Ophthalmic Surgery And Dry Eyes

Chondroitin sulfate is used as a viscoelastic substance to protect and lubricate cells and tissues during ophthalmic surgery, as well as to preserve corneas before transplantation (Larson et al 1989, Liesegang 1990). In a double-blind crossover study of 20 subjects, 1 % chondroitin sulfate was found to be equally as effective as polyvinyl alcohol artificial tear formulation and 0.1% hyaluronic acid in reducing itching, burning and foreign body sensation in people with keratoconjunctivitis sicca (Limberg etal 1987).
