摘要:
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.
摘要:
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.

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.

摘要:
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).
摘要:
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.
摘要:
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.
摘要:
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.
摘要:
A device detects a discontinuity in the communication of a sensor with a patient by detecting separation of the sensor from the patient. An alarm responds to the detected separation of the sensor from the patient to signal the discontinuity in the sensor operation. The device is particularly useful with a patient warming device which is responsive to the patient's temperature as sensed by the sensor for controlling the heat applied to the patient.
摘要:
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.
