Abstract: A method of manufacturing an intraocular lens that has been customized to provide optimum vision for an eye with prior corneal refractive surgery. Such a custom manufactured IOL will address not only optical correction requirements as currently met by spherical or toric-shaped IOLs, but will correct higher order optical aberrations using needed optimum customized shapes.

Abstract: A method of locating and marking the intersection of the visual axis and the corneal surface. With the method of the present invention, the patient fixates simultaneously at a fixation target and at a distant target laser beam for achieving coincidence of both. Fluorescein dye is placed on the corneal and fluoresces at the location where the beam intersects the cornea. This intersection point can be marked, for example, with a visible dye.

Abstract: A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and a pair of integrally formed haptics. The haptics project posteriorly from the optic. A plurality of holes or slots are formed along the edge of the optic and along the length of the haptics. A soft, highly biocompatible material may be placed into the holes or slots by a friction fit or a primary/secondary molding process. Such a construction helps to avoid pupillary blockage, allows for improved aqueous flow around the natural lens and provides a spacer to hold the lens away from the anterior capsular and the iris.

Abstract: An environmental chamber that can be fixed to the eye during laser refractive surgery. The chamber is held in place by a suction ring or the like and contains a window that is transparent to necessary ultraviolet radiation, visible light and infrared radiation wavelengths. The chamber is connected to a control system that controls the temperature and humidity within the chamber and provides for the evacuation of ablation by-products from the surgical site.

Abstract: An implant system which facilitates and improves the non-penetrating deep sclerectomy/canalostomy surgery by assured maintenance of the scleral aqueous filled space by a basic permanent chamber which can be easily connected into the opening of the Schlemm's canal by adjustable connecting tubes. This implant system also provides surgical options for penetrating through Descemet's membrane as well as for outflow into the subconjunctival space though the superficial scleral layer.

Abstract: Non-aspirating viscoelastics, compositions and methods of use are disclosed. The non-aspirating, transitional viscoelastics possess sufficient viscosity to be useful in ophthalmic viscosurgery, but may be left in the eye with little or no resulting IOP spike.

Abstract: The application of switchable tackiness coating compositions to ophthalmic implants provides the benefits of body temperature tackiness without the disadvantages of room temperature tackiness.

Abstract: A diffractive optical ICL made from two different hydrogel materials that are biologically acceptable for long term implantation in the cornea. The first material has a higher refractive index than the cornea and it is bound to the second material which has a refractive index similar to corneal tissue. The interface between the two materials consists of a microstructured diffractive surface. The adequate permeability of metabolites through both of the hydrogels of the diffractive ICL yields a safe implant for the cornea. Alternatively, the lens may be made of a single material and/or have an edge geometry that minimizes corneal irritation and allows the lens to sit within the corneal tissue smoothly and relatively flat.

Abstract: Bicomposite intraocular lenses having an anterior surface material different from a posterior surface material are disclosed. The posterior surface material reduces the risk of posterior capsule opacification.

Abstract: Intraocular lens coating compositions for reducing the risk of posterior capsule opacification are disclosed. The coating materials, which differ from the substrate material, consist essentially of at least two aryl acrylic hydrophobic monomers of the formula wherein: X is H or CH3; m is 0-10; Y is nothing, O, S, or NR wherein R is H, CH3, CnH2n+1 (n=1−10) iso OC3H7, C6H5, or CH2C6H5; Ar is any aromatic ring which can be unsubstituted or substituted with CH3, C2H5, n-C3H7, iso-C3H7, OCH3, C6H11, Cl, Br, C6H5, or CH2C6H5.

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 having improved biocompatibility is coated with polyethylene oxide through covalent bonding, preferably using a plasma-deposited amine layer. The lens is then sterilized with ethylene oxide and extracted with water.

Abstract: A supplemental intraocular lens is provided for either preoperative or postoperative attachment to a conventional implanted intraocular lens to provide an adjustable or removable multi-focal optic or to provide a necessary optic of spherical, cylindrical or combination shape for refractive error correction in aphakic patients. An intraocular lens system is also provided including a primary intraocular lens modified to provide for securing a supplemental corrective intraocular lens to the primary lens. Either the primary or supplemental lens could be formed of a suitable multi-focal lens, or both lenses could be mono-focal.

Abstract: A method for attaching a pair of colored haptics (20) to an optic (10) of an intraocular lens (1), containing the steps of providing the peripheral edge (17) of the optic (10) with a pair of holes (12), inserting the end portions (21) of the haptics (20) into the holes (12), aiming a laser emitting radiation within the visible spectrum at the end portion (21) of the haptic within the hole (12) in the optic (10) and firing the laser so that the radiation passes through the optic (10) essentially without absorption and is absorbed by the haptic (20), thereby causing the haptic (20) to fuse with the optic (10).

Abstract: Intraocular lenses with three zones for the provision of bifocal vision are described. Methods for the lenses use are also described.

Abstract: A lens for implantation into the cornea of the eye for providing correction for myopia and myopia with accompanying astigmatism wherein a corneal cap section is removed and an implant bed is created to receive the intracorneal lens. The intracorneal lens is formed of a hydrogel type material or other material highly compatible with corneal physiology. In the range of lens powers of approximately -1.0 diopters to -30.0 diopters, the posterior radius of curvature conforms to the receiving surface of the lamellar bed of the cornea and the anterior surface has the radius of curvature necessary to provide the desired lens power for achieving the desired change in the refractive power of the cornea. The lens includes a peripheral transitional zone to join the anterior surface and posterior surface to allow the lens to be implanted onto the corneal bed and to allow for a smooth overlay of the replaced corneal cap section.

Abstract: A method for attaching a polymethylmethacrylate haptic having a colored core to an optic of an intraocular lens, containing the steps of providing the periphery of the optic with a pair of intersecting holes, inserting an end of the haptic into one hole, inserting an end of a polymethylmethacrylate anchor strand having a colored core into the second hole so that the end of the anchor strand and the end of the haptic intersect, aiming a laser capable of a transmitting energy of a visible wavelength at the intersection of the first and second holes, firing the laser through the optic at the point of intersection of the end of the haptic and the end of the anchor strand, wherein the optic transmits, but essentially does not absorb, the laser energy and the core the anchor strand and the core of the haptic absorb a portion of the laser energy sufficient to fuse the end of the anchor strand and the end of the haptic at their point of intersection.

Abstract: The tool and method for preparing for insertion into an eye an intraocular lens formed of a compressible material includes an elongated hollow chamber with an inlet end and an outlet end. An intraocular lens formed of a compressible material is extruded to a smaller size that fits in the elongated chamber by a compresser which includes an outlet adapted to be aligned with the inlet end of the elongated chamber. The extruded intraocular lens is pushed through the elongated chamber from the inlet end through to the outlet end.
