摘要： Systems and kits for replenishing an electrowetting ophthalmic device are described. In an embodiment, the system includes an electrowetting ophthalmic device including a lens material defining a cavity encasing an aqueous electrowetting solution; a replenishing solution having an osmolarity approximately equal to an osmolarity of the aqueous electrowetting solution; and a container shaped to carry the electrowetting ophthalmic device and the replenishing solution and to position the electrowetting ophthalmic device in contact with the replenishing solution when the electrowetting ophthalmic device and the replenishing solution are carried by the container. In an embodiment, the osmolarity of the aqueous electrowetting solution is higher than an osmolarity of a tear fluid of an eye.

摘要： Lens materials and ophthalmic devices including lens materials that are oxygen permeable and resistant to oil absorption are described. In an embodiment, the lens material includes a copolymer composed of repeating units including: a fluorinated acrylate repeating unit; and a silicon-containing repeating unit, wherein a mass:mass ratio of the fluorinated acrylate repeating unit to the silicon-containing repeating unit is greater than or equal to 2:1.
