CORNEAL IMPLANT AND METHOD OF DELIVERING A CORNEAL IMPLANT

摘要

A method of inserting and securing a corneal implant in engaging and fluid-flow limiting relation to the posterior cornea, such as to treat edema. The method includes securing a corneal implant in fluid flow limiting relation to the posterior cornea through an incision in the eye and securing it in place by a variety of steps such as corneal insertion or laser bonding, and preferably by inserting a removable corneal implant including a central region and a plurality of retention member(s) disposed on the periphery thereof into the eye so as to releaseably and removably engage a portion of the eye and thereby retain the corneal implant in abutting and engaging relation with the posterior cornea. The retention members of the corneal implant may also comprise haptic leg(s) extending from the central region.

1. A method of inserting a corneal implant comprising: creating an incision in the eye in proximity to a cornea, inserting a corneal implant which comprises a central region and at least one haptic leg secured to and extending from a periphery of the central region through the incision, positioning the corneal implant in engaging and fluid-flow limiting relation to the posterior cornea; and securing the corneal implant in said engaging and fluid-flow limiting relation to the posterior cornea by engaging portions of the eye in retaining contact with the at least one haptic leg of the corneal implant by positioning a distal end of the at least one haptic leg in contacting relation to the iris and in biasing relation to the central region of the corneal implant against the posterior of the cornea.
