Abstract: An intraocular lens is treated to form a modified passivated outer surface for reducing or eliminating biological reactions of inflammatory origin when the lens is implanted into an eye. The lens is formed from a conventional lens implant material, such as polymethyl methacrylate (PMMA), which is treated as required to create an outer surface region including a relatively high density of hydroxyl groups. This outer surface region is reacted with a selected fluorocarbon carried in a solution with a primer including bonding agents for bonding the fluorocarbon with respect to the hydroxyl groups, thereby creating a thin, substantially inert or passivated outer surface resistant to irritative reaction with tissue or cells when the lens is implanted into the eye.

Abstract: A corrective lens for the in-tact natural lens of the eye which utilizes an optical body formed of a material which is compatable with the tissue of the eye. The optical body is positioned against the natural lens of the eye and is held in place immediately adjacent the natural lens of the eye.

Abstract: An intraocular lens utilizing an optical portion and having at least one appendage with a first end portion connected to the optical portion. A second end portion of the appendage is intended for contacting the periphery of the eye. The terminus of the second end portion of the appendage includes a spacer which is positioned between the terminus of the appendage and the iris. An intermediate portion of the appendage connects the first and second end portions of the appendage.

Abstract: An intraocular lens which is vaulted from contact with the iris utilizing an optical portion having an optical plane. The optical lens is positioned in the eye by connecting a first relatively rigid member to the optical portion. A first member attached to the optical portion and oriented away from the optical plane second part is connected to the first part and orients toward the optical plane in relation to the first part. A second relatively flexible member connects to the second part of the first member to form an appendage unit.

Abstract: An intraocular lens utilizing an optical portion and having at least one appendage connected to the same at the first end portion. The appendage includes a second end portion which is intended for contacting the anatomy of the eye. The appendage also includes an intermediate portion between the first and second end portions which is provided with a substantially closed loop to aid in manipulation of the appendage.

Abstract: An intraocular lens apparatus having an optical lens portion and a mechanism for confining the lens portion within the eye. A marking is applied to the surface of the optical lens portion for indication of a specific zone of the optical lens portion. The marking may consist of an amount of material which is substantially nonreactive to human tissue. The physician is able to align the marking in relation to the pupil of the eye before fixing the optical lens portion within the eye.

Abstract: An intraocular lens having an optical portion with at least one appendage associated with the same. The appendage includes a first portion and a connected second portion. The first portion of the appendage rotates in relation to the optical portion upon the application of an actuating force on the second portion of the appendage.
