Abstract

The invention provides a method of protecting an eye-contacting part of an ophthalmic instrument against contamination and for preventing cross-infection of patients from an eye-contacting part of an ophthalmic instrument. The method comprises covering the said part of the instrument with an adhesive, sterile or sterilisable, sheet barrier. The sheet barrier comprises a substantially optically transparent biocompatible barrier layer and a substantially optically transparent adhesive hydrogel layer. The adhesive hydrogel layer comprises a plasticised three-dimensiona) matrix of cross-linked polymer molecules selected from polymers and copolymers of: 2-acrylamido-2-methylpropane sulphonic acid or a substituted derivative thereof or a salt thereof; acrylic acid or a substituted derivative thereof or a salt thereof; a polyalkylene glycol acrylate or a substituted derivative thereof; a polyalkylene glycol methacrylate or a substituted derivative thereof; acrylic acid (3-sulphopropyl) ester or a substituted derivative thereof or a salt thereof; diacetone acrylamide; a vinyl lactam; an optionally substituted Nalkylated acrylamide; an optionally substituted N,N-di-alkylated acrylamide; and/or N acryloyl morpholine or a substituted derivative thereof; in the case of copolymers, said copolymer being formed optionally with one or more further comonomer.
