Abstract: Soft hydrophobic acrylic materials with improved resistance to fluid diffusion and suitable mechanical properties that allow deformation upon application of force are disclosed. The acrylic materials are particularly suitable for use in fluid-based accommodating intraocular lenses and comprises combination of a perfluoro-substituted alkyl (meth)acrylate and an alkyl (meth)acrylate, and a cross-linking agent.

Abstract: A method and system provide an ophthalmic lens including a lens body having a chamber therein, a reservoir module coupled with the lens body and an optical fluid. At least part of the lens body is flexible. The reservoir module includes a reservoir and a heat sensitive portion bordering the reservoir. The reservoir has a reservoir volume and is fluidically connected with the chamber. The heat sensitive portion has a shape responsive to a temperature of at least forty five degrees Celsius such that the reservoir volume changes in response to at least part of the heat sensitive portion reaching the temperature. The optical fluid resides in the chamber and the reservoir. A change in the reservoir volume flows a portion of the optical fluid between the reservoir and the chamber such that the flexible portion of the lens body undergoes a shape change corresponding to a base power change.

Abstract: Disclosed are high refractive index, hydrophobic, acrylic materials. These materials have both high refractive index and a high Abbe number. This combination means the materials have a low refractive index dispersion and thus are especially suitable for use as intraocular lens materials. The materials are also suitable for use in other implantable ophthalmic devices, such as keratoprostheses, corneal rings, corneal implants, and corneal inlays.
