Abstract
An ophthalmic surgical instrument for delaminating a retinal membrane includes a handpiece and an actuator mounted on the handpiece. An outer tube has a proximal end mounted to the handpiece. A grasping structure is extendable outwardly relative to a distal end of the outer tube responsive to movement of the actuator. The grasping structure includes a cavity having an opening facing the retinal membrane in use. A blade extends along a portion of the opening and a cushion defining a plurality of openings is positioned within the cavity. Vacuum pressure is applied to a channel in the cushion and coupled to the openings in order to grasp the retinal membrane, which may then be peeled from the retina.
