Grasping structure for membrane removal

Abstract

An ophthalmic surgical instrument for peeling a retinal membrane includes a handle and an actuator mounted on the handle. An outer tube is mounted to the handle and an inner rod extends within the outer tube. A grasping structure is secured to a distal end of the inner rod having first and second polymer arms secured to the inner rod. Each of the first polymer arm and the second polymer arms has a distal end that is angled to conform to the retinal membrane. The actuator is configured to control relative position of the inner rod and the outer tube in order to extend the grasping structure out of the outer tube and withdraw the grasping structure within the outer tube.
