Keratoconus is the most common corneal disease in the U.S. The cornea’s middle thins and gradually bulges outward, forming a noticeable cone shape. This bulging changes how the cornea refracts (bends) light and can cause refractive errors such as nearsightedness and astigmatism. It can also cause swelling and scarring of the cornea, harming vision. Keratoconus usually affects both eyes.
Treatments We Offer
Initially, vision problems from keratoconus can be treated with eyeglasses. But if the astigmatism worsens, specially fitted contact lenses might be needed to reduce the distortion and provide better vision. Another treatment, called corneal collagen crosslinking has recently been shown to stop the progression of keratoconus. A corneal transplant might be necessary to treat the keratoconus if the cornea becomes too scarred or will not tolerate a contact lens.
Why Choose Columbia?
Columbia University has been at the forefront of keratoconus research and treatment. We provide various surgical options for those with advanced keratoconus who ultimately need corneal transplantation.
