Disclosed in embodiments herein is a method of synthesizing device forming monomers using N-(Vinyloxycarbonyloxy)succinimide.

System for synthesis of device forming monomers

A lens with a colored portion is composed of a lens-forming polymer having a front lens surface and a back lens surface. A colorant is applied to at least one of these surfaces, and these surfaces may be coated with a coating layer composed of a material different than the lens-forming polymer. In the case of a cosmetic contact lens, the colorant may be applied in an annular ring pattern corresponding to an iris, so that the colorant pattern masks and changes the apparent color of the natural iris when the contact lens is worn.

Lens with colored portion and coated surface

Improved silicone-containing hydrogels are disclosed with enhanced wettability comprising a silicone-containing monomer, hydrophilic monomers, and a relatively non-polar ring-containing monomer able to be converted to a highly polar amino acid upon hydration.

Wettable silicone hydrogel compositions and methods for their manufacture

Branched cycloalkyl methacrylate monomers, such as t-butylhydroxycyclohexyl methacrylate, are polymerized with hydrophilic monomers and crosslinking agents to produce compositions for shaped biomedical devices, including soft contact lenses. Such copolymers have high oxygen permeability and good mechanical properties.

Polymer compositions for contact lenses

Branched alkylhydroxycycloalkyl methacrylate monomers, such as t-butylhydroxycyclohexyl methacrylate, are polymerized with hydrophilic monomers and crosslinking agents to produce compositions for shaped biomedical devices, including soft contact lenses. Such copolymers have high oxygen permeability and good mechanical properties.

Polymeric materials with high oxygen permeability and low protein

Inclusion of carbonyl modified amino acid monomers in polymeric compositions for biomedical applications, including contact lenses, increases the water content and oxygen permeability of the polymer without significant changes in other desirable properties of the polymer.

Alpha, beta-unsaturated carbonyl modified amino acid monomer and

The surface wetting characteristics of polysiloxanes prepared from monomeric polysiloxanes endcapped with activated unsaturated groups and modulus modifiers are improved by the inclusion of small amounts of an N-alkenoyl trialkylsilyl aminate. The improved polymeric compositions can be used to form hard, gas permeable contact lenses and other biomedical devices.

Polysiloxane composition with improved surface wetting characteristics

Low N-vinyl lactam content copolymers are cross-linked with resonance free di(alkene tertiary amine) cyclic compounds to obtain biomedical devices, including soft contact lenses, which have good oxygen permeability and mechanical properties.

Low N-vinyl lactam content based biomedical devices

N-vinyl lactam monomers and comonomers are cross-linked with resonance free di(alkene tertiary amine) cyclic compounds to obtain biomedical devices, including contact lenses, which have high oxygen permeability and good mechanical properties.

N-Vinyl lactam based biomedical devices

Monomeric polysiloxanes endcapped with activated unsaturated groups are copolymerized with polycyclic modulus modifiers and tear film stabilizers to form hard, gas permeable, polysiloxane contact lenses and other biomedical devices.
