| titleOfInvention | Extended wear ophthalmic lens |
| abstract | An ophthalmic lens comprising an inner and outer surface, where the inner surface is adapted to rest immediately adjacent to the human cornea having the following properties: (a) an oxygen permeability from the inner to the outer surface in an amount sufficient to prevent sufficient corneal swelling during a period of extended wear, being at least about 70 barrers/mm; (b) ophthalmic compatibility during a period of extended, continuous contact with the ocular environment; and (c) ion or water permeability in an amount sufficient to allow lens movement on the eye and to sustain corneal health and wearer comfort, the sodium ion permeability characterised by either (1) an lonoton lon Permeability Coefficient of greater than about 0.2 x 10-6 cm2/sec or (2) an lonoflux Diffusion Coefficient of greater than about 1.5 x 106 mm2/min. A method for using the lens, a method for forming the lens, a method for screening lens suitable for extended wear, a method for forming a molded polymeric article and a polymer composition having good optical clarity and high oxygen permeability comprising: (a) about 5 to about 94 dry weight percent of a macromer having the formula pictured; wherein: R1 and R2 are selected from C1-C6 alkyl, R3, R4, R5, and R6 are selected from C1-C6 alkylene, R7 and R8 are selected from linear or branched alkylene and bivalent cycloalkylene, R9, R10, R11, and R12 are selected from C1-C2 alkylene, R13 and R14 are selected from C1-C6 alkylene, R15 and R16 are selected from linear or branched lower alkenylene, m and p, independently of one another, are about 3 to about 44, and n is about 13 to about 80, wherein said macromer has a number-average molecular weight of 2000 to 10,000; (b) about 5 to about 60 weight percent of an acrylated or methacrylated siloxane monomer; (c) about 1 to about 30 weight percent of an acrylate or methacrylate monomer; and (d) 0 to 5 weight percent cross-linking agent; wherein said weight percentages are based upon the dry weight of the polymer components |
