Tuan Anh Nguyen - Orange CA
Assignee:
Visiogen, Inc. - Irvine CA
International Classification:
B29D 1100
US Classification:
264 25, 425808, 623901
Abstract:
There is disclosed a method of making an intraocular lens having first and second viewing elements. The viewing elements are interconnected by a plurality of translation members extending from a periphery of the first viewing element. At least one of the translation members comprises a plurality of arms, and at least one of the viewing elements includes an optic having refractive power. The method comprises providing a first outer mold and a second outer mold, and an inner mold therebetween. The first outer mold and the inner mold define a first mold space, and the second outer mold and the inner mold define a second mold space. The method further comprises molding the viewing elements, the plurality of arms and the optic as a single piece by filling the first and second mold spaces with a material, such that the first viewing element and the plurality of arms are formed in the first mold space and the second viewing element is formed in the second mold space. The method further comprises removing the first and second outer molds from the lens while the inner mold remains between the viewing elements, and removing the inner mold from between the viewing elements while the viewing elements remain interconnected.

International Classification:
A61F 2/16
US Classification:
606107
Abstract:
An injector for inserting an intraocular lens into an eye includes a lumen. The lumen can include a terminal portion at a distal end and a proximal portion juxtaposed with the terminal portion. An injector plunger can be disposed within the lumen for generating a driving force on the intraocular lens. The injector can include a lens frictional force that has a first value when the lens is at a first location within the proximal portion and a second value when the lens is at a second location within the terminal portion. The first value can be smaller than the second value. In some embodiments, the lens frictional force increases abruptly from the first value to the second value as the lens approaches the distal end of the lumen.
