摘要:
A viscoelastic solution including a buffered solution, 0.01-10% chondroitin sulfate, 0.01-10% hydroxypropyl methylcellulose, and 0.01-10% sodium hyaluronate, pH adjusted to 6.0-8.0 at a osmolarity between 200-400 mOsmol/L. The buffered solution can be HEPES buffered minimal essential medium (MEM), phosphate buffered saline (PBS), or buffered balanced salt solution. A cell growth factor or cell growth supplement can also be included in the solution.
摘要:
A defined serumfree medical solution for applications in Ophthalmology, that contains one or more cell nutrient supplements which maintains and enhances the preservation of eye tissues, including human corneal tissues at low temperatures (2.degree. C. to 15.degree. C.). This solution is composed of a defined aqueous nutrient and electrolyte solution, supplemented with a glycosaminoglycan(s), a deturgescent agent(s), an energy source(s), a buffer system(s), an antioxidant(s), membrane stabilizing components, antibiotic(s), ATP precursors and nutrient cell supplements.
摘要:
An additive for intraocular irrigation solution or surgical solution which provides the anterior chamber and posterior chamber of the eye with protection during surgical procedures that require irrigation. The additive for the solutions is composed of a balanced salt solution containing dextrose supplemented with chondroitin sulfate. Other chemical compositions can supplement the additive.
摘要:
Intraocular lens including loop haptic members each affixed at more than one point to a soft skirt of an optic or to a soft optic for torsional rigidity of the loop haptic member and for preventing loop rotation or pull out in an optic. The loop haptic members each include a main loop haptic member, and two branch members proceeding from the main loop haptic member to affix in securement holes in the edge or surface of an optic. The loops' securement end points include conically shaped end like members which engage within the soft portion of the IOL.
摘要:
Intraocular lens implant including an optic such as a plano-convex lens, a plurality of outwardly extending loops, and at least one key-hole affixed to one of the loops. In one embodiment, a plano-convex posterior chamber lens implant is provided with at least one key-hole loop in one of the two loops for turn-key insertion by locking a turn-key insertion instrument into a key-hole where the key-hole is at one end of one or both of the loops. The key locking into the key-hole provides for turn-key insertion of the loop with stable, secure, fixation, and control of the superior loop providing movement in all directions and all planes. This provides for rotation of the loop to rotate the lens implant posterior to the iris or into the capsular bag during a superior loop insertion technique.

摘要:
Intraocular lens including a lens optic having two haptic loops secured substantially adjacent to each other near a common point of the lens optic, and extending about the lens optic to a position opposing the common point of securement about the lens optic. The haptic loops can include notches and positioning holes and the optics can include positioning holes. The mirror image haptic loops assume geometrical haptic configurations of circular segments substantially conforming equidistantly about the circumference of the lens, a two straight sided configuration with a connecting outwardly curved circular segment, a two straight sided configuration with a connecting inwardly curved circular segment, two circular segments with a connecting inverted circular segment, or three circular segments with two connecting inverted circular segments. The lens optics can be plano-convex, bi-convex, meniscus or other like optic configurations, including reversed optics. The lenses can be lathe cut or injection molded. The haptic loops can also be angled forward or planar. An insertion slide is included for assisting in inserting a lens into the eye.
摘要:
An intraocular lens denoted as a YAG dimpled lens or dimpled YAG lens, which includes a barrier rim and a YAG spacer area in a posterior surface of the lens. The barrier rim is 2-4 mm in longitudinal length and the YAG spacer is 3-4 mm in longitudinal length across the surface diameter of an optic of the intraocular lens. The lens optic can be either plano-convex or bi-convex. A cutout for the dimpled YAG spacer is provided which is either a convave or a substantially rectangular geometrical configuration in the posterior surface of the lens. The YAG spacer can also include a trough or a groove geometrical configuration, such as in the configurations of a Maltese cross, a circular trough or groove, or a circular trough or groove with a Maltese cross therein. The barrier rim is 33% to 80% of the total surface are of the posterior surface of the lens.
