Abstract

Every month, 4–5 new patents for contact lens materials appear in the international chemical literature. However, rarely do more than one or two new materials reach the market during the year. In addition, almost all new materials are minor variations of the basic lens polymers that have been available for the last 10 to 15 years. The problem which keeps the new materials from entering the marketplace is not a lack of demand for improved materials, but that most of the potential polymers satisfy only one or two of the requirements for clinical success. This paper will discuss 20 aspects of lens polymers which must be considered by investigators hoping to bring their new polymer to the ophthalmic market.
