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. Get useful, helpful and relevant health + wellness information. Keratoconus can occur in one or both eyes and often begins during a person's teens or early 20s. Combined wavefront-guided transepithelial photorefractive keratectomy and corneal crosslinking for visual rehabilitation in moderate 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. 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. 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. Often, keratoconic patients experience changes in their eyeglass prescription every time they visit their eye doctor. 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. Example of epithelial mapping of a keratoconic cornea. Figure 1. Other ocular side effects include inflammation, In this case, eye drops containing low levels … Mark Lobanoff, MD. Gore DM, Leucci MT, Anand V, et al. Customized corneal cross-linking: one-year results. More by this author . With the sequential approach, CXL is followed 1 to 2 years later by topography-guided PRK (TG-PRK). The aim of this procedure is to strengthen an already weak cornea by ‘cross linking’ the collagen fibres found in 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. Li Y, Chamberlain W, Tan O, et al. Recently, contact lens manufacturers have introduced custom soft contact lenses specially designed to correct mild-to-moderate keratoconus. A potential solution, therefore, would be to combine laser ablation with a strengthening procedure such as CXL. Comparison of standard and accelerated corneal cross-linking for the treatment of keratoconus: a meta-analysis Acta Ophthalmol . 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. IVMED 80 eye drops for treatment of keratoconus in patients -Phase 1/2a. The UltraHealth and ClearKone hybrid contact lenses manufactured by SynergEyes combine a highly oxygen-permeable rigid center with a soft peripheral "skirt." Join our community to receive newsletters and offers. Accelerated corneal collagen cross-linking in thin keratoconic corneas. It also is being investigated as a way to treat or prevent complications following LASIK or other vision correction surgery. 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 … With the epithelium-on method (also called transepithelial crosslinking), the corneal epithelium is left intact during the treatment. Vinciguerra R, Ambrósio R, Roberts C, Azzolini C, Vinciguerra P. Biomechanical characterization of subclinical keratoconus without topographic or tomographic abnormalities. 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. 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. However, most modern contacts — both GP and soft — typically have adequate oxygen permeability for a safe "piggyback" fit. As research advances, gold-standard technologies gradually change. Advertising on our site helps support our mission. The EyePrintPRO can only be fit by doctors who undergo specific training and certification. 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. 2020;61:2587. 2019 Feb;97(1):e22-e35. Keratoconus affects men and women equally, about 1 in 500 to 2,000 individuals overall, and 5-15% of individuals born with Down Syndrome. (Diagram: Boxer Wachler Vision Institute). Brian Boxer Wachler, MD, is an ophthalmologist and refractive surgeon at the Boxer Wachler Vision Institute in Beverly Hills, Calif. 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). Wollensak G, Spoerl E, Seiler T. Riboflavin/ultraviolet-A-induced collagen crosslinking for the treatment of keratoconus. (Glaukos recently acquired Avedro.). Visual and keratometric outcomes of keratoconus patients after sequential corneal crosslinking and topography-guided surface ablation: Early United States experience. Explore further Genetic factors behind eye disorder identified Since then, the procedure has been completed more than 18,000 times at more than 300 practices nationwide. 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. 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 eventually impairs the ability of the eye to focus properly, potentially causing poor vision. This procedure, also called corneal collagen cross-linking or CXL, strengthens corneal tissue to halt bulging of the eye's surface in keratoconus. Efficacy of different accelerated corneal crosslinking protocols for progressive keratoconus. GP lenses vault over the cornea, replacing its irregular shape with a smooth, uniform refracting surface to improve vision. Corneal crosslinking may reduce significantly the need for corneal transplants among keratoconus patients. Share: Link has been copied to your clipboard. In 2003, WaveLight developed technology to perform topography-guided excimer laser treatment. The only FDA-approved medication to treat the progression of keratoconus is riboflavin 5´-phosphate ophthalmic solution. Investigators have found that posterior corneal changes are an early marker for ectasia, preceding changes on the anterior surface. All About Vision and AllAboutVision.com are registered trademarks of AAV Media, LLC. 8. 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. Eyeglass temples: How do you know if they're the right length? 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. Keratoconus usually affects both eyes and generally begins to first affect people ages 10 to 25. 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. Steinberg J, Siebert M, Katz T, et al. IVMED-80, a copper-based eye drop is also being researched for its effect on increasing lysyl oxidase activity and corneal stiffness. Researchers have found that epithelial thickness is fairly uniform from the center to the periphery in healthy corneas. It's the only keratoconus treatment proven to slow or stop the progression of the disease. doi: 10.1111/aos.13814. These measurements can also provide valuable information on a patient’s risk of ectasia. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088. NovaKone lenses (Bausch + Lomb). 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. New technologies are improving our ability to diagnose keratoconus earlier than ever before and facilitating visual recovery with remarkable results. 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. Kanellopoulos A. Using a combination of corneal crosslinking and Intacs implants also has demonstrated promising results for treating keratoconus. Accessed 8/27/2019. 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. You are encouraged to report all side effects to the FDA. In this surgery, the ophthalmologist removes full-thickness central cornea and replaces it with donor tissue, known as a “corneal button.” Ulcerative keratitis, a potentially serious eye infection, can occur. Research is driving promising advances in diagnosis and treatment. Update on Keratoconus Treatment. With this strategy, known as epi-off CXL, come patient discomfort and the risks of delayed epithelial healing, infection, sterile infiltrates, and stromal haze. Click here to find a cornea specialist near you. 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. As access, insurance coverage, and use of these technologies improve, visual disability from keratoconus will be a rare occurrence in the near future. 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. Both lenses have a very wide range of fitting parameters for a customized fit and are larger in diameter than regular soft lenses for greater stability on a keratoconic eye. 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. 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. More by this author . Because simultaneous treatments were found to produce the best results, we use the following regimen. Cifariello F, Minicucci M, Di Renzo F, et al. Keratoconus Treatment Options. For progressive keratoconus, only Avedro's corneal cross-linking procedure is FDA approved and widely covered by insurance. The aim of corneal cross-linking is to strengthen the cornea by increasing the number of "anchors" that bond collagen fibers together. To decrease patient discomfort and mitigate risks, epi-on CXL protocols that leave the epithelium intact while still adequately strengthening the cornea are of interest. At A Glance. Advertising on our site helps support our mission. 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. New technologies and regulatory approvals have made the diagnosis and treatment of keratoconus an exciting field for ophthalmologists and optometrists alike. 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. Even after a transplant, you most likely will need glasses or contact lenses for clear vision. While keratoconus can be a challenging condition, it can be managed effectively when detected early. In March, Carl Zeiss Meditec gained FDA approval for epithelial thickness mapping with its Cirrus HD-OCT. 5. The best treatment for keratoconus will depend on its severity and how quickly it is progressing. 10. Paul Hammond, OD, FAAO. It is a photoenhancer indicated … [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. 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%. Figure 2. What do the numbers on your eyeglass frames mean? 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. There are Many Treatment Options for Keratoconus. The surgical procedure takes only about 10 minutes. 6. 1. Keratoconus is a progressive eye condition that affects the cornea, causing it to bulge out. This approach increases wearer comfort because the soft lens acts like a cushioning pad under the rigid GP lens. Are polarized sunglasses good for night driving? 1. Fitting contact lenses on an eye with keratoconus often is challenging and time-consuming. Keratoconus treatment can include eyeglasses, special hard con Keratoconus diagnosis include a comprehensive eye exam and tests to determine your corneal shape. Preoperative BCVA was 20/80. Are contact lenses a good choice for kids? 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. 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. Keratoconus. Tomographic and biomechanical Scheimpflug imaging for keratoconus characterization: a validation of current indices. Keratoconus KC is a condition of the eye which results in liberal thinning of the cornea. Topography before (A) and after (B) treatment of the left eye in a patient with keratoconus. It involves creating new links between the collagen fibers as well as making them thicker and shorter. 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. Read more. Intacs may be needed when keratoconus patients no longer can obtain functional vision with contact lenses or eyeglasses. This imbalance makes the cornea more susceptible to oxidative damage from compounds called free radicals, causing it to weaken and bulge forward. enews. The Avedro KXL system is indicated for treatment of progressive keratoconus in patients ages 14 and older by first debriding the corneal epithelium. We then use the Phorcides Analytical Software designed by Mark Lobanoff, MD, to help plan refractive topography-guided correction of the cornea. One example are lenses made with the EyePrintPRO process (EyePrint Prosthetics). We do not endorse non-Cleveland Clinic products or services. The most common ocular side effect is haze. In the United States, custom soft contacts that are available for the correction of keratoconus include: KeraSoft lenses (Bausch + Lomb). 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. The original protocol for performing CXL focused solely on strengthening the cornea by forming bonds between corneal fibers. The popularity of and evidence for corneal biomechanical measurements for detecting glaucoma risk are growing. 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. This leads to a strengthening of the structure of the cornea. Scleral lenses cover a larger portion of the sclera, whereas semi-scleral lenses cover a smaller area. 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. Available Treatment Options. 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 traditional method is called “penetrating keratoplasty” (PK). The front surface called the cornea and it's like a clear window to the eye.. What’s the difference between an HSA and FSA? 3. 12. Researchers are investigating ways to combine CXL with excimer laser ablation to not only strengthen ectatic corneas but also improve BCVA. The risk information provided here is not comprehensive. This is a non-invasive treatment for patients with 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. Subclinical keratoconus detection by pattern analysis of corneal and epithelial thickness maps with optical coherence tomography. 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. 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. Although the procedure halted keratoconic progression, it did not improve patients’ VA. You optician will be able to advise on what’s best for you. 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. 4. 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. Corneal crosslinking is a modern corneal scar treatment that can slow the progress of keratoconus. A topographic "map" created by computer imaging of the eye's surface helps create individualized treatment plans. This cone shape deflects light as it enters the eye on its way to the light-sensitive retina, causing distorted vision. 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. Cleveland Clinic is a non-profit academic medical center. Invest Ophthalmol Vis Sci. How older drivers can improve their driving at night, Improve your driving at night: With tips on glasses and lenses. The implants also have the advantage of being removable and exchangeable. A New Zealand team of researchers has developed a tissue-engineering approach to treating keratoconus. The first is the Corneal Cross Linking procedure, also known as CXL. Keratoconus is a progressive eye disease in which the normally round cornea thins and begins to bulge into a cone-like shape. 2. The aim of corneal cross-linking is to strengthen the cornea by increasing the number of "anchors" that bond collagen fibers together. A recent addition to the analysis of corneal curvature involves mapping the thickness of the corneal epithelium with OCT. Treatment options for keratoconus In the early stages of keratoconus, corrective glasses or contact lenses can help the patient. Keratoconus Treatment. Doctors then send the resulting impression to an EyePrint lab for 3-D scanning. A. John Kanellopoulos, MD, developed the Athens protocol and has investigated the safety and efficacy of both sequential and simultaneous treatments. 7. There are two versions of corneal crosslinking: epithelium-off and epithelium-on. 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. Cleveland Clinic is a non-profit academic medical center. © 2000-2020 AAV Media, LLC. We plan to publish our 2-year results soon, but outcomes so far are promising, with excellent acuity improvements and equally good reduction of maximum keratometry compared with recently published studies (Figure 2). 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. enews. To treat keratoconus there are two corneal transplant methods. Molokhia S, Muddana SK, Hauritz H, et al. 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. 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. Epi-off versus epi-on corneal collagen cross-linking in keratoconus patients: a comparative study through 2-year follow-up. Vinciguerra R, Ambrósio R, Elsheikh A, Roberts C, Lopes B, Morenghi E, Azzolini C, Vinciguerra P. Detection of keratoconus with a new biomechanical index. fine white lines, dry eye, disruption of surface cells, eye pain, light sensitivity, reduced sharpness of vision, and blurred vision. 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. OCT epithelial mapping can provide supplemental information that should improve early detection of subclinical keratoconus. Make sure your cross-linking is FDA-approved and covered by insurance. What happens to FSA dollars at the end of the year? Hallahan KM, Sinha Roy A, Ambrósio R Jr, Salomao M, Dupps WJ Jr. Discriminant value of custom ocular response analyzer waveform derivatives in keratoconus. Get useful, helpful and relevant health + wellness information. 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. These lenses were designed specifically for keratoconus, and the central GP zone of the lens vaults over the cone-shaped cornea for increased comfort. As keratoconus advances, the corneal surface becomes increasingly irregular and these options do not help adequately. 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. Retinal detachment: Symptoms, causes and treatment. The process begins with an EyePrint Impression, which captures the precise curvatures of the entire ocular surface. Advantages include less risk of infection, less discomfort and one-day visual recovery. "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. 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. Tissue engineering is the science of improving or replacing biological tissue using various growth factors. 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. With the simultaneous approach, TG-PRK is followed immediately by CXL. The last remedy to be considered may be a cornea transplant, also called a penetrating keratoplasty (PK or PKP). 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. This system uses proprietary Elevation Specific Technology to exactly match the unique irregularities of each individual eye. 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. OCT epithelial mapping will not replace corneal tomography, but it can provide supplemental information that should improve early detection of subclinical keratoconus. Research is driving promising advances in diagnosis and treatment. Toker E, Çerman E, Özcan DÖ, Seferoglu ÖB. We do not endorse non-Cleveland Clinic products or services. At our clinic, we have been developing a Minneapolis epi-off protocol. 11. Glasses or contact lenses can help with mild cases. Corneal crosslinking without epithelial removal. 72. 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. He has pioneered treatments for keratoconus, participated ... These high-water silicone hydrogel lenses can correct up to 20 (D) of nearsightedness or farsightedness and up to -12 D of astigmatism. Glare and light sensitivity also may occur. . Postoperative UCVA was 20/25. This article highlights promising recent advances in keratoconus management. Click here to view your insurance policy. 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. Follow-Up will clarify what combination of corneal cross-linking for the treatment of keratoconus, eyeglasses or soft contact can. Corneal changes are an early marker for ectasia, preceding changes on the anterior surface improving or replacing tissue.
