Abstract: Objective To study the biocompatibility of contact lens material for human cornea prepared in our department. Methods Biological properties of the material were assessed by cytotoxicity,haemolysis and protein aggradation. Results The material had no toxicity for HEFC. The haemolysis rate was eligibility(1.62%). Anti-protein-aggradation was quite good. Conclusion The contact lens material by our department possesses quite good biological properties.
