Customized corneal cross-linking: one-year results. 2020;61:2587. Efficacy of different accelerated corneal crosslinking protocols for progressive keratoconus. Figure 1. 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. 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. Advantages include less risk of infection, less discomfort and one-day visual recovery. This eventually impairs the ability of the eye to focus properly, potentially causing poor vision. [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. enews. Using a combination of corneal crosslinking and Intacs implants also has demonstrated promising results for treating keratoconus. This leads to a strengthening of the structure of the cornea. 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. Treatment options for keratoconus In the early stages of keratoconus, corrective glasses or contact lenses can help the patient. 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. Both technologies facilitate the identification of biomechanically at-risk corneas before any decompensation begins to alter corneal curvature. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. A topographic "map" created by computer imaging of the eye's surface helps create individualized treatment plans. 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. Cifariello F, Minicucci M, Di Renzo F, et al. Cleveland Clinic is a non-profit academic medical center. 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 might delay but can't prevent a corneal transplant if keratoconus continues to progress. 8. 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. The traditional method is called “penetrating keratoplasty” (PK). More by this author . Optovue was the first manufacturer whose OCT technology gained FDA approval for epithelial thickness mapping. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088. 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. Tomographic and biomechanical Scheimpflug imaging for keratoconus characterization: a validation of current indices. 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. The process begins with an EyePrint Impression, which captures the precise curvatures of the entire ocular surface. 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. It's the only keratoconus treatment proven to slow or stop the progression of the disease. Keratoconus Treatment. A. John Kanellopoulos, MD, developed the Athens protocol and has investigated the safety and efficacy of both sequential and simultaneous treatments. Keratoconus Treatment. Research is driving promising advances in diagnosis and treatment. Since then, the procedure has been completed more than 18,000 times at more than 300 practices nationwide. Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area. We do not endorse non-Cleveland Clinic products or services. As access, insurance coverage, and use of these technologies improve, visual disability from keratoconus will be a rare occurrence in the near future. Wollensak G, Spoerl E, Seiler T. Riboflavin/ultraviolet-A-induced collagen crosslinking for the treatment of keratoconus. Your doctor should monitor defects in the outermost corneal layer of the eye for resolution. Click here to find a cornea specialist near you. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision. 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. 73. The aim of this procedure is to strengthen an already weak cornea by ‘cross linking’ the collagen fibres found in the cornea. 1. Even after a transplant, you most likely will need glasses or contact lenses for clear vision. 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. 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. This procedure, also called corneal collagen cross-linking or CXL, strengthens corneal tissue to halt bulging of the eye's surface in keratoconus. Vinciguerra R, Ambrósio R, Roberts C, Azzolini C, Vinciguerra P. Biomechanical characterization of subclinical keratoconus without topographic or tomographic abnormalities. Paul Hammond, OD, FAAO. The most common ocular side effect is haze. These medium-water hydrogel lenses can correct up to 30 D of nearsightedness or farsightedness and up to -10 D of astigmatism. The popularity of and evidence for corneal biomechanical measurements for detecting glaucoma risk are growing. Seiler TG, Fischinger I, Koller T, et al. Recently, contact lens manufacturers have introduced custom soft contact lenses specially designed to correct mild-to-moderate keratoconus. New technologies are improving our ability to diagnose keratoconus earlier than ever before and facilitating visual recovery with remarkable results. What happens to FSA dollars at the end of the year? While keratoconus can be a challenging condition, it can be managed effectively when detected early. 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. Kanellopoulos A. August 9, 2019 | By First Eye Care DFW. doi: 10.1111/aos.13814. 1. Riboflavin 5’ … 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 … Keratoconus affects men and women equally, about 1 in 500 to 2,000 individuals overall, and 5-15% of individuals born with Down Syndrome. Other ocular side effects include inflammation, Make sure your cross-linking is FDA-approved and covered by insurance. Research is driving promising advances in diagnosis and treatment. OCT epithelial mapping will not replace corneal tomography, but it can provide supplemental information that should improve early detection of subclinical keratoconus. 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. Steinberg J, Siebert M, Katz T, et al. 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. Glasses or contact lenses can help with mild cases. (Diagram: Boxer Wachler Vision Institute). GP lenses vault over the cornea, replacing its irregular shape with a smooth, uniform refracting surface to improve vision. The EyePrintPRO can only be fit by doctors who undergo specific training and certification. Keratoconus Diagnosis and Treatment - American Academy of Ophthalmology Keratoconus diagnosis include a comprehensive eye exam and tests to determine your corneal shape. This is a non-invasive treatment for patients with keratoconus. Get useful, helpful and relevant health + wellness information. 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. With the epithelium-on method (also called transepithelial crosslinking), the corneal epithelium is left intact during the treatment. Eyeglass temples: How do you know if they're the right length? Subclinical keratoconus detection by pattern analysis of corneal and epithelial thickness maps with optical coherence tomography. 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. 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. Comparison of sequential vs same-day simultaneous collagen cross-linking and topography-guided PRK for treatment of keratoconus. With the simultaneous approach, TG-PRK is followed immediately by CXL. Corneal crosslinking without epithelial removal. He has pioneered treatments for keratoconus, participated ... Nattis A, Donnenfeld ED, Rosenberg E, Perry HD. May 2019. This system uses proprietary Elevation Specific Technology to exactly match the unique irregularities of each individual eye. Gore DM, Leucci MT, Anand V, et al. 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. enews. Currently, the only corneal cross-linking platform that is FDA-approved for the treatment of progressive keratoconus in the U.S. is epithelium-off cross-linking performed with a Glaukos KXL System and proprietary Photrexa and Photrexa Viscous riboflavin solutions. Today, the treatment is widely covered by commercial insurance. 13. Ozgurhan E, Akcay B, Kurt T, Yildirim Y, Demirok A. (Glaukos recently acquired Avedro.). Brian Boxer Wachler, MD, is an ophthalmologist and refractive surgeon at the Boxer Wachler Vision Institute in Beverly Hills, Calif. 10. IVMED 80 eye drops for treatment of keratoconus in patients -Phase 1/2a. Stulting RD, Trattler WB, Woolfson JM, Rubinfield RS. 6. 3. New technologies and regulatory approvals have made the diagnosis and treatment of keratoconus an exciting field for ophthalmologists and optometrists alike. Can coronavirus (or a cold or the flu) cause pink eye? 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. It involves creating new links between the collagen fibers as well as making them thicker and shorter. Retinal detachment: Symptoms, causes and treatment. Comparison of standard and accelerated corneal cross-linking for the treatment of keratoconus: a meta-analysis Acta Ophthalmol . Eyes with advanced keratoconus may require an advanced prosthetic scleral lens design. One example are lenses made with the EyePrintPRO process (EyePrint Prosthetics). Cleveland Clinic is a non-profit academic medical center. At our clinic, we have been developing a Minneapolis epi-off protocol. To learn more, talk to your healthcare provider. Toker E, Çerman E, Özcan DÖ, Seferoglu ÖB. Tell your healthcare provider if you are pregnant or plan to become pregnant. 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). With the sequential approach, CXL is followed 1 to 2 years later by topography-guided PRK (TG-PRK). 72. Investigators have found that posterior corneal changes are an early marker for ectasia, preceding changes on the anterior surface. We do not endorse non-Cleveland Clinic products or services. OCT epithelial mapping can provide supplemental information that should improve early detection of subclinical keratoconus. Tissue engineering is the science of improving or replacing biological tissue using various growth factors. The original protocol for performing CXL focused solely on strengthening the cornea by forming bonds between corneal fibers. 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. Molokhia S, Muddana SK, Hauritz H, et al. Download PDF. 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. In 2016, Avedro's corneal cross-linking procedure became the first and only FDA approved corneal cross-linking treatment for progressive keratoconus. 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. How older drivers can improve their driving at night, Improve your driving at night: With tips on glasses and lenses. 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). To treat keratoconus there are two corneal transplant methods. 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. 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. fine white lines, dry eye, disruption of surface cells, eye pain, light sensitivity, reduced sharpness of vision, and blurred vision. Epi-off versus epi-on corneal collagen cross-linking in keratoconus patients: a comparative study through 2-year follow-up. 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. 2019 Feb;97(1):e22-e35. 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. There are two versions of corneal crosslinking: epithelium-off and epithelium-on. Medicaid: Eligibility and Vision Benefits. Meanwhile, the National Keratoconus Foundation reports a link between allergies and keratoconus. Postoperative UCVA was 20/25. Read more. Advertising on our site helps support our mission. 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%. Keratoconus. You are encouraged to report all side effects to the FDA. You optician will be able to advise on what’s best for you. 9. 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. What do the numbers on your eyeglass frames mean? 4. All About Vision and AllAboutVision.com are registered trademarks of AAV Media, LLC. 12. 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. As keratoconus advances, the corneal surface becomes increasingly irregular and these options do not help adequately. Researchers are investigating ways to combine CXL with excimer laser ablation to not only strengthen ectatic corneas but also improve BCVA. 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 UltraHealth and ClearKone hybrid contact lenses manufactured by SynergEyes combine a highly oxygen-permeable rigid center with a soft peripheral "skirt." © 2000-2020 AAV Media, LLC. As research advances, gold-standard technologies gradually change. 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. Figure 2. Mark Lobanoff, MD. 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. 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 … Preoperative BCVA was 20/80. Often, keratoconic patients experience changes in their eyeglass prescription every time they visit their eye doctor. Are polarized sunglasses good for night driving? This imbalance makes the cornea more susceptible to oxidative damage from compounds called free radicals, causing it to weaken and bulge forward. Vinciguerra R, Ambrósio R, Elsheikh A, Roberts C, Lopes B, Morenghi E, Azzolini C, Vinciguerra P. Detection of keratoconus with a new biomechanical index. Keratoconus Treatment Options. This approach increases wearer comfort because the soft lens acts like a cushioning pad under the rigid GP lens. 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. 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. Get useful, helpful and relevant health + wellness information. Combined wavefront-guided transepithelial photorefractive keratectomy and corneal crosslinking for visual rehabilitation in moderate keratoconus. 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. Keratoconus usually affects both eyes and generally begins to first affect people ages 10 to 25. 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. The last remedy to be considered may be a cornea transplant, also called a penetrating keratoplasty (PK or PKP). 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. 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. Accelerated corneal collagen cross-linking in thin keratoconic corneas. Explore further Genetic factors behind eye disorder identified 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. 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. 7. In this case, eye drops containing low levels … In 2003, WaveLight developed technology to perform topography-guided excimer laser treatment. Photrexa Viscous® (riboflavin 5’-phosphate in 20% dextran ophthalmic solution) and Photrexa® (riboflavin 5’-phosphate ophthalmic solution) are used with the KXL®System in corneal cross-linking to treat eyes in which the cornea, the clear dome shaped surface that covers the front of the eye, has been weakened from the progression of the disease keratoconus or following refractive surgery, a method for correcting or improving your vision. A recent addition to the analysis of corneal curvature involves mapping the thickness of the corneal epithelium with OCT. In this surgery, the ophthalmologist removes full-thickness central cornea and replaces it with donor tissue, known as a “corneal button.” This article highlights promising recent advances in keratoconus management. Two devices are available in the United States to measure corneal biomechanics: the Corvis ST (Oculus Optikgeräte) and the Ocular Response Analyzer (Reichert). Keratoconus KC is a condition of the eye which results in liberal thinning of the cornea. These high-water silicone hydrogel lenses can correct up to 20 (D) of nearsightedness or farsightedness and up to -12 D of astigmatism. View PDF. We then use the Phorcides Analytical Software designed by Mark Lobanoff, MD, to help plan refractive topography-guided correction of the cornea. 5. IVMED-80, a copper-based eye drop is also being researched for its effect on increasing lysyl oxidase activity and corneal stiffness. All RIghts Reserved • Privacy Policy. 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. 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. Corneal crosslinking may reduce significantly the need for corneal transplants among keratoconus patients. 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. Topography before (A) and after (B) treatment of the left eye in a patient with keratoconus. Are contact lenses a good choice for kids? A potential solution, therefore, would be to combine laser ablation with a strengthening procedure such as CXL. In this condition, the front part of your eye, called the cornea, thins out and gets weaker over time. A New Zealand team of researchers has developed a tissue-engineering approach to treating keratoconus. Researchers have found that epithelial thickness is fairly uniform from the center to the periphery in healthy corneas. 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. The surgical procedure takes only about 10 minutes. Go to www.livingwithkeratoconus.com/ to obtain the FDA-approved product labeling. 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). Fitting contact lenses on an eye with keratoconus often is challenging and time-consuming. 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. It is a photoenhancer indicated … Corneal crosslinking. Join our community to receive newsletters and offers. Corneal cross-linking is a treatment for an eye problem called keratoconus.. In March, Carl Zeiss Meditec gained FDA approval for epithelial thickness mapping with its Cirrus HD-OCT. The front surface called the cornea and it's like a clear window to the eye.. NovaKone lenses (Bausch + Lomb). These lenses were designed specifically for keratoconus, and the central GP zone of the lens vaults over the cone-shaped cornea for increased comfort. Keratoconus is actually a disease of the surface of the eye. . For progressive keratoconus, only Avedro's corneal cross-linking procedure is FDA approved and widely covered by insurance. Hallahan KM, Sinha Roy A, Ambrósio R Jr, Salomao M, Dupps WJ Jr. Discriminant value of custom ocular response analyzer waveform derivatives in keratoconus. 11. There are Many Treatment Options for Keratoconus. SEE ALSO: Answers From An Eye Doctor About Keratoconus >. 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. 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. To learn more and to find an eye doctor who prescribes and fit these prosthetic lenses, visit the EyePrint Prosthetics website. Accessed 8/27/2019. Glare and light sensitivity also may occur. Share: Link has been copied to your clipboard. The only FDA-approved medication to treat the progression of keratoconus is riboflavin 5´-phosphate ophthalmic solution. More by this author . 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. The aim of corneal cross-linking is to strengthen the cornea by increasing the number of "anchors" that bond collagen fibers together. Keratoconus can occur in one or both eyes and often begins during a person's teens or early 20s. Although the procedure halted keratoconic progression, it did not improve patients’ VA.
