APPARATUS AND METHODS FOR CONTROLLING AXIAL GROWTH WITH AN OCULAR LENS
20200012123 · 2020-01-09 ·

One embodiment of an ocular lens includes a lens body configured to contact an eye where the lens body has an optic zone shaped to direct central light towards a central focal point of a central region of a retina of the eye. At least one optic feature of the lens body has a characteristic that directs peripheral light off axis into the eye away from the central region of the retina. Another embodiment of an ocular lens has at least one isolated feature of the lens body that has a characteristic of directing peripheral light off axis into the eye away from the central region of the retina. Methods of making contact lenses include forming the features during the manufacturing process.

20240100791 · 2024-03-28 ·

A system and method for automated production of a hybrid lens product comprising a lens insert embedded within a lens body. The system preferably includes a first carrier for holding at least one first mold half, a second carrier for holding at least one lens insert, and a third carrier for holding at least one second mold half. The system preferably also includes an automated movement enabling pick-and-place subassembly for positioning a lens insert within a first mold half, and for engaging a second mold half with a first mold half.

Weekly and monthly disposable water gradient contact lenses

The invention is related to contact lenses that not only comprise the much desired water gradient structural configurations, but also have a minimized uptakes of polycationic antimicrobials and a long-lasting surface hydrophilicity and wettability even after going through a 30-days lens care regime. Because of the water gradient structural configuration and a relatively-thick, extremely-soft and water-rich hydrogel surface layer, a contact lens of the invention can provide superior wearing comfort. Further, a contact lens of the invention is compatible with multipurpose lens care solutions present in the market and can endure the harsh lens care handling conditions (e.g., digital rubbings, accidental inversion of contact lenses, etc.) encountered in a daily lens care regime. As such, they are suitable to be used as weekly- or monthly-disposable water gradient contact lenses.

Electronics embedded in rigid gas permeable contact lenses

An eye-mountable contact lens is provided that includes electronics encapsulated within a rigid, gas-permeable polymeric material. The rigid, gas-permeable polymeric material can be mountable to a corneal surface of an eye or can be disposed on or within a flexible polymeric material that is mountable to the corneal surface of the eye. The rigid, gas-permeable polymeric material can provide structural rigidity and protection to the electronics and/or can allow for long-term dry storage of a chemical sensor of the electronics. The rigid, gas-permeable polymeric materials of the provided eye-mountable devices can be formed by curing a precursor material on or around the electronics and subsequently removing portions of the polymeric material formed by the curing, e.g., to form a rigid, gas-permeable contact lens that at least partially encapsulates the electronics and that has a curved shape that is able to be mounted to a corneal surface of an eye.
