ABSTRACT:
A medical device for removing a thin membrane from the inner surface of an eye. The device comprises a rake that includes a handle having a hollow body from which a slide member telescopes. A plurality of tines are provided on a free end of the slide member, wherein each tine includes a tissue engaging feature provided on a free end of each tine. The tines are extended and retracted from an end of the handle, such that, when completely retracted, only the tissue engaging features protrude from the handle or all tissue engaging features can be retracted into the handle. In operation, the rake is manipulated along an upper surface of the membrane until the tissue engaging features engage the membrane. Once the tines engage the membrane, the rake is moved upward and tangentially away relative to an upper surface of the retina until the membrane is removed therefrom.
