US Patent:

6774178, Aug 10, 2004
Filed:

Dec 14, 2001
Appl. No.:

10/017549
Inventors:

Richard Charles Turek - Atlanta GA
Jacalyn Mary Schremmer - Atlanta GA
Assignee:

Novartis AG - Basel
International Classification:

C08L 8307
US Classification:

524858, 528 32, 528 33, 540139, 540140, 523106, 523107, 524588, 524544, 524700, 526279, 8507, 264299, 264 132
Abstract:

The invention relates to ophthalmic molding formulations and to tinted, high Dk ophthalmic moldings. This invention also relates to a method for making a tinted ophthalmic molding. The method comprises: (a) providing a polymer precursor having cross-linkable or polymerizable groups; (b) providing a pigment dispersion comprising an inorganic or organic pigment and a dispersing agent; (c) mixing the pigment dispersion with the polymer precursor to form a tinted prepolymer mixture; (d) dispensing the tinted prepolymer mixture into a mold; and (e) forming a tinted ophthalmic molding from the tinted prepolymer mixture, the molding comprising a polymer matrix having the pigment entrapped therein. With this method, tinted ophthalmic moldings, particularly edge-to-edge soft, tinted contact lenses having improved properties, are prepared with an improved efficiency.

International Classification:

B32B 904
US Classification:

428447, 528 32, 523106, 523107, 524588, 526279, 540139, 540140, 427 224, 427162
Abstract:

An ophthalmic lens suited for extended-wear periods of at least one day on the eye without a clinically significant amount of corneal swelling and without substantial wearer discomfort. The lens has a balance of oxygen permeability and ion or water permeability, with the ion or water permeability being sufficient to provide good on-eye movement, such that a good tear exchange occurs between the lens and the eye. A preferred lens is a copolymerization product of a oxyperm macromer and an ionoperm monomer. The invention encompasses extended wear contact lenses, which include a core having oxygen transmission and ion transmission pathways extending from the inner surface to the outer surface.
