Abstract: The blade has a forward pointed end with two forward cutting edges which flare outward and rearward to intermediate cutting edges that are parallel to the centerline which in turn extend rearward to two rear cutting edges which flare outward and rearward to two non-cutting edges. The angle of each the forward cutting edges relative to the centerline is smaller than the angle of each of the rear cutting edges relative to the centerline.

Abstract: The knife has a handle with a blade attached to one end of the handle. The blade has two opposite sides and two edges extending from the handle to a forward cutting edge portion. The two edges are blunt and are non-cutting edges. In one embodiment, the forward cutting edge portion is formed by a pointed inverted V shaped cutting edge extending forward of two outwardly extending straight cutting edges on opposite sides of the base of the pointed inverted V shaped cutting edge with the point of the pointed inverted V shaped cutting edge being located along the centerline of the blade. The outwardly extending cutting edges are transverse to the centerline. In another embodiment, the cutting edge portion is formed by a first edge portion transverse the centerline of the blade and an angled portion located next to one of the non-cutting edges. The angled portion forms an obtuse angle relative to the first edge portion and which extends forward of the first edge portion.

Abstract: The refractive surgery keratotomy knife has a handle with a footplate and a holding member for receiving and holding a flared surgical blade fixed to the handle and knife body. The footplate is adapted to be placed against the cornea of the eye. The blade is held by a blade support with the cutting edge of the blade extending beyond the footplate for forming an incision in the cornea of the eye by pressing the blade directly into the cornea tissue.

Abstract: The marker is a hollow cylindrical member having a given height between two opposite ends and a given radius with an opening extending therethrough between the two ends and a central axis extending through the opening. One of the ends is a cornea engaging end and the other end is a viewing end. Two aligned spaced apart pointing members extend radially inward to the central axis of the opening from one side of the member such that when viewed from either end, from the central axis, the two pointing members are radially aligned. The pointing member closest to the viewing end has a width not greater then the width of the other pointing member. In another embodiment, a solid pointing plate is employed instead of the two pointing members.

Abstract: The refractive surgery keratotomy knife has a handle with a footplate with an opening for receiving a surgical blade. The footplate is adapted to be placed against the cornea of the eye. The blade is held by a blade support member which can locate the cutting edge of the blade in the opening of the footplate and beyond for forming a radial incision in the cornea of the eye by being pressed directly into the cornea tissue. The cutting edge of the blade is fixed at an acute angle relative to the bottom of the footplate either due to the design of the blade or with the use of an adjusting mechanism of the knife.

Abstract: The hydrodissection needle has a sharp tip end and at least two elongated outlet openings which are located at or near the needle tip with their elongated axes extending rearward. In another embodiment, at least one elongated helical outlet opening is provided near the needle tip end.

Abstract: In one implantation process, the intraocular lens implant is placed partially or completely on the anterior capsular surface of the human crystalline lens and is attached thereto by means of glue or adhesive. The implant has overall edge-to-edge dimensions such that it does not extend beyond the periphery of the human lens. In several embodiments, adhesive receiving wells are formed in the implant lens near the periphery to facilitate attachment of the implant lens to the human lens. In another embodiment, the implant lens has structure extending from its posterior side for engaging the human lens to space the implant lens from the human lens. In still another embodiment the posterior side of the implant lens is vaulted such that the central portion of the implant lens does not engage the human lens.In another implantation process, the intraocular lens is attached to a previously implanted intraocular lens for optical correction purposes. Attachment may be with adhesives or mechanical means such as clips.

Abstract: An artificial intraocular lens or optic is attached to the capsular membrane or iris of the eye with adhesive after the human lens is removed or upon removal of a previously implanted artificial intraocular lens. The optic also may be attached to the iris with adhesive with the human lens in place to correct for deficiencies of the eye. The lens implant may have holes or wells for receiving adhesive for attachment purposes.

Abstract: The intraocular implant has a solid, non-inflatable, non-expandable, transparent optic member and an annular inflatable haptic member coupled to and circumferentially surrounding the outer periphery of the optic.

Abstract: The intraocular lens includes a lens body having a haptic for supporting the lens body in a human eye. The haptic includes a surrounding portion adapted to engage the tissue of a human eye and which extends at least 360.degree. around the axis of the lens body at a position spaced outward from the periphery thereof. The haptic comprises a single haptic member in one embodiment and a plurality of haptic members in another embodiment each comprising an inner connecting portion having its inner end joined to the periphery of the lens body and extending outward and then around or partially around the axis of the lens body forming the surrounding portion and having an outer portion with an outer end portion. In the case of a single haptic member the haptic member overlaps itself. In the case of a plurality of haptic members each, each haptic member has an outer portion with its outer end portion which overlaps an adjacent portion of another haptic member.

Abstract: The intraocular lens may have closed loop haptics or open loop haptics. Each closed loop haptic has two coil portions and each open loop haptic has one coil portion. The purpose of the coil portions is to provide the desired flexibility and to provide for geometric stable haptic flexion upon the application of compression force to the peripheral portions of the haptics towards the lens body.

Abstract: An intraocular insert suitable for use as an artificial lens implant in the anterior or posterior chamber of a human eye comprising a circular lens body having two position fixation members extending from opposite sides of the periphery of the lens body. The two fixation members are of similar shape but are asymmetrically arranged relative to the circular lens body. Each of the fixation members comprises an arm portion having a base joined to the periphery of the lens body with said arm portion extending from said lens body, an elbow, and an elongated outward-convex seating portion having a first end joined to said arm portion by said elbow and an opposite free end extending in a direction such that said elongated outward-convex seating portion is outward of said arm portion relative to said lens body. Each arm portion is generally parallel to a line tangent to said lens body. Said arm portions of said two fixation members extend from said lens body in opposite directions relative to each other.
