Abstract: A bi-focal contact lens having a first lens portion for distance viewing, a second lens portion for near viewing and capable of being shifted, on the eyeball, between a first position in which the first lens portion is seated and centered on the cornea and a second position in which the second lens portion is seated and centered on the cornea.

Abstract: An intraocular lens having a hydrophilic optical element. The hydrophilic material of the optical element is capable of being hydrated by the natural fluid in the eye to expand after implantation to provide an optically correct lens of suitable diameter, to permit implantation of the lens through an incision of minimal length corresponding to the diameter of the dry lens and thus restoring the vision of the patient with minimal trauma. The lens includes position-fixation members and connecting means for securing the hydrophilic optic to the position-fixation member. The position-fixation members are connected to the hydrophilic optic element in such manner that the lens can be seated in the eye prior to expansion of the hydrophilic optic and expansion after seating does not impact substantial movement to the position-fixation members. The invention also includes the improved method of implantation through an incision of minimal length.

Abstract: An intraocular lens having an optic with a positioning hole therein in the form of a through-bore adapted to selectively receive therein either the working tip of a surgical instrument used to manipulate the lens for seating in the eye or a plug for closing the bore. The plug is colored, frosted, or otherwise formed to be at least partially opaque to the passage of light therethrough to thereby substantially reduce the glare-effect which would otherwise be perceived by the user. Means are provided for releasably retaining the plug in the bore.The method of inhibiting the passage of light rays through a positioning hole in an intraocular lens, after the lens is seated in the eye, to substantially reduce the glare-effect.

Abstract: An intraocular lens suitable for use in the posterior chamber of a human eye with position-fixation legs suitable for individually making contact with the ciliary sulcus of the eye at two spaced points thereof. The legs preferably are of polymethylmethacrylate with portions extending counterclockwise and clockwise with respect to the optic to provide sufficient resilience of the free end portion of each leg with respect to the optic to prevent damage to the ciliary sulcus.

Abstract: An intraocular lens which may be inserted into the eye through a smaller incision in the cornea than another lens with an optic of the same diameter and is adapted to seat adjacent the periphery of the iris. The optic is deformable so that the optic may be in contracted condition while the lens is being inserted through the incision.

Abstract: A posterior chamber lens implant for use after extra-capsular surgery, i.e. surgery in which the rear membrane of the lens or posterior capsule is left intact. The lens implant comprises an optic having a front surface and a rear surface and the implant is secured within the posterior chamber of the eye. In one form of the invention, a pair of position-fixation means are adapted to support the optic in the posterior capsule of the eye with the planar rear face of the optic inclined with respect to the posterior capsule, with the superior rear edge of the optic in contact with the posterior capsule and the inferior rear edge spaced from the posterior capsule. While in a second form of the invention, the position-fixation means are such that they press the superior peripheral rear edge of the optic against the posterior capsule for deforming the latter in a manner to space the posterior capsule away from the mid-portion of the rear face of the optic.

Abstract: A posterior chamber intraocular lens having, according to one preferred form, at least one projection extending rearwardly from a location radially outwardly of a peripheral rear edge portion of the optic for spacing, from the mid-portion of the rear surface of the optic, the adjacent region of the posterior capsule containing the tension line. If desired, after implantation of the lens, the posterior capsule may be safely perforated with a laser beam transversely to a line of tension formed by the projection, causing the posterior capsule to tear and form an opening to eliminate any cloudiness of the posterior capsule from behind the optic. According to another preferred form, the lens has a pair of rearward projections, each located radially outwardly of opposite peripheral portions of the optica and cooperating to produce a similar tension and spacing effect.

Abstract: An intraocular lens which may be inserted into the eye through a smaller incision in the cornea than another lens with an optic of the same diameter and is adapted to seat adjacent the periphery of the iris. The optic is deformable so that the optic may be in contracted condition while the lens is being inserted through the incision.

Abstract: An intraocular lens having an optic of sufficiently small dimension so as to permit its insertion through an incision substantially smaller than 5 mm in length. The lens includes a masking means which is deformable between an expanded condition in which it masks the edge portion of the optic which would otherwise cause a glare effect and a contracted condition in which the masking means is located within the confines of said small dimension of the optic.

Abstract: An intraocular lens which may be inserted into the eye through an incision in the cornea which is substantially less than 5 mm in length. The lens includes a lens body which comprises a plurality of lens body portions and magnet means for assembly of the lens body portions within the eye after they are individually inserted through the incision.

Abstract: An intraocular lens having an optic which has a dimension, determinative of the smallest incision through which it can be inserted, of substantially less than 5 mm and which includes a mask overlying a peripheral marginal portion of the optic for preventing glare.

Abstract: An intraocular lens suitable for seating in the ciliary sulcus of the posterior chamber of a human eye utilizing flexible legs individually making substantially single contact points with the interior of the eye and individually comprising compression springs.

Abstract: A posterior chamber intraocular lens having position-fixation legs extending from the lens body and having a suture loosely engaging one of the legs and extending through an aperture in the lens body. Prior to insertion of the lens into a human eye, the surgeon tightens the suture to deform said position-fixation leg to a position adjacent the lens body to facilitate passing that position-fixation leg through the pupil and by the iris for seating in the cul-de-sac between the anterior and posterior capsules after the other position-fixation leg is seated in such cul-de-sac.

Abstract: An intraocular lens with a medial light-focusing lens body includes oppositely disposed position fixation members having seating portions that are respectively resiliently retained between opposed groove portions of the eye. Each of the position fixation members is formed of at least two different materials for beneficial cooperation with the respective portions of the eye.

Abstract: A surgical operating room structure having prep room, operating room and post-operative room around a central core and separated by flexible curtains. The core comprises independently movable sections each having an arm supporting an operating table which is rotatable about the core from one room to the next adjacent room through the curtains.

Abstract: A corneal implant and method of making the same utilizes a corneal plug removed from an eye, frozen solid, and centrally bored to, but not through, its Bowman's or its Descemet's membrane. An artificial plug which is optically clear is inserted in the bore of the corneal plug and attached thereto. The corneal plug with the artificial plug therein is thereafter implanted in a corresponding opening in the cornea of the patient's eye providing a transparent window free of fluid leakage.

Abstract: A surgical instrument for cutting a lens of a human eye inside the eye for removal through a small incision in the cornea. The instrument has a flange at its front end and a snare loop extending through the flange for ensaring the lens and cutting the same while the lens is supported by the flange.

Abstract: An intraocular lens and method of positioning the same in an eye in which the lens includes a layer of material which is soluble in the eye for maintaining the position-fixation members of the lens in contracted condition during insertion thereof into the eye.

Abstract: A surgical instrument having a shank and a hook at one end of such shank with a transversely extending tip for seating the lens in the posterior chamber of the eye with the neck of the hook having a first portion adapted to extend along the anterior side of the iris, a central portion adapted to extend through the pupil and a second portion having said tip adapted to extend along the posterior side of the iris with the tip extending substantially to an inner peripheral surface of the posterior chamber of the eye.

Abstract: A new intraocular lens, suitable for use in artificial lens implantations and having a light-focusing lens body and two position fixation means therefor, is disclosed. One position fixation means extends generally radially from a first region of the periphery of the lens body and the other position fixation means comprising a pair of support members extends generally radially from a second region of the periphery of the lens body spaced from the first region. At least one of the support members of said latter position fixation means is resiliently deformable between a normal undeformed condition, in which the entire lens will not pass through an incision in the eye of a given length and a deformed condition, in which the entire lens will pass through such given incision. During insertion of the lens into the eye, sufficient force is applied to the deformable position fixation means to maintain it in the deformed condition thereof.
