摘要:
An eye lens material preventing protein adsorption is manufactured by reacting in a reaction medium of either water, an organic solvent, or a water/organic solvent mixture an eye lens material having OH groups with a phosphorylcholine group-containing compound of formula (1), thereby forming an acetal bond according to formula (2) which covalently bonds the phosphorylcholine group-containing compound to a surface of the eye lens material.
