Description

ABSTRACT:
An apparatus and method to prevent collapse of the anterior chamber of the eye during ophthalmic surgical procedures. The apparatus has an infusion terminal with external threads or detents which snap fit into interlocking engagement with the eye without the use of sutures. One or more pumps are pneumatically and hydraulically connected to the infusion terminal via a series of tubes to selectively inject air, saline solution and other liquids into the anterior chamber of the eye during the surgical procedure. The apparatus can be remotely operated by the surgeon with a foot pedal to minimize the amount of surgical assistance needed during the procedure. The infusion terminal can also be Y-shaped for attachment to separate air and liquid containing tubes or can have an annular abutment flange to limit the extent to which the infusion terminal can enter the eye.
