Fluid lens assembly

A non-round fluid lens assembly includes a non-round rigid lens and a flexible membrane attached to the non-round rigid lens, such that a cavity is formed between the non-round rigid lens and the flexible membrane. A reservoir in fluid communication with the cavity allows a fluid to be transferred into and out of the cavity so as to change the optical power of the fluid lens assembly. In an embodiment, a front surface of the non-round rigid lens is aspheric. Additionally or alternatively, a thickness of the flexible membrane may be contoured so that it changes shape in a spheric manner when fluid is transferred between the cavity and the reservoir.

Contact lenses having a reinforcing scaffold

Ophthalmic lenses for correcting refractive error of an eye are disclosed. Ophthalmic lenses include an inner optic portion having a scaffold between an anterior portion and a posterior portion. The scaffold is characterized by a substantially uniform thickness formed from a material characterized by a modulus that his higher than the modulus of the peripheral portion. Openings within the scaffold are filled with a low modulus material. When applied to an eye, the lenses are configured to provide one or more lenticular volumes between the posterior surface of the lens and the cornea. The disclosure further relates to methods of correcting refractive errors of an eye such as astigmatism or spherical aberration using the ophthalmic lenses.

The invention relates to a method for producing at least one solid layer and comprises at least the steps of: providing a carrier substrate (4) having a sacrificial layer (8) arranged thereon or arranging a sacrificial layer (8) on the provided carrier substrate (4), producing a useful layer (6) by way of chemical or physical gas phase deposition on the sacrificial layer (8) to form a multi-layer arrangement (2), removing the useful layer (6) as a result of a material weakening produced between the useful layer (6) and the carrier substrate (4), said material weakening being brought about by modifications (12) to the sacrificial layer (8) which were produced means of laser beams (10).

Oxygen permeable contact lenses with thick payloads

A contact lens having a cap, core, and base forming three layers to allow for the contact lens to be thick enough to accommodate a payload, while ensuring sufficient oxygenation of the wearer's eye. The cap and base are each a thin layer of gas-permeable material, each shaped to form an air gap between them and the core. The two air gaps are connected by air passages that traverse the core. Oxygen from an outside environment passes through the gas-permeable cap to reach the outer air gap, through the air passages to the inner air gap, and through the gas-permeable base to reach the cornea of the wearer's eye. The cap may be annular in form, having a center hole such that the cap does not extend over the central zone of the core, reducing a thickness of the contact lens.
