Cornea endothelial protection method

Claim 1

A method of protecting the corneal endothelium by maintaining the curvature of the cornea at a spaced apart position from an intraocular lens implant and controlling pressure in the anterior chamber of an eye comprising: (a) forming a plurality of small apertures which extend through the cornea and into the anterior chamber of the eye by simultaneously inserting a plurality of cannulated needle members into and through the cornea into contact with the lens implant, each of said cannulated needle members having first and second ends, the first ends of said members spaced apart and arrayed for insertion through the cornea and into the anterior chamber of the eye for contact with the lens implant with the second ends of said needle members being arrayed with respect to each other and communicating with a manifold for allowing introduction of a fluid therein from said manifold, said manifold being configured such that frontal access to the central portion of the cornea and the lens implant is unrestricted; (b) contacting the peripheral regions of the lens implant with said first ends of said needle members in order to prevent movement of the lens implant; (c) introducing a fluid through said manifold and into said cannulated needle members and into said anterior chamber to increase the pressure in said anterior chamber in order to move the corneal endothelium away from the lens implant while said first ends of said needle members maintain the desired position of the lens implant; and (d) maintaining the pressure of said fluid at a predetermined level.

Claim 2

A method of protecting the corneal endothelium by maintaining the curvature of the cornea at a spaced apart position from an intraocular lens implant and controlling pressure in the anterior chamber of an eye comprising: (a) forming a plurality of small apertures which extend through the cornea and into the anterior chamber of the eye by simultaneously inserting a plurality of cannulated needle members into and through the cornea into contact with the lens implant, each of said cannulated needle members having first and second ends, the first ends of said members spaced apart and arrayed for insertion through the cornea and into the anterior chamber of the eye for contact with the lens implant with the second ends of said needle members being arrayed with respect to each other and communicating with a manifold for allowing introduction of a fluid therein from said manifold, said manifold being configured such that frontal access to the central portion of the cornea and the lens implant is unrestricted; (b) contacting the peripheral regions of the lens implant with said first ends of said needle members in order to prevent movement of the lens implant; (c) introducing a fluid through said manifold and into said cannulated needle members and into said anterior chamber to increase the pressure in said anterior chamber in order to move the corneal endothelium away from the lens implant while said first ends of said needle members maintain the desired position of the lens implant; and (d) maintaining the pressure of said fluid at a predetermined level.
