Abstract

A surgical instrument includes a flexible outer grasping member and a flexible inner grasping member for peeling a membrane from the retina of a patient's eye. The surgical instrument includes a handle and at least one actuator. An outer tube has a proximal end mounted to the handle. The outer and inner grasping members extend outwardly from a distal end of the outer tube, or are configured to extend outwardly from the distal end of the outer tube. The at least one actuator may be used to move at least one of the outer grasping member and the inner grasping member relative to the other such that the inner grasping member and the outer grasping member are brought together to grasp the retinal membrane.
