Patent number: 5843188Abstract: A method of providing an artificial lens inserted into the eye between the iris and the natural lens zone, there being eye ciliary muscles located peripherally of the zone, that includes providing the artificial lens to be compliant and to have anterior and posterior surfaces, and haptics extending away from the periphery of the artificial lens; and inserting the artificial lens to extend into position between the iris and the zone, and to cause the haptics to extend into adjacency to the ciliary muscles, and; allowing the haptics to adhere to the ciliary muscles; whereby subsequent movement of the ciliary muscles causes movement of the haptics transmitted to effect bodily movement of the lens in posterior and anterior directions to change the angularity of refraction of light passing through the lens toward the eye retina.Type: GrantFiled: October 20, 1997Date of Patent: December 1, 1998Assignees: Henry H.

Patent number: 5776139Abstract: An apparatus used for intraocular implantation of a plastic lens in an internal eye zone, as via a surgical incision in the corneo-scleral limbus, which includes two elongated lever arms, each of which has a distal first zone for gripping the lens, a second pivot zone rearward of the distal zone, and a third manual pressure receiving zone; the arms coupled together rearwardly of the third zones so that the first distal zones are yieldably urged toward one another by the arms to grip the lens therebetween for intraocular implantation; the second pivot zones configured to pivot in interengagement in response to controllable manual squeezing force exertion on the third zones, thereby to cause the first zones to relatively separate, freeing the lens for release in the internal eye zone.Type: GrantFiled: February 18, 1997Date of Patent: July 7, 1998Assignees: Henry H.
