International Classification:

B29D 1100

US Classification:

264 11, 264 25, 264 27, 425808, 451 42

Abstract:

An arbor for lathe cutting lenses, especially contact lenses, from a blank, is designed for the mounting of a lens mold with a cast lens blank therein during lathing of the lens blank. The arbor is made in a manner to ensure the lens mold is axially aligned with the arbor. The arbor can be reused for lathe cutting of multiple lens blanks retained in their respective lens molds.

US Classification:

264/001360, 264/040100, 264/489000

Abstract:

The present invention relates to an improved method of manufacture of molded polymeric devices using variable frequency microwaves. Molded polymeric devices include, for example, contact lenses, corneal rings, intraocular lenses and drug delivery devices such as anterior or posterior chamber inserts. Contact lenses include soft and rigid gas permeable contact lenses as well as, lens blanks lathed into finished contact lenses. Molded polymeric devices further include medical devices such as prosthetics including hip joints. According to the present invention, a mold having a cavity the shape of the desired molded polymeric device, the cavity containing a composition comprising one or several monomers having double polymerizable bonds, is placed in a microwave chamber. The mold can be plastic, glass, ceramic or metal. Plastic is preferred. The mold is then swept with at least one range of microwave frequencies to polymerize the composition, thus forming the molded polymeric device. A range of frequencies includes a central frequency selected to rapidly heat the composition. A range is selected to generate a plurality of modes within the chamber. Sweeping is performed at a rate selected to avoid damage to the polymer formed and the mold.

B29D 1100

US Classification:

351177

Abstract:

A method for forming a contact lens comprising subjecting a soft contact lens impregnated with a polymerizable liquid composition which may be polymerized in said lens to render said lens relatively rigid and which may be polymerized upon exposure to radiation with radiation in a selected manner so as to render selected portions of said lens relatively rigid.

International Classification:

B29D 1100

US Classification:

264 1

Abstract:

Apparatus for and method of forming ophthalmic lenses and/or semi-finished lens blanks including those of the eye contact type. The apparatus includes molds having cooperating first and second members each of which includes a longitudinal axis and a mold surface which is symmetrical with respect to such axis. In one embodiment these mold members or halves also include cooperating surfaces which, in operation and in cooperation with the selected lens material, both align the respective mold axes and axially position the mold surface of the first member with respect to the mold surface of the second member to thereby form the desired lens mold cavity. Further, each of the assembled molds also includes an annular reservoir which surrounds the mold cavity and is defined by surfaces provided on the first and second mold members. This reservoir is connected to the mold cavity via an annular restriction. In one embodiment this restriction is defined by the cooperating aligning surfaces provided on the first and second mold members.

Inventors:

Richard J. Wrue - Greece NY

Assignee:

Bausch & Lomb Incorporated - Rochester NY

International Classification:

B08B 1102

US Classification:

1510492

Abstract:

An apparatus for the cleansing of contact lenses comprising a housing for containing a lens divided into a top portion and a bottom portion. The top portion may be joined or removed from the bottom portion. In addition, the top portion is movable while joined with the bottom portion and vice-versa. Within the top and bottom portions are scrubbing pad means which are used to scrub a contact lens when the top portion of the housing is moved in relation to the bottom portion. An offset dome is built into the bottom portion which causes the lens to migrate within the housing during scrubbing, thereby thoroughly cleansing all portions of the lens.
