Can You Get LASIK with Keratoconus?

by Robert Dinga, O.D.

Keratoconus is a progressive eye condition that affects the shape and clarity of your cornea, the clear, dome-shaped front surface of your eye. In this condition, the cornea thins out and bulges into a cone-like shape, leading to distorted vision. For individuals with keratoconus, the question often arises: Can I get LASIK to correct my vision?

Understanding LASIK and Keratoconus

LASIK (Laser-Assisted In Situ Keratomileusis) is a popular refractive surgery that corrects common vision problems like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism by reshaping the cornea. However, LASIK relies on the stability and thickness of the cornea to be effective and safe. Since keratoconus involves thinning and weakening of the cornea, LASIK is generally not recommended for people with this condition.

Why LASIK Is Not Suitable for Keratoconus Patients

The primary concern with performing LASIK on someone with keratoconus is that the procedure could further weaken the already compromised cornea. LASIK involves removing a small amount of corneal tissue to correct vision, which could exacerbate the thinning and potentially lead to severe complications like corneal ectasia, where the cornea bulges more than before, leading to significant vision problems.

Alternatives to LASIK for Keratoconus

If you have keratoconus, don’t worry, there are treatment options to help manage your vision. These include:

Corneal Cross-Linking (CXL):

This is a minimally invasive procedure designed to strengthen the cornea by increasing the collagen bonds within it. CXL can halt the progression of keratoconus, making it an essential treatment for those with early-stage keratoconus.

Contact Lenses:

Specially designed contact lenses can often provide clear vision for people with keratoconus.

Corneal Transplant:

In severe cases of keratoconus where other treatments are not effective, a corneal transplant may be necessary. This involves replacing the damaged cornea with healthy donor tissue.

Key Takeaways

Understanding that LASIK is not typically recommended for keratoconus is essential. However, with advancements in alternative treatments, there are still effective ways to improve your vision. It’s crucial to consult with an eye specialist to determine the best course of treatment for your specific condition. They can evaluate the severity of your keratoconus and recommend appropriate options to improve your vision.
