ABSTRACT:
A method and apparatus for adjusting corneal curvature of the eye comprising an adjustable split ring formed of an elastic hollow shell which is implantable into the cornea in encircling relation to the central optic zone of the cornea. The ring is filled by a predetermined amount with a select quantity of biocompatible material, either a fluid or strands of biocompatible suture material or polymethylmathacrylate, of predetermined size and length.
The biocompatible filler material is strategically located within the elastic shell to alter its dimensions in thickness or diameter and thereby adjust the corneal curvature to correct for refractive error. Further adjustment of the ring may be made post-operatively after implantation by select removal of the biocompatible filler material.
