Abstract: An ophthalmic surgical instrument for fragmenting the lens nucleus of an eye, and method of use thereof. The instrument includes an elongated handle portion, a tubular head portion at the handle portion distal end, at least three prongs with cutting tips, and a holding ring. The prongs are selectively retractable into and deployable from the head portion. The holding ring selectively contracts and expands to adjust the deployment width of the prongs. The instrument is inserted toward the eye lens through a corneal incision, while the head portion is opened to deploy the prongs to slide over and grasp onto the lens nucleus at a posterior position thereof. The instrument is then withdrawn toward the eye lens anterior while the head portion is closed to retract the prongs, such that the prong cutting tips cut along the lens nucleus, so as to fragment the lens nucleus into multiple segments.

Abstract: Aspects of embodiments pertain to a lens capsule shielding device for cataract surgery, the shielding device comprising a handle and at least one shielding element slidably mounted inside the handle. The shielding element is selectively configurable in an deployed configuration and a retracted configuration, wherein the at least one shielding element, in the deployed configuration, is operable to be positionable between lens portions of the patient's eye and posterior lens capsule portion of the eye and configured to function as a shield for preventing damage of the posterior lens capsule portion during the application of energy for fragmenting lens portions and/or for preventing damage from suction forces applied for the removal of lens fragments.

Abstract: Aspects of embodiments relate to a surgical device for assisting a user of the device to cut a circular incision in an anterior lens capsule tissue, the device comprising an arm member having a proximal end and a distal end, wherein the distal end of the arm member is operative to receive a cutting member; and an actuator arrangement comprising an actuating handle operatively coupled with the arm member, such that, responsive to an operating input provided at the actuating handle, the distal end of the arm member traverses a circular path around a first axis of the tissue to cause the cutting member to form a circular incision in the tissue along the circular path.
