ABSTRACT:
A sleeve apparatus for use in combination with a surgical instrument for the removal of a cataract through an incision in a patient's eye. The sleeve apparatus includes a first sleeve member having an interior longitudinal bore through which at least a portion of the surgical instrument is insertable. A second sleeve member, substantially concentric to and operatively attached to an outer surface of the first sleeve member, substantially surrounds a portion of the first sleeve member to create a chamber for receipt of expansion material therebetween. The second sleeve member is resilient and expansile in circumference due to the presence of expansion material within the chamber, so as to substantially conform to the shape of the incision and/or the interior of the wound and substantially seal the incision and reduce the loss of fluid from the patient's eye during surgery.
