keratoconus treatment 2019

You are encouraged to report all side effects to the FDA. This imbalance makes the cornea more susceptible to oxidative damage from compounds called free radicals, causing it to weaken and bulge forward. As a treatment for low myopia, Intacs ® corneal implants were a market failure since LASIK provided better, more consistent results with a lower complication rate. Vinciguerra R, Ambrósio R, Roberts C, Azzolini C, Vinciguerra P. Biomechanical characterization of subclinical keratoconus without topographic or tomographic abnormalities. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision. This drug, with its copper-based formulation, is reportedly the first eye drop designed to treat keratoconus without the need for adjunctive laser treatment or surgical intervention. Researchers have found that epithelial thickness is fairly uniform from the center to the periphery in healthy corneas. The original Dresden CXL protocol is time-intensive, requiring 30 minutes for riboflavin instillation followed by continuous application of UV-A radiance at 3 mW/cm² for 30 minutes, for a total treatment time of 1 hour.6 Theoretically, the UV-A intensity can be increased and illumination time proportionally decreased, resulting in the same photochemical effect. 72. Keratoconus is a progressive eye condition that affects the cornea, causing it to bulge out. 18 While the “Dresden protocol” with epithelial removal is an established standard, some corneal surgeons are now performing variations of CXL, including trans-epithelial (epi-on) application of riboflavin drops. We do not endorse non-Cleveland Clinic products or services. 5. To learn more and to find an eye doctor who prescribes and fit these prosthetic lenses, visit the EyePrint Prosthetics website. The Avedro KXL system is indicated for treatment of progressive keratoconus in patients ages 14 and older by first debriding the corneal epithelium. Supported by the National Keratoconus Foundation, this safe, minimally invasive outpatient procedure works by stiffening the weakened cornea to slow or halt progression of the disease. Keratoconus: A Roadmap to Treatment [October 8, 2019 Webinar] Please enjoy this recording of our webinar: “Keratoconus: A Roadmap to Treatment” This webinar was led by our moderator, Dr. Jason Marsack, who discussed with Dr. Maria Walker and Dr. Matt Kauffman from the University of Houston, College of Optometry, where they shared their insight to what the newly diagnosed KC patient can … In 2003, WaveLight developed technology to perform topography-guided excimer laser treatment. Hallahan KM, Sinha Roy A, Ambrósio R Jr, Salomao M, Dupps WJ Jr. Discriminant value of custom ocular response analyzer waveform derivatives in keratoconus. It is a photoenhancer indicated … To learn more, talk to your healthcare provider. Since then, the procedure has been completed more than 18,000 times at more than 300 practices nationwide. Get useful, helpful and relevant health + wellness information. Available Treatment Options. Figure 2. Keratoconus Treatment Options. 13. Keratoconus Treatment. A. John Kanellopoulos, MD, developed the Athens protocol and has investigated the safety and efficacy of both sequential and simultaneous treatments. (Glaukos recently acquired Avedro.). Accelerated corneal collagen cross-linking in thin keratoconic corneas. Because the center of scleral and semi-scleral lenses vaults over the irregularly shaped cornea, these lenses don't apply pressure to the eye's cone-shaped surface for a more comfortable fit. The most common ocular side effect is haze. The best treatment for keratoconus will depend on its severity and how quickly it is progressing. New technologies are improving our ability to diagnose keratoconus earlier than ever before and facilitating visual recovery with remarkable results. Keratoconus is a non-inflammatory eye condition in which the normally round dome-shaped clear window of the eye (cornea) progressively thins causing a cone-like bulge to develop. Cleveland Clinic is a non-profit academic medical center. Brian Boxer Wachler, MD, is an ophthalmologist and refractive surgeon at the Boxer Wachler Vision Institute in Beverly Hills, Calif. [65] [66] The Save Sight Keratoconus Registry is an international database of keratoconus patients which is tracking outcomes of cross-linking in patients with keratoconus. Researchers are investigating ways to combine CXL with excimer laser ablation to not only strengthen ectatic corneas but also improve BCVA. We do not endorse non-Cleveland Clinic products or services. There are Many Treatment Options for Keratoconus. One example are lenses made with the EyePrintPRO process (EyePrint Prosthetics). Because eyeglasses and soft contact lenses often cannot provide adequate visual acuity in cases of keratoconus, gas permeable contact lenses usually are the preferred treatment. Tell your healthcare provider if you are pregnant or plan to become pregnant. This is a non-invasive treatment for patients with keratoconus. This treatment uses energy from radio waves, applied with a small probe at several points in the periphery of the cornea to reshape the eye's front surface. Recent research has shown that this approach can shorten epithelial healing times because of the smaller abrasion zone needed and also strengthen the flattening effect.11. Go to www.livingwithkeratoconus.com/ to obtain the FDA-approved product labeling. enews. With the simultaneous approach, TG-PRK is followed immediately by CXL. Tissue engineering is the science of improving or replacing biological tissue using various growth factors. Eyeglass temples: How do you know if they're the right length? While keratoconus can be a challenging condition, it can be managed effectively when detected early. Postoperative UCVA was 20/25. Accessed 8/27/2019. Molokhia S, Muddana SK, Hauritz H, et al. At A Glance. Because fitting a gas permeable contact lens over a cone-shaped cornea can sometimes be uncomfortable for a person with keratoconus, some eye care practitioners advocate "piggybacking" two different types of contact lenses on the same eye. Intacs may be needed when keratoconus patients no longer can obtain functional vision with contact lenses or eyeglasses. Ophthalmologist, North Suburban Eye Specialists, Coon Rapids, Minnesota, Financial disclosure: Owner and Developer (Phorcides Software); CEO (American Corneal Consultants); Consultant (Alcon), Coming Soon: Presbyopia-Correcting Eye Drops, Joshua Davidson, OD, FSLS, FAAO; and Paul Kimbro, OD, Myopia Control With Multifocal Contact Lenses, Roxanne Achong-Coan, OD, FAAO, FIAOMC, FSLS, © 2021 Bryn Mawr Communications, LLC. Click here to find a cornea specialist near you. What happens to FSA dollars at the end of the year? These medium-water hydrogel lenses can correct up to 30 D of nearsightedness or farsightedness and up to -10 D of astigmatism. Keratoconus usually affects both eyes and generally begins to first affect people ages 10 to 25. Because simultaneous treatments were found to produce the best results, we use the following regimen. Keratoconus also is associated with overexposure to ultraviolet rays from the sun, excessive eye rubbing, a history of poorly fitted contact lenses and chronic eye irritation. Are contact lenses a good choice for kids? The aim of corneal cross-linking is to strengthen the cornea by increasing the number of "anchors" that bond collagen fibers together. doi: 10.1111/aos.13814. OCT epithelial mapping will not replace corneal tomography, but it can provide supplemental information that should improve early detection of subclinical keratoconus. Ophthalmologists have long believed that they should never perform PRK or LASIK on an eye with ectasia because of the risk of worsening the condition. Several studies have supported this concept of accelerated protocols and have shown similar results in arresting keratoconic progression with illumination times ranging from 3 to 10 minutes.7,8 This approach is becoming more popular with corneal surgeons around the country because it is more convenient for patients and for the surgical team. These are large-diameter gas permeable contacts — large enough that the periphery and edge of the lens rest on the "white" of the eye (sclera). OCT epithelial mapping can provide supplemental information that should improve early detection of subclinical keratoconus. UltraHealth and ClearKone are available in a wide variety of parameters to provide a fit that conforms well to the irregular shape of a keratoconic eye. Keratoconus Diagnosis and Treatment - American Academy of Ophthalmology Keratoconus diagnosis include a comprehensive eye exam and tests to determine your corneal shape. Efficacy of different accelerated corneal crosslinking protocols for progressive keratoconus. Some people with keratoconus can't tolerate a rigid contact lens, or they reach the point where contact lenses or other therapies no longer provide acceptable vision. When considering cataract surgery in patients with keratoconus, there may be certain factors to take into account before developing a surgical plan.Experts discussed treatment options for these patients, steps to take before surgery, how they decide on a plan of action, and appropriate lens options. This eventually impairs the ability of the eye to focus properly, potentially causing poor vision. The front surface called the cornea and it's like a clear window to the eye.. The aim of corneal cross-linking is to strengthen the cornea by increasing the number of "anchors" that bond collagen fibers together. As the cornea becomes more irregular in shape, it causes progressive nearsightedness and irregular astigmatism to develop, creating additional problems with distorted and blurred vision. For the detection of early keratoconus, Placido disc–based topography has been supplanted by Scheimpflug tomography, which can map both the anterior and posterior corneal surfaces. SEE ALSO: Answers From An Eye Doctor About Keratoconus >. Accessed 8/27/2019. To decrease patient discomfort and mitigate these risks, researchers and clinicians are interested in a CXL protocol that leaves the epithelium intact while still adequately strengthening the cornea. A New Zealand team of researchers has developed a tissue-engineering approach to treating keratoconus. Corneal cross-linking is a treatment for an eye problem called keratoconus.. These high-water silicone hydrogel lenses can correct up to 20 (D) of nearsightedness or farsightedness and up to -12 D of astigmatism. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. Li Y, Chamberlain W, Tan O, et al. 1. With the epithelium-on method (also called transepithelial crosslinking), the corneal epithelium is left intact during the treatment. More by this author . While more study is needed, early results of a small study involving topography-guided conductive keratoplasty (CK) show this procedure might help smooth irregularities in the corneal surface. In 2016, however, the FDA approved cross-linking surgery as a treatment for keratoconus and recommended that a registry system should be set-up to evaluate the long-term treatment effect. Update on Keratoconus Treatment. Because of the precise nature of the back surface fit, high quality and individualized optics can be placed on the front surface of the device. © 2000-2020 AAV Media, LLC. Recent reports have confirmed greater patient comfort (per Ocular Surface Disease Index scores) and improved BCVA with epithelium-on, or epi-on, CXL, but the epi-off procedure is probably more effective at halting progressive ectasia for the long term.9 This appears to be the consensus of most published studies, although new formulations of riboflavin, techniques involving iontophoresis, and the use of oxygen goggles may improve results with epi-on CXL in the near future.10, A new strategy for maximizing both the effect of CXL and its visual outcomes is to apply customized UV-A irradiation patterns on the cornea. This article highlights promising recent advances in keratoconus management. Mark Lobanoff, MD. Optovue was the first manufacturer whose OCT technology gained FDA approval for epithelial thickness mapping. Research is driving promising advances in diagnosis and treatment. Intacs might delay but can't prevent a corneal transplant if keratoconus continues to progress. This technology allows the laser system to identify and target raised topographic features, such as an elevated cone, thereby normalizing the shape of an irregular keratoconic cornea to improve BCVA. The idea is to maximize the CXL effect in the weakest region of the cornea, usually inferiorly, and to apply weaker amounts of irradiation in concentric rings expanding out from the cone. Intacs ®, intrastromal corneal ring segments, were approved for keratoconus treatment in 2004.Previously, Intacs ® segments were used to treat low amounts of myopia (under -3.00). Tomographic and biomechanical Scheimpflug imaging for keratoconus characterization: a validation of current indices. Even after a transplant, you most likely will need glasses or contact lenses for clear vision. The aim of this procedure is to strengthen an already weak cornea by ‘cross linking’ the collagen fibres found in the cornea. 12. . 2019 Feb;97(1):e22-e35. The only FDA-approved medication to treat the progression of keratoconus is riboflavin 5´-phosphate ophthalmic solution. Risk factors for oxidative damage and weakening of the cornea include a genetic predisposition, explaining why keratoconus often affects more than one member of the same family. Glare and light sensitivity also may occur. He has pioneered treatments for keratoconus, participated ... Custom toric soft contacts for keratoconus are significantly more expensive than regular soft contacts, but vision insurance may cover some of the costs associated with contact lenses for keratoconus. Corneal crosslinking is a modern corneal scar treatment that can slow the progress of keratoconus. In this condition, the front part of your eye, called the cornea, thins out and gets weaker over time. Keratoconus - Causes, Symptoms and Treatment August 20, 2019 Keratoconus is an eye condition, where the cornea which is usually round and dome-shaped begins to … These lenses were designed specifically for keratoconus, and the central GP zone of the lens vaults over the cone-shaped cornea for increased comfort. Preoperative BCVA was 20/80. The traditional method is called “penetrating keratoplasty” (PK). Download PDF. Keratoconus. Get useful, helpful and relevant health + wellness information. In the United States, custom soft contacts that are available for the correction of keratoconus include: KeraSoft lenses (Bausch + Lomb). In the mildest form of keratoconus, eyeglasses or soft contact lenses may help. Keratoconic corneas have been found to be softer than healthy corneas, which is why CXL is used for stiffening the tissue to stabilize the disease. Using a combination of corneal crosslinking and Intacs implants also has demonstrated promising results for treating keratoconus. Two devices are available in the United States to measure corneal biomechanics: the Corvis ST (Oculus Optikgeräte) and the Ocular Response Analyzer (Reichert). Also, progressive mild to moderate keratoconus has been safely and successfully treated with a combination of corneal crosslinking and implantation of a toric phakic IOL. Fitting contact lenses on an eye with keratoconus often is challenging and time-consuming. Eyes with advanced keratoconus may require an advanced prosthetic scleral lens design. August 9, 2019 | By First Eye Care DFW. With epithelium-off crosslinking, the outer layer of the cornea (called the epithelium) is removed to allow entry of riboflavin, a type of B vitamin, into the cornea, which then is activated with UV light. Keratoconus is actually a disease of the surface of the eye. The market for keratoconus treatment was around USD 322.7 million in 2016 and is expected to reach USD 427.5 million by 2023 which is a projected CAGR of 4.1%. The original protocol for performing CXL focused solely on strengthening the cornea by forming bonds between corneal fibers. Keratoconus affects men and women equally, about 1 in 500 to 2,000 individuals overall, and 5-15% of individuals born with Down Syndrome. To treat keratoconus there are two corneal transplant methods. It is to be hoped that further studies with longer postoperative follow-up will clarify what combination of time and intensity provides the best outcomes. Steinberg J, Siebert M, Katz T, et al. The process begins with an EyePrint Impression, which captures the precise curvatures of the entire ocular surface. Comparison of standard and accelerated corneal cross-linking for the treatment of keratoconus: a meta-analysis Acta Ophthalmol . The risk information provided here is not comprehensive. As one would expect, the cohort in which both topographic and refractive error was treated had better UCVA and BCVA outcomes than the cohort limited to the treatment of topographic abnormalities.13. But as the disease progresses and the cornea thins and becomes increasingly more irregular in shape, glasses and regular soft contact lens designs no longer provide adequate vision correction. There are two versions of corneal crosslinking: epithelium-off and epithelium-on. However, most modern contacts — both GP and soft — typically have adequate oxygen permeability for a safe "piggyback" fit. This leads to a strengthening of the structure of the cornea. The UltraHealth and ClearKone hybrid contact lenses manufactured by SynergEyes combine a highly oxygen-permeable rigid center with a soft peripheral "skirt." More by this author . Stulting RD, Trattler WB, Woolfson JM, Rubinfield RS. Meanwhile, the National Keratoconus Foundation reports a link between allergies and keratoconus. Advantages include less risk of infection, less discomfort and one-day visual recovery. Treatments for progressive keratoconus include: This procedure, also called corneal collagen cross-linking or CXL, strengthens corneal tissue to halt bulging of the eye's surface in keratoconus. Hybrid contact lenses provide the crisp optics of a gas permeable contact lens and wearing comfort that rivals that of soft lenses, according to SynergEyes. We then use the Phorcides Analytical Software designed by Mark Lobanoff, MD, to help plan refractive topography-guided correction of the cornea. IVMED-80, a copper-based eye drop is also being researched for its effect on increasing lysyl oxidase activity and corneal stiffness. By contrast, in an ectatic cornea, the epithelial layer exhibits significant thinning over the cone (Figure 1), sometimes surrounded by a “doughnut” of thicker epithelium.¹ This epithelial masking effect on the anterior surface may explain in part why it is easier to detect early ectasia on the posterior surface. The last remedy to be considered may be a cornea transplant, also called a penetrating keratoplasty (PK or PKP). All RIghts Reserved • Privacy Policy. Often, keratoconic patients experience changes in their eyeglass prescription every time they visit their eye doctor. The maximum keratometry reading decreased from 54.61 D to 43.48 D, and corneal cylinder decreased from 7.46 D to 3.18 D. It is an exciting time to be managing patients with keratoconus in the United States. Ozgurhan E, Akcay B, Kurt T, Yildirim Y, Demirok A. Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area. Although the procedure halted keratoconic progression, it did not improve patients’ VA. Make sure your cross-linking is FDA-approved and covered by insurance. 4. In this case, eye drops containing low levels … Your doctor should monitor defects in the outermost corneal layer of the eye for resolution. It also is being investigated as a way to treat or prevent complications following LASIK or other vision correction surgery. fine white lines, dry eye, disruption of surface cells, eye pain, light sensitivity, reduced sharpness of vision, and blurred vision. In a first-ever collaboration, 4 supranational cornea societies joined forces in a complex, multistep process to develop the Global Consensus on Keratoconus and Ectatic Diseases. Keratoconus (ker-uh-toe-KOH-nus) occurs when your cornea — the clear, dome-shaped front surface of your eye — thins and gradually bulges outward into a cone shape.A cone-shaped cornea causes blurred vision and may cause sensitivity to light and glare. 3. Cifariello F, Minicucci M, Di Renzo F, et al. These larger lenses also are more stable than conventional gas permeable contact lenses, which move with each blink because they cover only a portion of the cornea. The surgical procedure takes only about 10 minutes. View PDF. This approach increases wearer comfort because the soft lens acts like a cushioning pad under the rigid GP lens. 73. As research advances, gold-standard technologies gradually change. The scanned data is then fed to a numerically controlled machining system to produce a lens that matches the impression exactly and therefore fits the individual cornea and sclera perfectly. Read more. Several studies show that Intacs can improve the best spectacle-corrected visual acuity (BSCVA) of a keratoconic eye by an average of two lines on a standard eye chart. Keratoconus KC is a condition of the eye which results in liberal thinning of the cornea. Other ocular side effects include inflammation, Cleveland Clinic is a non-profit academic medical center. Nattis A, Donnenfeld ED, Rosenberg E, Perry HD. New technologies and regulatory approvals have made the diagnosis and treatment of keratoconus an exciting field for ophthalmologists and optometrists alike. May 2019. Today, the treatment is widely covered by commercial insurance. Kanellopoulos A. It involves creating new links between the collagen fibers as well as making them thicker and shorter. Your eye care practitioner will monitor closely the fitting of "piggyback" contact lenses to make sure enough oxygen reaches the surface of your eye, which can be a problem when two lenses are worn on the same eye. The use of any drug or drugs other than Photrexa Viscous and Photrexa or any device other than the KXL System for corneal cross-linking is not FDA approved, except as part of an investigational new drug study. Combined wavefront-guided transepithelial photorefractive keratectomy and corneal crosslinking for visual rehabilitation in moderate keratoconus. It's the only keratoconus treatment proven to slow or stop the progression of the disease. Visual and keratometric outcomes of keratoconus patients after sequential corneal crosslinking and topography-guided surface ablation: Early United States experience. Studies have shown that both devices can differentiate normal from keratoconic corneas; the Corvis is able to do so in the absence of topographic or tomographic data.2-4 Further studies are being done to validate the recently developed Tomography and Biomechanical Index, which is a value combining Scheimpflug tomographic and biomechanical data for enhanced detection of ectasia.5. 8. Comparison of sequential vs same-day simultaneous collagen cross-linking and topography-guided PRK for treatment of keratoconus. The implants also have the advantage of being removable and exchangeable. Corneal crosslinking. In 2016, Avedro's corneal cross-linking procedure became the first and only FDA approved corneal cross-linking treatment for progressive keratoconus. Topography before (A) and after (B) treatment of the left eye in a patient with keratoconus. 10. Keratoconus Treatment. Seiler TG, Fischinger I, Koller T, et al. As access, insurance coverage, and use of these technologies improve, visual disability from keratoconus will be a rare occurrence in the near future. Are polarized sunglasses good for night driving? The risk for keratoconus is increased in people who have asthma (as reported by the American Optometric Association).More than 23 million people in the US are living with asthma, and the onset of this health disorder often begins in childhood. 2020;61:2587. GP lenses vault over the cornea, replacing its irregular shape with a smooth, uniform refracting surface to improve vision. Contact lenses or glasses can be used to help correct vision, while FDA-approved corneal cross-linking is a non-invasive treatment to slow or halt keratoconus that is progressive. How older drivers can improve their driving at night, Improve your driving at night: With tips on glasses and lenses. What’s the difference between an HSA and FSA? Corneal crosslinking without epithelial removal. Join our community to receive newsletters and offers. Research is driving promising advances in diagnosis and treatment. The FDA approval of corneal cross-linking (CXL) has ignited further research into how best to halt ectatic vision loss and how to recover visual acuity through combined procedures. Tear fluid analysis for detecting biomarkers for keratoconus and targeted treatments such as Cyclosporine A to reduce MMP-9 and inflammatory cytokine levels are being researched to decrease progression. Intacs (Addition Technology) are FDA-approved clear, arc-shaped corneal inserts that are surgically positioned within the peripheral cornea to reshape the front surface of the eye for clearer vision. It's a non-invasive procedure that strengthens the cornea by "cross-linking" the cornea's collagen fibres through the application of Riboflavin drops and exposure to UV-A light. You optician will be able to advise on what’s best for you. 1. All About Vision and AllAboutVision.com are registered trademarks of AAV Media, LLC. An important step in standard CXL is removing the epithelium in order to maximize riboflavin penetration and oxygen availability, both of which are critical to the CXL photochemical reaction. "The EyePrint is like a fingerprint—it's completely individual," says EyePrint developer Dr. Christine Sindt, Clinical Associate Professor of Ophthalmology and Visual Sciences at University of Iowa. In March, Carl Zeiss Meditec gained FDA approval for epithelial thickness mapping with its Cirrus HD-OCT. What do the numbers on your eyeglass frames mean? This system uses proprietary Elevation Specific Technology to exactly match the unique irregularities of each individual eye. Advertising on our site helps support our mission. For keratoconus, this method involves placing a soft contact lens, such as one made of silicone hydrogel, over the eye and then fitting a GP lens over the soft lens. Medicaid: Eligibility and Vision Benefits. enews. (Diagram: Boxer Wachler Vision Institute). Paul Hammond, OD, FAAO. Keratoconus can occur in one or both eyes and often begins during a person's teens or early 20s. Invest Ophthalmol Vis Sci. The EyePrintPRO can only be fit by doctors who undergo specific training and certification. IVMED 80 eye drops for treatment of keratoconus in patients -Phase 1/2a. 11. Explore further Genetic factors behind eye disorder identified With this strategy, known as epi-off CXL, come patient discomfort and the risks of delayed epithelial healing, infection, sterile infiltrates, and stromal haze. We perform accelerated CXL with pulsed 18 mW UV-A delivery and allow oxygen to reenter the cornea between UV-A treatments (2 minutes on, 1 minute off, 1 minute on, 1 minute off, 2 minutes on). The popularity of and evidence for corneal biomechanical measurements for detecting glaucoma risk are growing. Dr. Kanellopoulos found that both methods were safe when the ablation depth was limited to 50 µm, with no patients showing disease progression, but he reported that the simultaneous method resulted in better final visual acuity results.12, Earlier this year, Nattis and colleagues published a study in which TG-PRK was used not only to normalize topography but also to treat refractive error beyond the 50-µm threshold.13 In the study, patients underwent CXL followed by TG-PRK 30 months later on average. 2. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088. With the sequential approach, CXL is followed 1 to 2 years later by topography-guided PRK (TG-PRK). 7. Can coronavirus (or a cold or the flu) cause pink eye? IVMED-80, a twice-daily eye drop for the treatment of keratoconus in development by iVeena Delivery Systems, was recently granted orphan drug designation by the FDA. For progressive keratoconus, only Avedro's corneal cross-linking procedure is FDA approved and widely covered by insurance. A potential solution, therefore, would be to combine laser ablation with a strengthening procedure such as CXL. Example of epithelial mapping of a keratoconic cornea. Ulcerative keratitis, a potentially serious eye infection, can occur. Click here to view your insurance policy. Toker E, Çerman E, Özcan DÖ, Seferoglu ÖB. Gore DM, Leucci MT, Anand V, et al. Keratoconus treatment can include eyeglasses, special hard con Keratoconus diagnosis include a comprehensive eye exam and tests to determine your corneal shape. Corneal crosslinking may reduce significantly the need for corneal transplants among keratoconus patients. Investigators have found that posterior corneal changes are an early marker for ectasia, preceding changes on the anterior surface. In this surgery, the ophthalmologist removes full-thickness central cornea and replaces it with donor tissue, known as a “corneal button.” These measurements can also provide valuable information on a patient’s risk of ectasia. Doctors then send the resulting impression to an EyePrint lab for 3-D scanning. Both technologies facilitate the identification of biomechanically at-risk corneas before any decompensation begins to alter corneal curvature. These lenses are made-to-order based on detailed measurements of the person's keratoconic eye(s) and may be more comfortable than gas permeable lenses (GPs) or hybrid contact lenses for some wearers. You can expect frequent return visits to your eye care provider so he or she can fine-tune the fit and your prescription, especially if your keratoconus continues to progress. At our clinic, we have been developing a Minneapolis epi-off protocol. Glasses or contact lenses can help with mild cases.
