Abstract: Multi-purpose solutions for contact lens care provide substantial lens wearer/user comfort and/or acceptability. Such solutions include an aqueous liquid medium; an antimicrobial component, preferably a biguanide polymer present in an amount of less than about 5 ppm; propylene glycol or glycerin in an amount sufficient to increase antimicrobial activity; a surfactant component, preferably a poly(oxyethylene)-poly(oxypropylene) block copolymer surfactant, in an effective amount; a phosphate buffer component in an effective amount; a viscosity inducing component, preferably selected from cellulosic derivatives, in an effective amount; and a tonicity component in an effective amount. Such solutions have substantial performance, comfort and acceptability benefits, which, ultimately, lead to ocular health advantages and avoidance of problems caused by contact lens wear.

Abstract: An intraocular lens implantable in an eye includes an optic for placement in the capsular bag of the eye and for directing light toward the retina of the eye. The optic has a central optical axis, an anterior face, an opposing posterior face and a peripheral edge between the faces. The peripheral edge has one or more curved or angled surfaces that reduce glare within the IOL. For instance, a rounded transition surface on the anterior side of the peripheral edge diffuses the intensity of reflected light, or a particular arrangement of straight edge surfaces refracts the light so as not to reflect, or does not reflect at all. The intersection of the peripheral edge and at least one of the anterior face and the posterior face, preferably both of such faces, forms a peripheral corner located at a discontinuity between the peripheral edge and the intersecting face or faces.

Abstract: Solutions useful to clean contact lenses include a surfactant component in an effective amount; and a viscosity inducing component, preferably selected from cellulosic derivatives and more preferably hydroxypropylmethyl cellulose, in an effective amount. Such solutions, which may include one or more additional components, have substantial contact lens cleaning benefits which, ultimately, lead to ocular health advantages and avoidance of problems caused by contact lens wear.

Abstract: A tubing management manifold for a surgical instrument console for controlling fluidflow to and from a surgical instrument includes a housing having a front and opposing sides, and sides, for enabling tubing to be disposed therein and across the housing between the opposing sides. Ports, disposed in the housing front are provided for enabling access to the tubing, disposed across the housing, in order to control fluid flow through the tubing. A tubing capture is disposed on one of the opposing sides, aligned with one of said openings and extending outwardly from said housing, for grasping the tubing in order to prevent unwanted dislodgement of the tubing from said housing.

Abstract: A method and apparatus provided for controlling fluid control to and from an eye or a phacoemulsification handpiece. The handpiece includes an ultrasonically driven, hollow, sleeved needle and the method includes inserting the needle and sleeve into an eye for phacoemulsification of eye tissue and introducing fluid into the eye through an annulus established between the sleeve and the needle. Aspiration of fragmented tissue and fluid from the eye is conducted through the hollow needle. An initial irrigation fluid pressure is determined and the irrigation fluid flow and aspiration fluid flow are adjusted based upon the initial determination. Thereafter continued determination of irrigation fluid pressure is utilized to continuously adjust irrigation fluid flow and/or aspiration fluid flow.

Abstract: A multifocal ophthalmic lens, having outer annular zones with vision correction powers less than a far vision correction power of the patient, is disclosed. These additional annular zones come into play, when the pupil size increases under dim lighting conditions, to thereby compensate for the near-vision powered annular zones. The net effect of the additional near vision annular zones and the additional annular zones having power less than the far vision correction power is to shift the best quality image from in front of the retina to an area on the retina of the eye, to thereby reduce halo effects and improve image contrast.

Abstract: An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens has a first baseline diopter power for distance vision correction and the second ophthalmic lens has a second baseline diopter power for other than distance vision correction. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient or has natural lenses or following removal of the natural lenses.

Abstract: Ophthalmic lenses, for example, intraocular lenses, contact lenses, corneal implant lenses and the like, have multifocal characteristics which provide beneficial reductions in at least the perception of one or more night time visual symptoms such as “halos”, and “glare or flare”.

Abstract: A method of making an intraocular lens having an optic portion joined to a haptic portion by a flexible element which comprises the steps of: (e) forming a core of a material suitable for use as said optic portion; (f) reacting said core to provide a first composite of said optic portion and said flexible element bonded thereto; (g) reacting said flexible element with a material suitable for use as said haptic portion to provide a second composite; and (h) machining said second composite to form said intraocular lens.

Abstract: An intraocular lens for implantation in an eye of a patient includes a multifocal optic and a movement assembly. The optic has maximum add power which is less than the add power required for full near vision for a pseudophakic eye. The movement assembly is coupled to the optic and is adapted to cooperate with the eye of the patient to effect accommodating movement of the optic in the eye. Lens systems including two optics and two movement assemblies are also provided. The intraocular lenses and lens systems are particularly useful when implanted in the eyes of a patient after removal of the natural lenses.

Abstract: An intraocular lens (IOL) insertion apparatus including a cartridge with an IOL-receiving chamber, a handpiece into which the cartridge is loaded, and a plunger rod that extends through a lumen in the cartridge to reliably engage the IOL therein. The chamber is stepped in one section to cause the IOL positioned therein to assume a complex curve. A lip or projection on the plunger rod is aligned with the complex curve and intersects the IOL to reliably engage the IOL across its thickness. The cartridge may be a folding type with a pair of arcuate walls and extension wings joined at a living hinge. The stepped section of the chamber may coincide with the location of the hinge.

Abstract: An intraocular lens includes an optic for focusing light and a movement assembly coupled to the optic. The movement assembly is adapted to cooperate with the eye to effect accommodating movement of the optic. The movement assembly includes a plurality of movement members each with a proximal region coupled to the optic and an enlarged distal region. The enlarged distal region may be integral with the proximal region, or may be mechanically coupled thereto.

Abstract: An ophthalmic lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first ophthalmic lens is biased for distance vision and the second ophthalmic lens is biased for intermediate vision. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient without removal of the natural lens.

Abstract: An intraocular lens (IOL) insertion system, cartridge and/or combination cartridge and folding member that facilitates multiply folding an IOL within a load chamber of the cartridge prior to insertion in an eye. In the system embodiment, a folding member is provided in a handpiece that interacts with the cartridge to multiply fold the IOL therewithin. Alternatively, the cartridge may incorporate the folding member in its structure, or a separate folding member that interacts with the cartridge may be provided in a combination. The folding member may be a planar element that extends through a slot in the wall of the load chamber to displace a midportion of the IOL away from the inner wall of the load chamber. Desirably, the multiply folded configuration that results is an M-shape or a W-shape, depending on orientation. The cartridge may further include structure that retains the multiply folded configuration of the IOL as it passes through an injection tube and into the eye.

Abstract: Intraocular lens combinations are provided which include an axially movable primary intraocular lens (IOL) and a substantially fixed compensating IOL. In certain embodiments, the compensating IOL has no corrective power and serves only to inhibit or reduce the risk of posterior capsular opacification (PCO). In other embodiments, the primary IOL has higher corrective power than required by the patient's prescription in order to amplify the accommodation obtained from axial movement, and the compensating IOL has negative corrective power to compensate for the excessive diopter value of the primary IOL. In a preferred method, the primary IOL is implanted in the capsular bag of an eye, and centered about the optical axis. The compensating IOL is then implanted in the capsular bag, sulcus, or anterior chamber and axially aligned with the primary IOL.

Abstract: An binocular lens system for improving the vision of a patient including first and second ophthalmic lenses. Each of these lenses is adapted for implantation in an eye or to be disposed on or in the cornea. The first lens is biased for distance vision and the second ophthalmic lens is biased for near vision. The ophthalmic lenses may be intraocular lenses which are implanted in the eyes of a patient following removal of the natural lens.

Abstract: An improved ophthalmic lens is disclosed which has a plurality of alternating power zones with a continuously varying power within each zone, as well as in transition from one zone to another. In other words, a plurality of concentric zones (at least two) are provided in which the variation from far to near vision correction is continuous, i.e., from near correction focal power to far correction focal power, then back to near, and again back to far, or vice versa. This change is continuous (progressive), without any abrupt correction changes, or “edges”. Two versions of the invention are disclosed. In the first version continuous, alternating power variation is accomplished by a continuously changing curvature of the lens posterior surface, thereby altering the angle of impact of light rays on the eye.

Abstract: An intraocular lens configured to be implanted in the cornea from the posterior aspect. The lens has an optic and a pair fixation members extending outward therefrom. One of the fixation members includes a single enlarged foot, while the other fixation member has two bifurcated feet. The fixation members are sized and shaped to fix within tunnels formed in the cornea. A method of the invention includes forming tunnels in the stroma layer of the cornea, and positioning the fixation members in the tunnels. The tunnels may be formed from outside or inside the cornea. The method may include inserting the folded intraocular lens into the anterior chamber, permitting the lens to unfold, inserting the fixation member with the enlarged foot in one of the tunnels, and bending the two bifurcated feet of the other fixation member together so as to fit within the other tunnel.
