A recently filed patent (Publication Number: US20230140249A1) describes an ophthalmic implant designed to improve vision. The implant consists of a transparent optic portion and a peripheral non-optic portion. The transparent optic portion is made of a material that allows visible light to pass through, while the peripheral portion is made of a light-absorbing material that absorbs visible light. The peripheral portion is designed to engage with the sulcus of the eye.

The patent claims specify that the transparent material and the light-absorbing material should have similar linear swell indices when exposed to aqueous humor or balanced salt solution. This ensures compatibility and stability of the implant within the eye. The claims also mention that the transparent optic material and the peripheral portion material may have the same constituent components, except for the presence of visible light-absorbing components in the peripheral portion material.

The peripheral portion of the implant extends from the periphery of the optic portion to the outermost surface of the implant. It includes a transition zone adjacent to the optic portion, which connects to a supporting structure of the peripheral portion. The size of the peripheral portion is determined based on the visual impairment the implant is designed to treat.

The patent claims also cover various shapes and sizes of the implant. The diameter of the optic portion can range from 1 mm to 7 mm, while the width of the lens can range from 10 mm to 14 mm. The central thickness of the implant can vary from 100 microns to 400 microns, with a peripheral region thickness between 50 and 200 microns. The edge thickness of the optic portion is less than 700 microns.

Additionally, the patent claims describe the use of the implant to correct different types of vision impairments, including myopia, hyperopia, astigmatism, and presbyopia. The transparent optic portion can be configured as an extended depth of field optic to treat presbyopia, providing a potential solution for age-related vision loss.

Overall, this patent describes an ophthalmic implant with a unique design that combines a transparent optic portion with a light-absorbing peripheral portion. The implant offers potential benefits for correcting various vision impairments and treating presbyopia.
