Is Keratoconus Considered a Disability?

Understanding Keratoconus and How It Affects Your Vision

Understanding Keratoconus and How It Affects Your Vision

If you have been diagnosed with keratoconus, you already know that something has changed in the way you see the world. Keratoconus is a progressive eye condition in which the cornea, the clear front surface of your eye, thins and bulges outward into a cone-like shape. This irregular curvature bends light unevenly as it enters the eye, producing distorted and blurry vision that standard glasses or soft contact lenses often cannot fully correct. The condition creates high levels of astigmatism, which means the eye focuses light at multiple points instead of one, along with increasing nearsightedness.

The visual problems caused by keratoconus go well beyond simple blurriness. You may notice ghosting or double images, significant glare and halos around lights, difficulty reading or working on screens, and trouble driving at night. These symptoms can shift as the corneal shape continues to change, making it hard to maintain consistent visual correction even with updated prescriptions. Many patients describe the frustration of seeing well one day and struggling the next.

Keratoconus typically begins during the teenage years or early twenties and may continue to worsen for one to two decades before stabilizing. The rate of progression varies from person to person. Some patients experience only mild corneal irregularity that remains manageable with specialty lenses, while others develop rapid thinning and scarring that severely reduce visual clarity. Factors such as chronic eye rubbing, allergic eye disease, and genetic predisposition can speed up the condition. You can learn more about the full range of signs and management approaches on our page about keratoconus symptoms, treatment, and cost.

When Keratoconus May Qualify as a Disability

When Keratoconus May Qualify as a Disability

Keratoconus is not automatically classified as a disability. Whether it qualifies depends on the severity of your vision loss and how much it limits your ability to work or perform daily tasks. In the United States, a person is considered legally blind if their best-corrected visual acuity in the better-seeing eye is 20/200 or worse, or if their visual field is 20 degrees or less. If keratoconus has progressed to the point where specialty contact lenses, corneal cross-linking, or other treatments cannot bring your corrected vision above 20/200, you would meet the Social Security Administration (SSA) listing for loss of visual acuity.

Many keratoconus patients do not meet the strict legal blindness criteria but still experience vision loss that prevents them from working. In these cases, the SSA evaluates your claim through what is called a medical-vocational allowance. This process considers your remaining visual abilities alongside your age, education, work history, and transferable skills. If the agency determines that your symptoms, such as unstable vision, severe glare sensitivity, or inability to focus for sustained periods, rule out all types of gainful employment, your claim may be approved even without meeting the 20/200 threshold.

The Americans with Disabilities Act (ADA) defines disability as a physical or mental impairment that substantially limits one or more major life activities, including seeing. If keratoconus substantially limits your vision, you may be entitled to reasonable workplace accommodations such as adjusted lighting, screen magnification software, modified duties, or flexible scheduling for medical appointments. You do not need to be legally blind to qualify for ADA protections. Employers with 15 or more employees are required to provide these accommodations unless doing so would cause undue hardship.

Veterans with service-connected keratoconus may qualify for disability compensation through the Department of Veterans Affairs. The VA rates keratoconus under Diagnostic Code 6035 using the General Rating Formula for Diseases of the Eye. Depending on the severity of your vision impairment and treatment frequency, you may receive a rating of 10 percent, 20 percent, 40 percent, or 60 percent, with corresponding monthly compensation.

How to Apply for Disability Benefits

Building a strong disability claim requires thorough medical documentation. The SSA will review your records for objective evidence of visual impairment. Your documentation should include the following:

  • Best-corrected visual acuity measurements for each eye
  • Corneal topography or tomography maps showing the degree of corneal irregularity
  • Slit-lamp examination findings, including any corneal scarring or thinning
  • A detailed history of all treatments attempted and their outcomes
  • Clinical notes from our eye doctor describing your functional limitations

Beyond test results, the SSA considers how keratoconus affects your ability to perform work-related tasks. A detailed statement from our optometrist describing your visual limitations, such as difficulty with depth perception, reading small print, working at a computer, or navigating unfamiliar environments, strengthens your claim. Keeping a personal log of how your vision impacts daily activities can also provide helpful supporting evidence.

You can apply for Social Security Disability Insurance (SSDI) or Supplemental Security Income (SSI) online, by phone, or in person at a local SSA office. Initial claims are often denied, so many applicants benefit from working with a disability attorney or advocate who understands visual impairment cases. The appeals process includes reconsideration, a hearing before an administrative law judge, and further appellate review if needed.

Treatment Options That Can Preserve Your Vision

When standard glasses or soft contacts no longer provide clear vision, rigid gas permeable lenses, hybrid lenses, or scleral lenses can compensate for the cornea's irregular shape. Scleral lenses vault over the entire corneal surface and rest on the white part of the eye, creating a smooth optical surface that can dramatically improve visual clarity. Our contact lens specialist works closely with each patient to find the lens design that provides the best comfort and sharpness. For those whose keratoconus produces significant astigmatism, toric contact lens designs may also be considered.

Corneal collagen cross-linking (CXL) is the only treatment proven to halt the progression of keratoconus. During this procedure, riboflavin (vitamin B2) drops are applied to the cornea and activated with ultraviolet light. This creates new bonds between the corneal collagen fibers, strengthening the tissue and preventing further thinning. Cross-linking is most effective when performed early, before significant vision loss or scarring has occurred. For a detailed look at treatment approaches and associated costs, visit our page on keratoconus surgery costs and treatment options.

Intracorneal ring segments are small plastic inserts placed within the corneal tissue to reshape its curvature. By flattening the cone and reducing irregular astigmatism, these implants can improve both unaided and corrected visual acuity. They are often considered for patients with moderate keratoconus who struggle with contact lens tolerance. The procedure is reversible, meaning the rings can be removed or exchanged if needed.

In advanced cases where the cornea has become severely scarred or thinned beyond what lenses and cross-linking can address, a corneal transplant may be recommended. Modern techniques such as deep anterior lamellar keratoplasty (DALK) replace only the affected layers of the cornea, preserving the healthy inner layer and reducing the risk of graft rejection. A full-thickness transplant, called penetrating keratoplasty (PKP), is reserved for the most severe cases. Both procedures can restore meaningful vision in patients who might otherwise face disability-level impairment. Our eye doctor can help you understand which approach is appropriate for your situation.

When to See Our Eye Doctor About Keratoconus

When to See Our Eye Doctor About Keratoconus

If you notice increasing blur that your current glasses or contacts cannot correct, frequent prescription changes, worsening glare or halos, or ghost images that interfere with reading and driving, it is time to see our optometrist for a comprehensive evaluation. Early detection and treatment give you the best chance of preserving functional vision and avoiding the level of impairment that could lead to a disability determination.

Our eye doctor will perform corneal topography to map the shape of your cornea, measure your corneal thickness, and assess your best-corrected visual acuity. These measurements help determine the stage of your keratoconus and guide treatment decisions. If you are pursuing a disability claim, this visit also provides the detailed documentation the SSA requires. Understanding the numbers on your lens prescription can be helpful as well, and you can review our guide on understanding your contact lens prescription for more information.

Keratoconus requires regular follow-up to track whether the condition is stable or progressing. Our eye doctor will monitor changes in corneal shape and visual acuity over time, adjusting your treatment plan as needed. Consistent care helps ensure that any progression is caught early, giving you access to interventions like cross-linking before significant vision loss occurs. Keratoconus also falls under the broader category of refractive disorders, and understanding that context can help you make informed decisions about your long-term eye health.

Frequently Asked Questions

Keratoconus alone is not an automatic qualifier. The SSA evaluates the severity of your vision loss rather than the diagnosis itself. If your best-corrected vision in the better eye is 20/200 or worse, you may meet the listing for visual impairment. Otherwise, you would need to demonstrate through medical and vocational evidence that your visual limitations prevent all types of work.

Yes, because the SSA considers your best-corrected vision, successful treatment with scleral lenses, cross-linking, or transplant surgery could improve your acuity above the disability threshold. The SSA may require updated eye exams during the review process. Improvements in corrected vision are a positive outcome, even though they may change your eligibility for benefits.

The SSA primarily relies on a Snellen visual acuity test performed with your best correction in place. Visual field testing may also be required if peripheral vision loss is a concern. Corneal topography, pachymetry (which measures corneal thickness), and optical coherence tomography provide supporting diagnostic evidence but are not the sole basis for a disability determination.

Driving ability depends on the severity of your condition and whether specialty lenses can bring your vision to the level required by your state's Department of Motor Vehicles. Most states require corrected visual acuity of at least 20/40 in one eye for an unrestricted license. Many keratoconus patients can continue driving safely with properly fitted scleral or rigid gas permeable lenses. If night vision is significantly impaired, a restricted license limiting you to daytime driving may be issued.

Yes, keratoconus is a contraindication for LASIK and similar laser refractive procedures because these surgeries remove corneal tissue, which can worsen an already-thinning cornea. Pre-operative screening with corneal topography is specifically designed to identify keratoconus or early signs of corneal weakness before any refractive procedure is performed.
