  • Biocompatible polymeric materials, methods of preparing such materials and uses thereof
    Patent number: 5993796
    Abstract: The present invention is directed to a biocompatible polymeric material and methods of making prepared by forming a mixture of collagen, a water-soluble ethylenically unsaturated compound and a cross-linking agent at a temperature of 30.degree. C. to 42.degree. C.; adjusting the pH of the mixture to 3.2 to 5.0; and polymerizing the mixture. The resulting material is rinsed in a physiologic solution at a temperature of 25.degree. C. to 80.degree. C. The resulting polymeric material has a modules of elasticity in the range of 10 to 27.times.10.sup.5 N/m.sup.2. Mechanical strength of the polymeric material is 20 to 100 times greater than polymeric material prepared by known methods. The material is optically transparent and is characterized by 95% or more light transmission in the visible spectrum and by resolution of 200 lines per mm for a +20D intraocular lens. The material is characterized by low protein absorption of about 0.1.times.10.sup.-3 .mu.
