Abstract
A method and apparatus for adjusting corneal curvature of the eye comprising an adjustable split device formed of a flexible hollow shell which is implantable into the cornea in encircling relation to the central optic zone of the cornea. The implant is filled by a predetermined amount with a select quantity of solid biocompatible material in various forms such as rings or strands and composed of flexible polymeric materials of various shape and length. The biocompatible filler material is strategically located within the flexible shell to alter its dimensions in thickness or diameter and thereby adjust the corneal curvature to correct for refractive error. Further adjustment of the implant may be made post-operatively after implantation by select removal of the biocompatible filler material, shifting of the material, or addition of new material to the device.
