  • Patent number: 4655770
    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.

  • Patent number: 4585455
    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.

  • Patent number: 4536895
    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.

  • Patent number: 4490860
    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.
