A method and channeled tool adapted for guiding an intraocular lens into position through an incision in an eye. Indicia means are provided in the tool in the form of two through-holes positioned at pre-determined distances from the distal end of the tool to determine the operable compression range of the intraocular lens haptics so that the surgeon can determine that the subject eye is of a sufficient size to receive the selected intraocular lens.

Method and tool for inserting an intraocular lens

A retainer for retaining an intraocular lens in a sterile liquid in a vial includes an elongated pair of side walls defining a lens-receiving area therebetween. A transversely-extending wall between the side walls defines a support surface for the edges of the haptic of the lens. Ribs on the interior surfaces of the side walls terminate short of the transversely-extending wall to define slots for retaining the haptic of the lens. An access opening is defined by the transversely-extending wall to permit the retained lens to be freed for removal by an instrument from without the confines of the retainer. The retainer terminates in its upper portion in a pair of protruding tabs defining slots for receiving an instrument for removing the retainer and the lens from the vial. The method of inserting and removing the lens from the retainer is also described.

Method and apparatus for packaging an intraocular lens

A surgical scalpel for use in ophthalmic and other forms of surgery having a blade that can be adjustably extended beyond a foot. The scalpel also includes an indicator for showing the length of the blade that is exposed beyond the foot. The indicator can be calibrated to compensate for variations in blade length and other manufacturing tolerances.

Surgical scalpel

An intraocular lens four point contact haptics with an asymmetrical cross section. The ends of each of the haptics are contiguously juxtaposed and inserted in a common bore in the periphery of the optic. The legs of each of the haptics spiral outwardly in juxtaposed relationship, separate and extend away from each other to form eye contacting heel and toe portions residing on opposing sides of the inferior-superior axis of the lens. When two such haptics are employed, a wide haptic compression range can be achieved with little differential in compression force.

Haptic for intraocular lens

An intraocular lens for placement in the anterior or posterior chamber of the eye after extracapsular surgery has one or more haptics having an asymmetrical cross section. The haptic is formed in a continuous loop. Preferably both ends of the haptic are joined to the optic at a single location. A preferred cross-sectional shape is a major segment of a circle.

A lens case for an intraocular lens includes a base carrying a receptacle for a lens holder and a soaking tray. The lens holder is positioned in the receptacle for sliding movement between a first position wherein the lens is securely and protectively held in the lens holder and a second position wherein the lens is released from the lens holder ready for removal from the ca
