limbal relaxing incisions
A surgical procedure, often performed during cataract surgery, which corrects usually mild astigmatism by flattening the curvature of the eye's clear surface (cornea). Limbal relaxing incisions are inserted at the boundary (limbus) separating the cornea from the white of the eye (sclera). By altering this portion of the eye instead of the center, surgeons are able to preserve the surface and optical qualities of the cornea.
