Estimation of corneal endothelial pump function in long-term contact lens wearers. (1/407)

PURPOSE: To study the effects of long-term contact lens wear on morphologic and physiologic properties of corneal endothelial cells. METHODS: The endothelial permeability to fluorescein and the rate of corneal deswelling from hypoxia-induced edema were measured in 20 long-term (mean, 17+/-9 years; range, 5-33 years) contact lens wearers and 20 age-matched control subjects. From these data, the relative endothelial pump rate in each subject was estimated, based on the pump-leak hypothesis of corneal hydration control. Corneal autofluorescence and the aqueous humor flow rate were determined by fluorescein fluorophotometry. Images of corneal endothelial cells were recorded by using specular microscopy, and morphologic indices (cell density, coefficient of variation of cell area, percentage of hexagonal cells, and skewness) were determined. RESULTS: No statistically significant differences were found between the contact lens and control groups in endothelial permeability, corneal deswelling, relative endothelial pump rate ([mean +/- SD] 1.07+/-0.33 relative pump units versus 1.01+/-0.25 relative pump units; contact lens versus control; P = 0.57), and endothelial cell density. Contact lens wearers had a significantly higher aqueous humor flow rate (3.57+/-1.03 microl/min versus 2.77+/-0.51 microl/min; P = 0.005), coefficient of variation of cell area (0.35+/-0.09 versus 0.28+/-0.04; P = 0.006), and corneal autofluorescence (3.1+/-0.6 ng/ml versus 2.3+/-0.3 ng/ml fluorescein equivalents; P < 0.001) than did non-contact lens wearers. CONCLUSIONS: Despite the known effects of long-term contact lens wear on corneal endothelial morphometry, no effect on endothelial function was found.  (+info)

Contact lens-induced infection--a new model of Candida albicans keratitis. (2/407)

PURPOSE: A model of experimental keratomycosis was established that mimics human disease in which the only fungi present are those that are actively growing within the cornea. METHODS: Dutch-belted rabbits received a subconjunctival injection of triamcinolone acetonide to one eye. One day later the epithelium was removed from the central cornea and a standardized inoculum of Candida albicans blastoconidia was placed on the corneal surface and covered with a contact lens. The lids were closed with a lateral tarsorrhaphy. After 24 hours, the lid sutures and contact lens were removed. Five days later the animals were killed, and their corneas were subjected to separate isolate recovery and histology studies. A group of similarly infected rabbits without corticosteroid injection served as controls. RESULTS: Both groups developed invasive corneal disease. Although isolate recovery was not significantly different from corticosteroid-treated rabbits compared with controls, fungal biomass was increased. Hyphal invasion was limited to the anterior cornea in control eyes, but penetrated deep stroma in most of the corticosteroid-treated rabbits. CONCLUSIONS: Invasive corneal disease can be established with a surface inoculum. Corticosteroid administration increased corneal penetration of hyphae. Quantitative isolate recovery is not a reliable measure of the fungal load within the cornea.  (+info)

Clinical estimation of corneal endothelial pump function. (3/407)

PURPOSE: To develop a technique to estimate the corneal endothelial pump rate in human subjects. METHODS: Corneal hydration control is thought to be maintained by a pump-leak mechanism whereby the leak of solutes and fluid across the endothelial barrier into the stroma is, in the steady state, exactly balanced by the pumping of solutes and passive fluid transfer across the endothelium to the aqueous humor. Overall corneal hydration control can be measured from the rate at which the swollen cornea thins (deswells), and a measure of the leak can be obtained simultaneously from the endothelial permeability to fluorescein. From the pump-leak hypothesis, the deswelling rate is directly proportional to the pump rate and inversely proportional to the leak rate. The relative endothelial pump rate can be estimated as the product of the normalized deswelling rate and the normalized endothelial permeability. This procedure was used to obtain the relative endothelial pump rate in 41 patients with diabetes mellitus, 12 patients with long-term corneal transplants, 20 long-term wearers of contact lenses, and 19 normal volunteer subjects after the short-term administration of topical dorzolamide. RESULTS: The relative endothelial pump rate did not differ significantly from that of control subjects in diabetics, in contact lens wearers, and after dorzolamide administration, but was markedly decreased in the patients with corneal transplants, despite a reduction in permeability (reduced leak). CONCLUSIONS: This method allows the estimation of both the barrier and pump arms of corneal endothelial function and should be useful in the investigation of causes and mechanisms of functional endothelial insufficiency.  (+info)

Rehabilitation of children with cataracts. (4/407)

Over a period of 10 years, 160 children with cataracts underwent operation at the University of Tennessee Medical Center, Memphis. The surgical, optical, and psychosocial rehabilitation of these patients was analyzed and studied. The optical rehabilitation included patients with glasses, intraocular lens implants, epikeratophakia, and contact lenses. Seventy three of these patients were chosen at random and reevaluated as to visual outcome, and 46 were subjected to a psychosocial test to evaluate their quality of life and their rehabilitation. Eighteen of these were also given a psychosocial test to evaluate the quality of life enjoyed by these children at an older age following treatment for the cataract. Surgical, optical, and psychosocial rehabilitation of such children is also discussed. This is the first report of the psychological evaluation of such children. The further needs of these children as they approach adulthood are discussed in detail.  (+info)

Rapid improvement in the acuity of infants after visual input. (5/407)

Visual acuity was assessed in 28 human infants who had been deprived of all patterned visual input by cataracts in one or both eyes until they were treated at 1 week to 9 months of age. Immediately after treatment, acuity was no better than that of normal newborns. Acuity improved significantly over the next month, with some improvement apparent after as little as 1 hour of visual input. Unlike findings at older ages, the pattern of results was the same for eyes treated for monocular and for binocular deprivation. The results indicate that patterned visual input is necessary for the postnatal improvement of human visual acuity and that the onset of such input initiates rapid functional development.  (+info)

Measurement of post-lens tear thickness. (6/407)

PURPOSE: A method to measure the tear film beneath a soft contact lens, referred to as post-lens tear thickness (PLTT), would have many applications to contact lens research. In this study a noninvasive technique for measuring the PLTT is presented. METHODS: The feasibility of measuring the tear layer by optical pachometry was first assessed using a model eye. The baseline corneal thickness (B) of both eyes of 21 subjects was measured, etafilcon-A ionic disposable soft contact lenses (58% water) were inserted, and the total thickness (T) of the cornea, contact lens, and PLTT were measured. After the pachometry readings the lenses were removed and their center thickness (C) determined. The PLTT was calculated using the equation: PLTT = T-(B+C). Two sets of measurements of T were performed at 15 and 25 minutes after lens insertion. The entire procedure was repeated at a second visit. RESULTS: The pachometry measurements of the small aqueous reservoir between the model eye and the lens closely matched those obtained by direct microscopic measurement. For human PLTT, the mean values (and 95% confidence intervals) for right eyes on visits 1 and 2 were 11 (8, 13) and 12 (10, 15) microm, respectively, and for left eyes were 12 (10, 15) and 11 microm (8, 14) microm, respectively. CONCLUSIONS: It is possible to measure the post-lens tear thickness using optical pachometry. The variability between repeated measurements suggests that with careful sample size planning, the technique is sufficiently precise to be useful in group assessments of PLTT.  (+info)

Isoenzyme patterns and phylogenetic relationships in Acanthamoeba spp. isolated from contact lens containers in Korea. (7/407)

In order to refer to the basic information regarding the identification of isolates obtained from a contact lens container in Korea, the isoelectric focusing gel electrophoresis was employed to compare the isoenzyme band patterns among Acanthamoeba spp. including eight isolates and the simple pairwise dissimilarity analysis was carried out. For an alkaline phosphate development, isolate 7 and Acanthamoeba polyphaga showed homologous band patterns, and isolates 1, 2, and 3 showed the same patterns. For lactate dehydrogenase, similar patterns were observed in isolates 2 and 3. Isolates 3 and 5 showed homologous band patterns for malate dehydrogenase and glucose phosphate isomerase. For hexokinase, isolates 4, 7, and A, hatchetti showed the same band patterns. In others, a considerable number of interstrain polymorphisms was observed in nine isoenzyme band patterns. In Acanthamoeba group II, genetic distances among isolates 1, 2, 3, 4, and 5 ranged from 0.104 to 0.200. In comparison to A. castellanii, A. hatchetti, and A. polyphaga, genetic distances of isolates 7 and 8 were 0.254 and 0.219, respectively. In Acanthamoeba group III, including A. culbertsoni, A. healyi, and A. royreba, isolate 6 had genetic distances which ranged from 0.314 to 0.336. Finally, when comparing to the six reference Acanthamoeba, it was possible to classify isolates 1, 2, 3, 4, and 5, as genetically close-related species and as independent species group. Furthermore, isolates 6, 7 and 8 were identified as independent species as well.  (+info)

Clinical course of hurricane keratopathy. (8/407)

BACKGROUND/AIMS: "Hurricane keratopathy" is the name given to the whorl pattern, highlighted with fluorescein, seen in situations where corneal epithelial cell turnover is exaggerated. Although the condition is well described, follow up data on patients with this condition and its sequelae have only been reported in corneal graft patients. The aim was to study the clinical course of hurricane keratopathy in corneal graft patients and contact lens wearers, and to document any sequelae of this condition. METHODS: Hurricane keratopathy, occurring in 20 eyes with corneal grafts and 16 eyes (six bilateral) wearing rigid gas permeable contact lenses, was studied and followed. The occurrence, pattern, progress, resolution, and residual effects of the whorls were noted. RESULTS: Hurricane keratopathy was noted to occur in grafts as previously reported and also in contact lens wearers, which has hitherto not been reported. The whorls usually appeared within the first 3 weeks postoperatively and persisted up to 4 months. A small epithelial defect (11.1%), heaped epithelial cells (5.6%), and a nebular grade opacity (2.8%), were the only significant sequelae noted at the epicentre of the whorls. Resolution occurred from the periphery towards the centre of the cornea. CONCLUSIONS: The whorl pattern is sustained as long as the stimulus for increased cell turnover is maintained. Once this stimulus is eliminated, the pattern tends to resolve spontaneously.  (+info)

Gas permeable contact lenses may not be as well known as the soft type, but for many conditions these lenses can be ideal when soft lenses will not work or are not preferred. They may also be called rigid gas permeable contact lenses or even at times oxygen permeable lenses. A common misunderstanding is that many people think these lenses are the hard ones first available a long time ago, and that is not the case. Original lenses did not allow oxygen through the barrier, but this new type first developed in the 1970s does.. There are some benefits that gas permeable contact lenses offer over the soft variety. Better results can usually be seen for many conditions, and this is true with toric contact lenses as well. GP lenses are very durable and meant to last longer, so while they may cost more initially they are actually cheaper over time. The rigid lenses have a higher resistance to deposits on the lens, so there is nothing to cause discomfort while wearing them. Cleaning is very simple, and ...

Purpose : Corneal epithelial dryness or damage is more concerned in complicated proliferative diabetic retinopathy (PDR) surgery if using noncontact wide-angle viewing system. We designed a rigid contact lens to be used during surgery and performed a prospective, randomized, comparative study to analyze its protection of corneal epithelia.. Methods : A thin and lightweight rigid contact lens was designed and constructed. The impact of the contact lens on the visualized fundus range was evaluated using a concrete eye model. Eighty two eyes of 74 patients with severe PDR were randomized to either the contact lens (CL) group, viscoelastic group (VIS), or balanced salt solution (BSS) group. Surgery time and corneal fluorescein staining score (FSS) postoperatively were mainly measured using one way analysis of variance (ANOVA) test.. Results : In the eye model, a larger area of fundus was visualized with the use of our contact lens under the 128D (,80°) and 60D (45°) Resight lens compared to the ...

With the evolution of different types of contact lenses, a large number of options are now available for the existing as well as new contact lens users. The soft contact lens provides several advantages over the conventional rigid gas permeable contact lens. These lenses are easy to adjust and are made up of soft and flexible plastics that allow oxygen to pass through the cornea. Soft contact lenses also render high comfort as compared to rigid gas permeable contact lenses. Owing to these factors, soft contact lenses are estimated to record highest growth rate during the forecast period. On the other hand rigid gas permeable lenses are durable, resistant to deposit buildup and are easy to handle. However, the demand for the same is declining due to increasing preference for various kinds of soft contact lenses such as daily disposable, extended wear and weekly replacement contact lenses. Daily disposable and extended wear soft contact lenses markets represent two of the largest markets of 2012. ...

Halloween contact lenses. Halloween contact lenses are also known as decorative contact lenses, costume contact lenses, novelty contact lenses, or special effect contact lenses. People use these contact lenses to elevate the look of their costumes on Halloween. Actors and actresses also use these contact lenses when playing characters such as vampires, werewolves, or zombies in movies and TV shows.. Most Halloween contact lenses are purely cosmetic (Plano), which means they wont correct your vision. The FDA considers these types of contact lenses as medical devices just the same, so youll still need a valid prescription from your eye care professional if you plan on buying a pair.. Buying Halloween contact lenses. You can buy Halloween contact lenses from ecommerce contact lens sites, brick-and-mortar stores, and even at the offices of some eye care professionals. However, shopping for Halloween contact lenses online is your best option. Here are three reasons why:. ...
For Use: Before First Use: Rinse lens case and caps thoroughly with fresh contact lens disinfecting solution. Chemical Disinfection: Clean and rinse contact lenses as directed by eye care professional. Place contact lenses into their correct chamber of the contact lens case, fill with fresh contact lens disinfecting solution, and tightly close the caps. Leave the contact lenses in the lens case according to the directions provided with your contact lens disinfecting solution. Important: If a contact lens chamber appears to be dry following the disinfection cycle, do not try to remove the contact lens. Refill the chamber with fresh saline or contact lens disinfecting solution, replace lens cap tightly and allow 20-40 minutes for the contact lens to rehydrate. If a lens chamber continue to dry out, the case should no longer be used and should be replaced. For Good Contact Lens Care: After each use, rinse both lens case and caps with the fresh contact lens disinfecting solution used in your contact ...
Purpose: To calibrate the axial and lateral dimensions of spectral domain optical coherence tomography (SDOCT) images using rigid gas permeable (RGP) contact lenses. To quantify the physical and optical characteristics of RGP lenses using cross sectional OCT imaging.. Methods: The parameters of 5 spherical RGP lenses of the same design, index of refraction = 1.433, were manually verified. The posterior side of each lens was mounted on a flat surface and imaged using the Heidelberg Spectralis SDOCT system with Anterior Segment Module (Heidelberg Engineering, Carlsbad, CA). The 30 deg image included the entire cross section of the central lens and extended beyond the lens boundaries to included locations of the mounting platform only, which was used as an axial reference. The lateral and axial pixel dimensions were calculated and divided by the known diameter of the contact lens and center thickness. The index of refraction of the lens material was used to compensate for the thickness changes ...
Purpose: Discontinuation from contact lens wear has been identified as a contributing factor in the lack of growth of contact lens use in Europe. The purpose of this study was to determine the proportion of lapsed contact lens wearers that can be refitted successfully with contact lenses and to evaluate the reasons for discontinuation from contact lens wear. Methods: This was a multi-site clinical study involving 15 UK investigators and 236 lapsed contact lens wearers who had previously tried contact lenses and discontinued. The reasons for discontinuation were assessed by subjects, who were then refitted with contact lenses. Investigators subsequently evaluated factors associated with their initial discontinuation. Short-term success was defined as the successful completion of 1 month of contact lens wear with absence of complications that would prevent further wear. Subjects were interviewed by telephone 6 months after being refitted to determine whether they were still wearing contact lenses. ...

Purpose: Nerve growth factor (NGF) has been shown to be upregulated in conditions, which damage corneal nerves and to relieve dry eye. How NGF changes in nerve injury induced by established contact lens wear is not clear. The purpose of this study was to measure the subepithelial nerve plexus and tear NGF and transforming growth factor (TGF)-β1 levels in patients with established contact lens associated with dry eye.. Methods: Non-contact lens wearers and subjects who had worn soft contact lenses for more than 1 year were recruited and were divided into three groups: (1) normal controls; (2) contact lens wearers without dry eye; (3) contact lens wearers with dry eye. Corneal sensitivity was measured with a Cochet-Bonnet aesthesiometer. Nerve density and branching in the subepithelial plexus were measured using in vivo confocal microscopy. Tear NGF and TGF-β1 levels were measured with an enzyme immuno assay.. Results: There was a statistically significant decrease of corneal sensitivity in ...
Contact lens wearers are susceptible to a variety of conditions that are either directly or indirectly linked to contact lens use. These conditions can be loosely grouped into three categories: hypoxia, an oxygen deficiency condition; allergic reactions and infections; and dry eye. Both soft and hard contact lens wearers can be affected by any of these conditions. Our doctors have significant experience with diseases affecting contact lens wearers.

Brand new article on our personal ...
For many years, the contact lens field had focused on safety associated with contact lens wear-and for good reason, given the lack of understanding of the risk factors and etiology of serious complications such as microbial keratitis. However, as knowledge came to light on these complications through the 1980s and 1990s, it allowed for practitioners to become more comfortable managing these complications, along with the introduction of products that helped reduce or prevent some of these problems. It was during this time, beginning in the mid-1980s, that the field itself became cognizant of the issues associated with comfort, or discomfort, during contact lens wear. Since that time, we have witnessed the field (and industry) shift its attention toward understanding the issue of contact lens discomfort (CLD). Contact lens discomfort is a substantial and burdensome problem experienced frequently by contact lens wearers. It is well established that most contact lens wearers experience CLD, at least ...

Microbial corneal infection is the most serious and most common vision threatening complication of contact lens wear, which is believed to be strongly associated with contact lens cases. Such infections are being increasingly recognized as an important cause of morbidity and blindness and may even be life-threatening. While the cornea is believed to be the most common site for fungal eye infections, other parts of the eye such as the orbit, sclera, eyelids, and more may also be involved. Contact lens cases are recognized as a potential source of pathogens associated with corneal ulcers and according to Moorfields Eye Hospital, contact lens wear is the most prevalent risk factor for new cases of corneal ulcers. Contaminants isolated from contact lens associated corneal ulcers have often been shown to be the same as found in the patients contact lens case, thus providing evidence contaminated contact lens cases may be a replenishable source of pathogenic microbes. In the study ...

Rigid Gas Permeable (RGP)-or just Gas Permeable (GP)-lenses are sometimes mistaken for old-fashioned lenses. The old hard contact lenses that people know are rarely used today. RGP lenses are more pliable, more comfortable, and they allow oxygen to the cornea. Gas permeable lenses allow more oxygen to the cornea than traditional soft contact lenses. They do not change their shape when you blink or move your eyes because they are rigid. This means they offer sharper vision than soft contacts. They are much more durable than soft lenses. Because they do not contain water, proteins and lipids do not adhere to them like they can do with soft lenses. RGP lenses also come in many bifocal and multifocal designs.. The biggest disadvantage of RGP lenses is that patients need to get used to them. They are not immediately comfortable like soft lenses. RGP lenses take 3 to 4 days for patients to adapt to them. They need to be worn regularly (although not every day) to achieve optimal comfort. They are ...

WE often think about wearing sunglasses to protect our eyes from the suns glare, but as a contact lens wearer do you know if your contact lenses filter harmful UV light?. A study conducted by the American Academy of Optometry on 400 contact lens wearers in the UK found that a huge 74 per cent didnt know that many contact lenses have UV blocking technology.. The sun radiates UVA and UVB rays which are damaging to both the bodys eyes and skin and over exposure to either can cause eye conditions and diseases such as photokeratitis (sunburn of the cornea) and in more extreme cases as a result of long term damage, cataracts. Ultraviolet light can also enhance the effects of Age-Related Macular Degeneration, a condition that usually occurs in those aged over 50 where the central vision begins to deteriorate due to the destruction of the macular.. Its very important to protect your eyes from the sun to prevent conditions that can lead to sight loss and even blindness in the future. By wearing CE ...
With Halloween on the way its important to stress that you should ONLY purchase contact lenses from an eye doctor or legally authorized contact lens seller with a prescription. Even if you are purchasing purely decorative contact lenses with no vision correction, you need a doctor to measure your eye to ensure they fit properly. Contact lenses are a medical device and it is illegal to sell them without proper authorization. Therefore you should never purchase them from a costume or party store - they are unregulated and could cause serious harm to your eyes and vision.. If you notice any unusual redness, discharge, crusting, light sensitivity or pain, immediately remove your contact lenses and go see your eye doctor as soon as possible. Some serious eye infections can cause permanent vision damage or loss even within a day or two..

Dow Jones ran an article last week speculating on the possible impact the recent contact lens solution infections will have on daily contact lens sales. This comes after the U.S. Centers for Disease Control issued a warning last month of a possible connection between the Acanthamoeba keratitis eye infections and a lens solution made by Advanced Medical Optics Inc. This is the third case of a suspected infection among top brand contact lens solutions over the past year.. According to the article the common perception among analysts, doctors and contact lens manufacturers is that the ongoing concern of infections with the use of monthly or yearly lenses (requiring cleaning with solutions) could boost the sales of daily contact lenses. Using daily contact lenses eliminates this concern since a new pair is used each day and no cleaning solution is required.. So far sales of daily contact lenses in the United States only account for a small percent of contact lens sales due to their higher price ...

This study confirms the positive therapeutic effect of contact lenses in some patients with congenital nystagmus for whom few treatments are available. Much of the clinical improvement observed in our patients may result from a better optical correction of their refractive error with contact lenses than with spectacles, rather than a true damping effect of the nystagmus by contact lens wear. It is also possible that contact lenses had a placebo effect on our patients who strongly believed contact lenses helped them with daily activities. Visual acuity was slightly improved in all patients, and their contrast sensitivity was better with contact lens wear.. All patients had an important refractive error that was most likely better corrected with contact lenses than with spectacles. Indeed refractive disorders are more common in patients with congenital nystagmus than in the general population, and accurate refraction is the best way to improve visual acuity in patients with nystagmus.9 However, ...
An in vitro model-blink cell that mimics break-up of the tear lipid layer Peng et al. developed an in vitro model-blink cell that closely represents how the tear lipid layer breaks up over the contact lens during a blink.3 Their model-blink cell works by first placing a soft contact lens in a Teflon mold that leaves the anterior surface of the contact lens exposed to the treatment conditions.3 The investigators then add an aqueous layer with a mixture of proteins to the chamber, which is followed by a layer of artificial-tear lipid solution.3 The blink is then simulated by removing the aqueous layer until there is a break in the aqueous layer, which results in the lipid layer making contact with the contact lens.3 The aqueous solution is then replaced, and the process repeated to simulate normal contact lens wear.3. Validation of their apparatus demonstrated that the device was able to produce lipid deposition patterns similar to that of human worn contact lenses.3 Peng et al.s apparatus and ...
SATURDAY, Aug. 19, 2017 (HealthDay News) -- Keep your eye on your contact lens regimen if youre traveling this summer.. Being prepared when traveling is key to eye safety, said Dr. Andrew Pucker, an associate professor at the University of Alabama at Birmingham School of Optometry. While the vast majority of contact lens wearers believe they are compliant, up to 90 percent of patients fail to accurately complete at least one step of their care regimen, Pucker noted.. Either they wear contact lenses for more days than recommended, keep them in overnight, expose their lens to tap water or fail to fully follow the cleaning instructions given to them by their optometrist, he said.. Taking shortcuts in your eye care while traveling can exacerbate bad habits or create new dangers.. Here, Pucker provides tips about contact lens safety for vacationers:. Consider your destination: Not all travel destinations have the same resources as the United States, Pucker said. You could lose your lenses and ...
It has been very frustrating for me, a contact lens practioner, because contact lens care products that I have recommended to patients for years, products that worked and which patients had no problems with, have either been discontinued or are difficult to get. Many of these products were developed before disposable contact lenses became readily available and because of the cost of individual contact lenses contact lens cleaning and disinfecting seemed more important the manufactures in those days. The fact is that many people now over-wear their disposable contact lenses and unless they wear 1 day disposable contact lenses and use them as directed cleaning and disinfecting is still important. ...

The early stages of pellucid marginal degeneration may also be managed with soft contact lenses.[2] Success has been shown with the use of rigid gas permeable contact lenses combined with over-refraction. People wearing contacts dont report increased problems with glare and contrast sensitivity, but it is not clear if this is due to the corneal disease, or the contact lenses themselves. New studies found that the use of Scleral contact lens, a type of rigid gas permeable (RGP) lens, may be a good option for most people with PMD. Most of these lenses are in the range of 15.5mm to 18.0mm in diameter. Regardless of the lens size, it is thought that the larger the RGP lens will in most cases be more comfortable then standard rigid corneal lenses, and at times more comfortable than soft lenses, regardless of the fact that it is a rigid lens. The highlight to the scleral design and the correction of eye disorders such as pellucid marginal degeneration is that vision with these types of lenses is ...

We will discuss your visual function and decide if contact lenses might serve your unique needs the best. A properly fitting lens will give you the best comfort while maximizing clarity. The Keratometer will be used to measure corneal curvature to ensure a properly fit lens. The tear layer of the eye will be assessed to find the best contact lens material match with your personal tear film quality and quantity, which will ensure maximum comfort potential during your wearing schedule. We may also order a corneal topography scan, which ...
One could argue everyday living conditions are nonideal for the majority of contact lens wearers on this planet. The smoke at the corner bar, reading never-ending e-mails, or even traveling to work in an air-conditioned or heated car can compromise contact lens wear. Think about it: contact lenses are asked to peacefully coexist within the protein and lipid-rich tear film of a patient that lives in a world filled with ubiquitous organisms just waiting to become opportunistic pathogens. Additionally, contact lenses not only increase the evaporation rate of the tear film but can create their own suboptimal environment by adding hypoxic stress with daily and especially overnight use, or through the solutions in which they are bathed.. Fortunately, contact lens associated infection remains rare, and comfort is continually improving. Certainly, industry has given us tools to efficaciously treat just about any refractive error while attempting to combat hypoxia and discomfort. Obviously, they are ...
For people with Keratoconus contact lenses are often the best way to achieve vision correction. There are many different types of lenses and this article looks at the limitations of Hydrogel lenses for Keratoconus.. Keratoconus is a disease of the eye. The cornea, which is the front part of the eye, thins and becomes misshapen leading to the front of the eye developing an irregular cone shape.. This bulging effect results in distortion of the light entering the eye causing blurring and ghosting of images.. While spectacles may produce some correction for early, or very mild, cases of Keratoconus, once the condition progresses beyond a certain point it becomes impossible to get reasonable correction with spectacles.. Contact lenses are often the next form of correction used, however there are many different types of contact lenses and some of them are more effective than others.. Hydrogel lenses are what are sometimes called soft contact lenses.. Traditional Hydrogel lenses are very soft and ...

The unexpected keratitis outbreaks prompted FDA to explore the various risk factors involved with using multipurpose contact lens solutions. In both outbreaks, FDAs investigation revealed that reusing previously used solution and adding to it fresh, unused solution reduced the antimicrobial effectiveness of the lens care product. Therefore, FDA recommended that contact lens care solution should be emptied out of the contact lens case after each use. The solution left over in the contact lens case after a disinfection cycle is dirty, said Bernard Lepri, OD, MS, MEd, of the Division of Ophthalmic and Ear, Nose, and Throat Devices in the FDAs Center for Devices and Radiological Health. Lepri stated, The left-over solution can have little disinfecting chemical left to kill bacteria and other micro-organisms that may contaminate your contact lenses and lead to serious eye infections. The solution no longer has the same effectiveness for disinfection as when it was freshly placed in the case. On ...
The problem persisted and Ive actually started wearing my glasses more because my contact lenses just werent as comfortable to wear for long periods of time. Then, I decided to take the Biotrue Challenge - a 1 month challenge where I switched from my usual contact lens solution to Biotrue multi-purpose contact lens solution.. Biotrue is a new multi-purpose contact solution that has the same pH and lubricant that our eyes naturally have. Not only does it condition, clean, remove protein, and disinfect lenses when you follow proper usage instructions, but it helps your contact lenses feel more comfortable throughout the day.. Im only partially through my first month of using Biotrue but Ive already noticed a big difference. With my old solution, I would noticeably feel my eyes getting dry late at night. One glance in the mirror and I could see where my eyes were starting to turn red. Since switching to Biotrue multi-purpose solution, Ive been able to stay up longer without any contact ...

Benzyldimethyl {2-[2-(p-1,1,3,3-tetramethylbutylphenoxy)ethoxy]ethyl} ammonium chloride (BDT) forms the basis of contact lens solutions that are unusually effective at reducing the number and wide variety of pathogenic microorganisms that may infect rigid gas permeable or soft contact lenses. Furthermore, it has been discovered that natural occurring compounds alone and in combination with chemical agents can be used in ophthalmic solutions such as contact lens solution to enhance and complement their anti-microbial, cleaning and wetting activity or to reduce irritation to the eye. The basic contact lens solution comprises an effective concentration of BDT (preferably 1 to 100 parts per million), with naturally occurring plant products possessing activities complementary to BDT, in an isotonic diluent buffered with a physiologically acceptable buffer to a physiologically natural range.

Global RGP Contact Lenses Market Research Report 2017 is a market research report available at US $2900 for a Single User PDF License from RnR Market Research Reports Library.
The oral microbial ecology is comprised of hundreds of bacterial species that co-exist as multispecies biofilms throughout a range of ecological niches in the oral cavity. However, little is known concerning the interactions of these complex biofilms with host cells. Objective: This study used a novel model of multispecies bacterial biofilms to stimulate oral epithelial cells and profile select cytokines and chemokines that contribute to the local inflammatory environment in the periodontium. Method: Three multispecies biofilms comprising Streptococcus gordonii/S. oralis/S. sanguinis, Sg/Fusobacterium nucleatum/Porphyromonas gingivalis and Sg/Actinomyces naeslundii/Fn were grown for 3 days on rigid gas permeable contact lens pre-coated with 1% fetal bovine serum. OKF4 oral epithelial cells were cultured in 48 well plates at 105 cells/well, which were challenged with the biofilms for 24 hrs. Controls included incubation of the epithelial cells alone or overlaid with contact lens alone. A profile ...
In a 2010 study, Wu et al attempted to determine the most effective care regimen for removing bacterial biofilms from contact lens cases.5 In their study, they inoculated contact lens cases with common biofilm-forming bacteria, and they analyzed how care regimen steps affected contact lens case biofilm formation (no treatment, case rinsed with multipurpose solution, rubbing and rinsing the case with multipurpose solution, air drying the case face down, recapping the case, drying the case with tissue, and soaking the case in multipurpose solution).5 Wu et al found that the most effective means for reducing bacterial biofilms was rubbing and rinsing the cases with multipurpose solution and drying the cases with tissue, which indicated to the authors that application of mechanical force to the contact lens case may be the most important factor for removing stuck-on biofilms.5 Your patients may be surprised by the need for good case hygiene, so this is an especially important topic to add to your ...
Rigid and soft contact lenses have also attempted to address the challenges of correcting presbyopia, but with limited success. Rigid multifocal or bifocal lens wearers often experience a momentary blur after blinking and also have to settle for less-than-optimal comfort. Soft multifocal contact lenses can be comfortable and convenient, but visual acuity is often fuzzy and blurred at best. In addition, most soft multifocal contact lenses do not correct corneal astigmatism.. An alternative approach to treat presbyopia with soft lenses is monovision, which requires the patient to wear a distance vision soft lens in one eye and a near vision soft lens in the other eye. Monovision is acceptable for some patients, but others are unable to adapt to each eye working alone and often report a loss of depth perception.. Currently, presbyopic patients have to compromise on visual clarity or comfort in order to wear contact lenses, but the SynergEyes Multifocal changes that, said Kellie Kaseburg, Vice ...
Rubbing reusable, non-daily disposable contact lenses is analogous to brushing your teeth. If the surface of the lens is not clean it isnt likely to get disinfected. Lens disinfection ought to involve cleaning the lenses by rubbing them with clean hands and fresh contact lens solution. Rinsing and soaking the contacts in fresh solution in a clean case are all required for proper, safe lens care. Deposits can form on contact lenses in minutes and hours, not just over days and weeks. This means that even lenses that are disposed of after a few weeks of wear still require ongoing cleaning.

Since 1978, the USAs National Institute for Occupational Safety and Health (NIOSH) has recommended that workers not wear contact lenses when working with chemicals that can irritate or harm the eyes. In recent years, however, several groups have issued new guidelines that remove most of the previous restrictions on the wearing of contact lenses where there is risk of chemical exposure.. Given the new guidelines, and because there is a lack of data indicating that contact lens wear is harmful in the presence of hazardous chemicals, NIOSH has issued a Current Intelligence Bulletin (CIB) to disseminate new scientific information and make new recommendations.. NIOSH recommends that workers be permitted to wear contact lenses when handling hazardous chemicals, provided that these safety guidelines are followed: ...

Therapeutic uses of scleral contact lenses for ocular surface disease: patient selection and special considerations Jennifer S Harthan,1 Ellen Shorter2 1Illinois College of Optometry, Chicago, IL, USA; 2University of Illinois at Chicago, Chicago, IL, USA Abstract: Scleral lenses are being prescribed for the management of corneal irregularity, uncomplicated refractive error, and ocular surface disease. There are many potential therapeutic uses of scleral lenses in addition to providing similar benefits as corneal gas permeable lenses. Scleral contact lenses are a valuable therapeutic tool for patients with ocular surface disease as these lenses protect the ocular surface, provide continuous corneal hydration while providing optimal visual correction, and are often used in conjunction with other therapies. Keywords: scleral lenses, ocular surface disease, contact lenses

Studies show that a slight difference in the formulations of contact lens solutions makes a huge difference in each patient. MPS or also known as Contemporary multipurpose solutions have dramatically improved over the past couple of years. The improvement of such product made the life of each contacts user around the globe so much better.. The original formulation of the solution contained chlorhexidine and thimerasol, both of these ingredients are extremely tough in cleaning, specifically in disinfecting and sensitizing the contact lenses. This strong solution often result into many cases of eye irritation for the patient like red eyes which can be very uncomfortable and can damage their eyes in the long run.. The new breed of solution however, contains various types of ingredients like Polyquad (or in medical term, polyquaternium-1) ), Aldox (myristamidopropyl dimethylamine and PHMB (polyhexamethylene biguanide). These ingredients are kinder to the eyes, and does not usually cause any forms of ...
