Abstract: A hand tool that is self-adjusting by alternately squeezing and relaxing the hand grip on the two handles, and that has substantially parallel jaws during closing adjustment. In one embodiment, the jaws have opposing gripping surfaces. In another embodiment, the jaws have opposing cutting blades. All of the operations, except the resetting of the adjustable jaw to a wide open position, can be accomplished with just one hand holding the tool.

Abstract: A hand tool that is self-adjusting by alternately squeezing and relaxing the hand grip on the two handles; that has substantially parallel jaws during closing adjustment; that actually grips the work object with at least an 8-to-1 compound gripping leverage; and that can be locked onto an object when desired with a selectively light or strong grip. All of the operations, except the resetting the adjustable jaw to a wide open position, can be done with just the hand holding the tool and it can be made in the form of an adjustable plier, an adjustable wrench, or an adjustable pipe wrench, plus many other applications.

Abstract: An improved method for making a monolithic intraocular lens and haptic structure. The invention comprises the process of assembling easily available materials into a composite structure having an inner core of optically transparent lens material with broad or selectively tailored wavelength transmission characteristics surrounded by a jacket of colored haptic material having the same composition and mechanical properties as the lens material. The composite structure is then bonded into a monolithic rod with a bonding process wherein the bonding material in the interface between the lens core and the jacket also has the composition and mechanical properties of the lens material. After bonding, the composite structure is sliced into blanks from which lenses with colored haptics can be fabricated.

Abstract: An improved method and assembly for attaching haptics to intraocular lenses. Method and assembly rely on shaping the attachment ends of plastic or metal haptics so that when inserted into openings in the lens, the haptics are firmly secured to the lens by constraining mechanical forces which arise from an added element, by molding or forming the constraint in situ using an external energy source to melt material of the haptic, or by bending a metal haptic to a holding shape. Melting of lens material is not required for this fastening method or assembly nor is wetting of haptic surfaces by material of the lens necessary.

Abstract: A clear, cylindrical, flexible gasket having an annular shoulder located on the interior surface thereof, midway between the ends. The gasket is sized to accept two lens half molds, one on either side of said shoulder to form a lens casting cavity. Each side of the shoulder has first and second annular protrusions extending therefrom for contacting and providing an annular double seal along the edges of each of the half molds. The surface of the shoulder which forms the side of the lens casting cavity is curved in order to reduce stress to a minimum during the shrinkage of the lens casting resin during the cure period. In addition, the casting surface of the shoulder is formed such that the final molded lens will have an outer ridge thereon. One end of the cylindrical gasket has an enlarged edge for additional strength and is provided with index markings thereon which extend beyond the edge and down the outer side of the clear gasket. Two identical fill ports are provided on opposite sides of the gasket.
