removal of a cataractous CRYSTALLINE LENS from the eye.
Surgery performed on the eye or any of its parts.
Surgery performed on an outpatient basis. It may be hospital-based or performed in an office or surgicenter.
A blocking of nerve conduction to a specific area by an injection of an anesthetic agent.
The organ of sight constituting a pair of globular organs made up of a three-layered roughly spherical structure specialized for receiving and responding to light.
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.
Diseases of the cornea.
A publication issued at stated, more or less regular, intervals.
Stratified squamous epithelium that covers the outer surface of the CORNEA. It is smooth and contains many free nerve endings.
Restoration of integrity to traumatized tissue.
Fibroblasts which occur in the CORNEAL STROMA.

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 ± ...

For individuals between ages 20 and 40 who are contemplating vision correction, we recommend LASIK or PRK. LASIK and PRK are both five-minute customized laser procedure where the surgeon selectively removes thin layers of tissue from the clear dome over the eye, the cornea. Both ...
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 ...

Eyeglasses and contact lenses are not the only ways to correct vision issues. Laser eye surgery can correct vision problems, bring back 20/20 vision and reduce or in most cases eliminate the need for contact lenses or glasses. Eye surgery is not for everyone, but you are considered a likely candidate for laser vision correction if you are over 21 years and your prescription hasnt changed over the past three years. You are also a good candidate if you have astigmatism, which is an oddly shaped cornea, or you are short or long-sighted.. Thanks to modern technology, approaches to the different laser eye surgery range from reshaping the curvature of the eyes clear front surface, known as the cornea in procedures such as LASIK and PRK to the surgical insertion of artificial lenses to refocus light rays to sharpen vision and correct a patients eyesight. You need a laser-specific eye exam to determine which of the following laser eye surgeries are ideal for your specific needs:. ...
A pair of multifocal contact lenses for a patient comprises a first corneal contact lens having a concave posterior surface and a convex anterior surface. The anterior surface is formed with a power curve including a circular intermediate vision correction zone and an annular distance vision correction zone contiguous with the intermediate vision correction zone. The distance vision correction zone is concentric or coaxial with the intermediate vision correction zone. A second corneal contact lens of the pair also a concave posterior surface and a convex anterior surface. The anterior surface of the second lens is formed with a power curve including a circular intermediate vision correction zone and an annular near vision correction zone contiguous with the respective intermediate vision correction zone. The near vision correction zone is concentric or coaxial with the intermediate vision correction zone of the second lens. The intermediate vision correction zone of the first lens and the distance

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 ...
In the above mentioned instances, it is recommended that you avoid corneal refractive surgery as the risk involved is greater than the benefit. If you use contact lenses, please discontinue their use for at least 2 weeks prior to the surgery. If you fulfill the above criteria and are interested in undergoing refractive surgery, discuss your decision with your corneal Refractive Surgeon. Your doctor may decide to perform an in-depth pre-procedural examination to evaluate the overall health of your eyes and determine your suitability for the procedure. ...

If left untreated, the cornea may thin to the point where a hole develops in the thinnest part. There is a risk of rejection after a cornea transplant, but the risk is much lower than with other organ transplants. You should not have laser vision correction (such as LASIK) if you have any degree of keratoconus. Corneal topography is done beforehand to rule out people with this condition. In rare cases, other laser vision correction procedures, such as PRK, may be safe for people with mild keratoconus. This may be more possible in people who have had corneal collagen cross-linking. ...
Epi-LASiK (Epithelial Laser In Situ Keratomileusis) is usually performed as an outpatient procedure using topical anesthesia with eyedrops. Your ophthalmologist (Eye M.D.) uses an alcohol solution to loosen and peel back the epithelium, the outermost layer of the cornea, to expose the corneal tissue beneath it. A cool excimer laser is used to permanently reshape the cornea, and the epithelium is either placed back into position, where it will selfadhere, or is removed completely, in which case the epithelium heals inward from the corneal periphery in just a few days ...
LASEK (Laser Assisted Sub-Epithelial Keratomileusis) is usually performed as an outpatient procedure using topical anesthesia with eyedrops.

NAPSI)-For those with vision correction needs, the daily rituals required in order to see clearly with glasses or contacts can be a real struggle. So it isnt surprising that so many people consider LASIK as an attractive alternative to treat their vision correction issues. Although it is incredibly popular, LASIK is surprisingly misunderstood. Like many things that make their way into cultural norms, LASIKs prevalence and success have led to the rise of many myths about the procedure. If you are among the millions considering LASIK, the American Refractive Surgery Council is here to dispel some common myths about the laser vision correction surgery:. ...

If you have considered vision correction surgery, you may have wondered how old you have to be to have LASIK. LASIK has been FDA approved for patients 18 or older. There is no ideal age to have the procedure, but it is important to have a stable prescription and, of course, healthy eyes.. One benefit of having LASIK done when you are younger is that there are more years to enjoy the benefit of improved vision, the eyes tend to heal quicker and stabilize faster and there are fewer side effects such as dry eyes. There are also fewer problems with reading vision than in older patients.. At first LASIK seemed to be most popular with an older demographic of an average age around late 30s or early 40s but now we are seeing many more patients in their 20s who have discovered the benefits of laser vision correction.. For patients in their 30s or 40s, LASIK is a wonderful procedure, but special consideration must be given to the management of presbyopia (need for reading glasses after age 40).. For ...
In Step two of LASIK, your doctor lifts open the flap so that the WaveLight EX500 Excimer Laser can be used on the inner cornea to correct your vision. The flap is then returned to its original position where it seals without the need for stitches.. There are some situations in which FS200 is clearly beneficial to patients looking into LASIK. The FS200 can also allow some of those who were not previously considered candidates due to thinner corneas, the ability to have the procedure. This is because the femtosecond laser is more accurate, and flaps can be made thinner. Finally, although LASIK has been performed safely for years, many potential candidates have been resistant due to fear of the mechanical creation of this corneal flap. If fear has been a major obstacle to your pursuit of laser vision correction, FS200 should provide you the peace of mind needed to move forward with the procedure.. ...

When you think about improving your eyesight, natural therapies are not usually the first thing that occurs to you. Most people make an appointment with their eye doctor, and resign themselves to the fact that they will be buying new glasses, contact lenses, or maybe even the dreaded bifocals. Your eyes, like any other part of your body, can be strengthened and protected by exercise. Your ophthalmologist probably doesnt advocate this, but since about 1910, a small group of physicians and eye care professionals have been researching and advocating natural vision correction through a system of eye exercises. Dr. William H Bates was one of the leading crusaders for eyesight improvement by natural methods. He was one of the original physicians who believed there was more to vision than the actual physical act of seeing. He believed that vision was a mind/body process that interpreted visual information. Unfortunately, for Dr. Bates, he was about seventy years ahead of his time. In his era of ...
