Abstract
Ophthalmic implants, their methods of use and manufacture. The implants may include a transparent optic portion and a peripheral non-optic portion coupled to the optic portion. The transparent optic portion may be made of a transparent optic material adapted to allow visible light to pass therethrough, and the peripheral non-optic portion may be made of a light absorbing material adapted to absorb visible light.
Claims19
A phakic posterior chamber ophthalmic implant sized and configured for implantation in posterior chamber of a patient's eye, comprising:
- a transparent optic portion that is designed to provide a refractive correction, the transparent optic portion including a central hole that is sized and positioned to provide for flow of aqueous humor through the lens, wherein the transparent optic portion is hydrophilic, has a diameter from 1 mm to 7 mm, and has a central thickness from 100 microns to 400 microns;
- and
- an opaque peripheral non-optic portion coupled to the optic portion and extending peripherally therefrom, the peripheral non-optic portion sized and configured to engage a sulcus of an eye,
- the transparent optic portion made of a transparent optic material adapted to allow visible light to pass therethrough, and an entirety of the peripheral non-optic portion made of a light absorbing material adapted to absorb visible light,
- wherein the transparent optic material and the visible light absorbing material have linear swell indices that are within 5% of each other when exposed to one or both of aqueous humor or balanced salt solution (‘BSS’),
- wherein the transparent optic material and the peripheral portion material comprise the same constituent components except that the peripheral non-optic portion material includes one or more light absorbing components,
- wherein the peripheral portion comprises a plate haptic extending all the way from a periphery of the optic portion to a radially outermost surface of the phakic posterior chamber ophthalmic lens, wherein the radially outermost surface of the plate haptic comprises a sulcus-engaging surface.
