Appl. No.:

09/698418

Inventors:

Madhu Ayyagari - Fairport NY
Mahendra P. Nandu - Rochester NY
Erik M. Indra - Webster NY
Alan J. Braun - Livonia NY

Assignee:

Bausch Lomb Incorporated - Rochester NY

International Classification:

B29D 1100

US Classification:

264 26, 134901, 528480, 528496

Abstract:

A method of extracting residual materials from a polymeric, ophthalmic biomedical device, such as a contact lens, by using a mixture comprised of a primary solvent, such as carbon dioxide, and a polar co-solvent, such as isopropanol. By exposing the device to the co-solvent, the device expands. By pulsing or varying the concentration of the polar co-solvent in the mixture, the lens dimensions vary accordingly. When the lens is extracted while retained in a mold, the changes in lens dimensions causes the lens to be released from the mold.

Filed:

Sep 28, 1993

Appl. No.:

8/127937

Inventors:

Alan J. Braun - Livonia NY

Assignee:

Bausch & Lomb Incorporated - Rochester NY

International Classification:

B08B 304

US Classification:

206 51

Abstract:

A case for disinfecting, cleaning or storing contact lenses is described that provides a venting system for discharging gas therefrom without significant liquid discharge. The case includes a cap securable to a container, having an inner surface including a hollow pedestal with its open distal end extending into the container. The end of the pedestal adjacent the inner cap surface encompasses an aperture through said cap for venting and discharging of gas to the environment. A gas and liquid impermeable gasket fits inside the hollow end of the pedestal adjacent the aperture area, permitting venting of gas but not liquid through the adjacent aperture. A support for holding and positioning contact lenses in the container includes a post that is fitted into the distal end of the hollow pedestal, wherein the pedestal and post are provided with a channel therethrough to permit gas to escape from the container through the gasket and adjacent aperture.
