Abstract: An insertion instrument provides improved features for insertion of a lens into the eye through a small incision. A tubular member has a lumen and a split nozzle end portion for spreading after insertion. Ridges on the lumen wall prevent rotation of the lens, and stabilizer components extend from a plunger end portion to maintain the lens compressed and to prevent lens rotation in moving through the lumen.

Abstract: An accommodating intraocular lens to be implanted within the natural capsular bag of a human eye from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant. During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis about haptics on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule of the bag in which the posterior capsule is stretched rearwardly.

Abstract: An intraocular lens provides substantially increased depth of focus for accurate near and far vision with an optic much thinner than a natural lens, and the lens being rigid, vaulted posteriorly and adapted for posterior positioning in the capsular bag. The optic is positioned substantially farther from the cornea than a natural lens, so that a cone of light exiting the optic to impinge upon the retina is much smaller than a cone of light from a natural lens. Typically, the optic may be about 1.0 mm thick and its distance from the cornea 7.0-8.0 mm.

Abstract: An accommodating intraocular lens having anteriorly and posteriorly movable extended portions, such as T-shaped haptics, extending from a central optic to be implanted within a natural capsular bag of a human eye with the extended portions positioned between an anterior capsular rim and a posterior capsule of the bag, whereby during a post-operative healing period, fibrosis occurs about the extended portions to fixate the lens in the bag in a manner such that subsequent natural contraction and relaxation of the ciliary muscle moves the optic to provide vision accommodation of increased accommodation amplitude and diopters of accommodation.

Abstract: Collars are disposed on loops of intraocular lenses for improved fixation of loops in rims of capsular bags of eyes. A collar may preferably be positioned on an outer portion of a loop and retained on the loop by an enlarged end portion of the loop.

Abstract: An accommodating intraocular lens having anteriorly and posteriorly movable extended portions, such as T-shaped haptics, extending from a central optic to be implanted within a natural capsular beg of a human eye with the extended portions positioned between an anterior capsular rim and a posterior capsule of the bag, whereby during a post-operative healing period, fibrosis occurs about the extended portions to fixate the lens in the bag in a manner such that subsequent natural contraction and relaxation of the ciliary muscle moves the optic to provide vision accommodation of increased accommodation amplitude and diopters of accommodation.

Abstract: An intraocular lens has a lesser dimension longitudinally of haptics attached thereto than in the longitudinal direction to provide increased posterior vaulting for accommodation.

Abstract: Intraocular lenses for implanting within natural capsular bags of human eyes have features on distal end portions to prevent movement or sliding thereof relative to fibrosis pockets or tunnels defined about proximally adjacent haptic portions to fixate haptics against dislocation.

Abstract: An accommodating intraocular lens to be implanted within the natural capsular bag of a human eye from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant. During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis about haptics on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule of the bag in which the posterior capsule is stretched rearwardly.

Abstract: Improved laser keratotomy is provided by defining a pocket in a cornea and insertion thereinto of a spatula or cutting blade having thereon reflective or opening means for controlling application of a laser beam to corneal tissue in anterior or posterior pocket walls to control and define areas of ablation of corneal tissue.

Abstract: The two sides of a multiple cavity mold having electroformed mold cavities for molding intraocular lenses with integral haptics are made by a preferred electroforming procedure involving the use of either a single primary master having a single cavity corresponding to the portion of the lens at either side of its median plane transverse to its optic axis if the lens to be molded is symetrical about both this transverse median plane and its longitudinal median plane containing the optic axis, or a pair of primary masters having single cavities, respectively, corresponding to the portions of each lens at opposite sides of its transverse median plane if the lens is unsymmetrical about either plane.

Abstract: An accommodating intraocular lens to be implanted within the natural capsular bag of a human eye from which the natural lens matrix has been removed through an anterior capsulotomy in the bag circumferentially surrounded by a capsular remnant. During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis about haptics on the implanted lens, and the lens is deflected rearwardly to a distant vision position against the elastic posterior capsule of the bag in which the posterior capsule is stretched rearwardly. After fibrosis is complete, natural brain-induced contraction and relaxation of the ciliary muscle relaxes and stretches the fused remnant and increases and reduces vitreous pressure in the eye to effect vision accommodation by the fused remnant, the posterior capsule, and vitreous pressure.
