AK/LRI

AK

Astigmatic Keratotomy (AK) is used to help people with astigmatism. Astigmatism is an uneven curvature of the cornea. It is curved more in one direction than the other, causing a distortion in vision. During AK, one or more surgical incisions are made in the cornea. These incisions help eliminate the uneven curvature and "round out" the cornea. A rounder cornea means objects no longer appear blurred or distorted. AK is sometimes performed at the time of cataract surgery, in order to reduce or eliminate the patient's preexisting astigmatism.

LRI

A Limbal Relaxing Incision (LRI) is similar to AK. Limbal Relaxing Incisions are incisions placed in the limbus (edge of the cornea). These incisions relax the limbus to create a more rounded cornea and reduce astigmatism. LRI's may also be performed at the time of cataract surgery.
