ADJUSTABLE DEVICES FOR CORNEAL CURVATURE ADJUSTMENT

摘要

The intrastromal corneal ring (ICR) (47) is adjustable in thickness and has an elongated, flexible preferably transparent or translucent body which forms a circle. The thickness may be adjusted prior to insertion into the cornea and may not be further adjustable after insertion. In preferred embodiments, the thickness of the ICR may be adjusted after insertion to more precisely adjust the shape of the cornea (12) and focus the light entering the eye on the retina (18).
