ABSTRACT:
An intraocular lens is treated to form a modified passivated outer surface for reducing or eliminating biological reactions of inflammatory origin when the lens is implanted into an eye. The lens is formed from a conventional lens implant material, such as polymethyl methacrylate (PMMA), which is treated as required to create an outer surface region including a relatively high density of hydroxyl groups. This outer surface region is reacted with a selected fluorocarbon carried in a solution with a primer including bonding agents for bonding the fluorocarbon with respect to the hydroxyl groups, thereby creating a thin, substantially inert or passivated outer surface resistant to irritative reaction with tissue or cells when the lens is implanted into the eye.
