Any disease that affects your eyesight can be frightening. Keratoconus, usually diagnosed in the late teens or early adult years, can change the shape of the cornea and distort vision, so it's important to find the right specialist to treat it.

At Yale Medicine, a cornea specialist will work closely with an optometrist to provide the best possible approach, whether you have a mild case of keratoconus, or you need medically necessary contact lenses or specialty surgery. “Our patients are in the center of the picture and have access to the best surgical options and the best lens options,” says Erica Leigh Volker, OD (doctor of optometry).
