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 it hydrophobicity). The lenses prepared by this process are also described.

Abstract:
A process for making a prosthetic eye device (10) includes the steps of forming an iris substrate (24) and extending a stem (26) away from the iris substrate (24). A scleral shell assembly (34) is molded, the iris substrate (24) being molded together with the scleral shell assembly (34), the stem (26) extending away from the scleral shell assembly (34). An iris member (38) is provided, the iris member (38) generally matching the appearance of the iris of a natural eye, the iris member (38) further including an aperture (42) extending therethrough. The iris member (38) is assembled to the scleral shell assembly (34), the aperture (42) of the iris member (38) engaging the stem (26). A first, generally transparent, plastic layer (44) is applied to the assembled iris member (38) and scleral shell assembly (34), the first plastic layer (44) generally covering the iris member (38).
Abstract:
The present invention is directed to an organic imaging device having organic detectors on a curved surface. The device may be used for imaging applications such as photography, lightweight camera systems, very high- resolution imaging, lightweight "night vision", robotic vision, and others. A concave housing with a deformable lens is provided. The deformable lens allows for a range of fields of view and focal lengths. The invention may be configured to detect a range of electromagnetic radiation. It may then provide input to a computer, display, or other device for processing or display of the detected radiation as an image.

Abstract:
The invention provides a process of manufacture of an article such as an artificial eye (10, 110, 210) scleral shell, contact lens or the like, wherein a portion (16) of the article is provided by producing a photograph of a corresponding portion of a natural eye, and incorporating that photograph in the article so as to constitute that portion of the article. The invention also provides an article manufactured by such a process.
Abstract:
An accommodating intraocular lens device is provided. The accommodating intraocular lens device comprises a base assembly and a power lens. The base assembly comprises a first open end, a second end coupled to a base lens, and a haptic surrounding a central cavity. The haptic may comprise an outer periphery, an inner surface and a height between a first edge and a second edge. The power lens is configured to fit within the central cavity. The power lens may comprise a first side, a second side, a peripheral edge coupling the first and second sides, and a closed cavity configured to house a fluid. The first side of the power lens may be positioned at a predetermined distance from the first edge of the haptic.
Abstract:
A method of manufacturing an artificial eye for fitting as a whole or partial replacement of a patient's original eye. This is done by providing an image of an iris on a substrate (100, 300) comprising at least a frontal region of an artificial eye, providing a support (108, 308) for the substrate, positioning the substrate and support in a mould (122, 322), and encapsulating the substrate within a mould material (136, 336).
