Abstract: Ophthalmic devices suitable for implantation into the eye through small incisions or insertion into an existing orifice are disclosed. These devices are made from a composition comprising crystalline or semi-crystalline polymeric materials which have a glass transition temperature (Tg) of from about ?100° C. to about 37° C., and wherein Tg for the material is lower than Tm for the composition. Disclosed devices include intraocular lenses, corneal inlays, drug delivery devices and implants for reducing intraocular pressure in glaucoma patients.

Abstract: The invention relates to a novel phakic intraocular lens. The positioning arms or haptics of the lens are designed to hold the lens in position and proper orientation without engaging structures within the eye.

Abstract: The invention relates to a posterior chamber phakic intraocular lens with improved fluid flow between the anterior and posterior chambers of the eye. The fluid flow is accomplished by means of an opening situated in the center of the optical portion of the intraocular lens.

Abstract: A phakic intraocular lens includes a body having a flat anterior-facing surface and a curved posterior-facing surface that defines the optical power of the lens. The lens allows fluid to flow between the phakic lens and the iris and between the phakic lens and the natural lens. An enlarged outer rim helps maintain the position of the lens. Some embodiments are provided with openings, channels, or both at the circumferential edge of the flat anterior-facing surface or the lens body to help prevent the flat surface of the lens from sealing against the iris.

Abstract: An accommodative intraocular lens is disclosed. The lens provides multiple focuses as the result of a bi-directional shift along the eye's optical axis, and also minimizes or prevents posterior chamber opacification. The lens includes a first component which consists of an optical body and a haptic body, a second component which is structurally adapted to maintain substantial contact with the posterior surface of the capsular bag of the eye (when implanted in the eye), and a transition zone connecting the first and second components. The method of implanting the lens in the eye and the method of making the lens are also disclosed.

Abstract: Ophthalmic devices suitable for implantation into the eye through small incisions are disclosed. These devices are made from a composition comprising crystalline or semi-crystalline polymeric materials which have a glass transition temperature (Tg) of from about −100° C. to about 20° C., a melting point temperature (Tm) of from about 0° C. to about 37° C., and wherein Tg for the material is lower than Tm for the composition. Disclosed devices include intraocular lenses, corneal inlays, ocular drug delivery devices and implants for reducing intraocular pressure in glaucoma patients; intraocular lenses are preferred.

Abstract: A method of preparing phakic intraocular lenses from hydrophobic materials is described. In this process, the lens is tested to determine whether it can float submerged in an aqueous medium. If it cannot (e.g., if it remains on top of the aqueous medium), the lens is surface treated (for example, by vacuum UV or corona discharge processes) to increase its wetting ability (e.g., to reduce its hydrophobicity). The lenses prepared by this process are also described.

Abstract: A method for treating presbyopia using a scleral insert is described. The scleral insert is prepared from either (or both) of two specific classes of polymeric materials having both viscous and elastic properties. The first class of polymeric materials has a glass transition temperature (Tg) at or below human body temperature (37° C.). The second class of polymeric materials has a melting temperature (Tm) at or below human body temperature (37° C.). The implant is stored in a frozen, rigid, elongated state prior to insertion in to the eye. Once it is placed on or within the sclera the insert responds to the increase in temperature, due to the surrounding physiochemical environment whereby it becomes soft and expands to reach its final shape. This implant can be inserted in to the eye through a much smaller incision than is used with conventional scleral implant techniques.

Abstract: A phakic refractive lens which conforms to the structure of the eye, particularly to the ciliary sulcus, is disclosed. This lens minimizes stresses of the lens on the interior structure of the eye and eliminates excessive vaulting of the lens which tends to deform the shape of the eye and/or structures in the eye. The lenses comprise an optical body and at least one haptic body. The haptic body(ies) is made up of a first portion adjacent to the optical body, a second portion which extends outwardly from the first haptic portion, and a transition zone between the first and second haptic portions (for example, a groove or score line in the lens surface) which permits the second haptic portion to conform to the shape of the ciliary sulcus of the eye.
