Abstract: An intraocular lens (IOL) for implantation within a capsular bag includes an optic and a plurality of haptics. The optics has an anterior optic face and a posterior optic face joined by a peripheral wall. The peripheral wall includes a straight portion of uniform width extending posteriorly from the anterior optic face to a flare point and a flared optic edge. The flared optic edge extends posteriorly and widens from the flare point and meets the posterior optic face at a sharp optic corner. Each of the haptics is coupled to the optic at the peripheral wall at respective haptic-optic junctions. The flared optic edge surrounds the peripheral wall between the haptic-optic junctions.

Abstract: A posterior chamber phakic lens made from a foldable, highly biocompatible material. The lens has a generally circular optic and integrally formed, closed-loop haptics. The haptics project posteriorly from the optic and have generally scalloped outer edges when viewed in plan view. Such a construction helps to avoid pupillary blockage and allows for improved aqueous flow around the natural lens.

Abstract: A multifocal ophthalmic lens having a dye or dyes that block the transmission of near UV and/or blue light.

Abstract: An intraocular lens for replacing the natural lens of an eye including a pair of flexible loops connected to and projecting from the optic portion on one side of the first axis, adapted for supporting the IOL in the eye. The loops include outer end portions that terminate outwardly from the peripheral edge and on opposite sides of the second axis. A stabilizing member(s) is connected to and projects from the optic portion on the other side of the first axis from where the loops are connected, adapted for stabilizing the IOL in the eye. The flexible loops and stabilizing member(s) is shaped and dimensioned so that when the loops are moved toward the peripheral edge the outer end portions do not extend beyond the stabilizing member(s).

Abstract: 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.

Abstract: 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.

Abstract: A direct air heater using the air to be heated as combustion air includes means for maintaining a constant flow of air across the burner. The heater also includes means for recirculating inside air and means for controlling the flow of inside air, preferably, to maintain a constant pressure in the space being heated.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A lens case for an intraocular lens includes a base carrying a receptacle for a lens holder and a soaking tray.
