Patent number: 6142996Abstract: A device and system for creating small (e.g., less than 3 mm and preferably about 1 mm in cross dimension) openings in the anterior lens capsule of a mammalian eye to facilitate insertion of lens reduction/removal device(s) and/or cannulae for injecting flowable lens replacement materials into the lens capsule. The device generally comprises a handpiece having an electrosurgical probe extending forwardly therefrom. The electrosurgical probe incorporates an annular tip electrode which is positionable in contact with the lens capsule, to create the desired less than 3 mm opening therein. The annular electrode tip may be either monopolar or bipolar in design.Type: GrantFiled: July 9, 1999Date of Patent: November 7, 2000Assignee: Optex Ophthalmologics, Inc.Inventors: Soheila Mirhashemi, Michael Mittelstein, John T.

Patent number: 6117149Abstract: A system and method for reducing and removing and ophthalmic lens of a mammalian eye. The system includes a rotary lens-reducing probe device of either straight or curved configuration, the probe device comprising a tubular outer sheath through which a rotatable drive shaft extends. A rotating lens-reducing head member is positioned on the distal end of the drive shaft. The head member is configured and constructed to draw a flow of fluid and lens matter into contact therewith, thereby facilitating complete reduction of the entire lens without requiring significant axial (i.e., longitudinal) movement of the probe within the lens capsule. The distal portion of the tubular sheath is preferably configured to shield a portion of the lens-reducing head, during operation, to avoid inadvertent damage to lens capsule. Also, the distal portion of the sheath may be aimed or positioned to direct the flow of fluid and lens matter created by the rotating head in a preferred flow path within the lens capsule.Type: GrantFiled: February 11, 1999Date of Patent: September 12, 2000Assignee: Optex Ophthalmologics, Inc.Inventors: John T. Sorensen, Michael Mittelstein, Soheila Mirhashemi
