What are the best treatments for Keratoconus?

The primary goal of Keratoconus treatment is to stabilize the cornea and improve visual acuity, ranging from specialized contact lenses for mild cases to surgical interventions like corneal cross-linking or transplants in advanced stages. Because Keratoconus progression is highly variable, treatment must be personalized by an ophthalmologist based on the degree of corneal thinning and irregular astigmatism.

What are the first-line treatments for Keratoconus?

For patients in the early stages of Keratoconus, the first line of defense is typically non-surgical. Refractive errors caused by the thinning and cone-shaped protrusion of the cornea are often managed with rigid gas-permeable (RGP) contact lenses or scleral lenses. These lenses vault over the irregular corneal surface, providing a smooth refractive surface that significantly improves vision compared to standard spectacles. In our DiseaseMaps community, where 724 members are currently sharing their experiences with Keratoconus, many report that finding the right lens fit is a critical step in maintaining daily function.

Which surgical and medical interventions are available?

When Keratoconus shows signs of progression—measured by worsening corneal topography or refraction—stabilization becomes the priority. The following interventions are commonly utilized in clinical practice:

• Corneal Cross-Linking (CXL): This is the only FDA-approved procedure designed to halt the progression of Keratoconus. It involves the application of riboflavin (vitamin B2) drops followed by exposure to ultraviolet A (UVA) light to strengthen the corneal collagen fibers.


• Intrastromal Corneal Ring Segments (ICRS): Small, crescent-shaped plastic devices (such as Intacs) are inserted into the mid-layer of the cornea to flatten the cone and improve the fit of contact lenses.


• Corneal Transplant (Keratoplasty): Reserved for advanced cases where vision cannot be corrected with lenses or where corneal scarring is significant. Options include Penetrating Keratoplasty (PK) or Deep Anterior Lamellar Keratoplasty (DALK).

Are there emerging treatments or clinical trials for Keratoconus?

Medical research is actively exploring less invasive ways to manage Keratoconus. Current clinical trials are investigating refined cross-linking protocols, such as "transepithelial" (epi-on) cross-linking, which aims to reduce recovery time and patient discomfort by not removing the outer layer of the cornea. Additionally, researchers are studying the genetic markers associated with the disease to potentially develop targeted therapies that address the underlying collagen degradation.

Which specialists should be on my care team?

Managing Keratoconus requires a multidisciplinary approach to address both vision and psychological well-being. Your care team should ideally include:

• Cornea Specialist: An ophthalmologist with fellowship training in corneal diseases to monitor progression and perform surgical interventions.


• Optometrist (Contact Lens Specialist): A professional experienced in fitting specialty lenses (scleral, hybrid, or RGP) specifically for irregular corneas.


• Clinical Psychologist: Helpful for navigating the emotional impact of living with a progressive, vision-threatening condition.

Next steps

• Schedule a comprehensive corneal topography exam with a cornea specialist to establish a baseline for your Keratoconus.


• Consult your doctor about the timing of corneal cross-linking if you have documented progression.


• Join the Keratoconus community at DiseaseMaps.org to connect with others and share experiences regarding lens fitting and surgical recovery.


• Maintain regular follow-ups, as early detection of progression is key to preserving long-term vision.
