Abstract
Methods and apparatus for an intraocular lens with a proofed surface are disclosed. The proofed surface functions as a barrier to fluid diffusion inside the material and within vacuoles. By preventing the interstitial filling of fluid, the formation of spots inside the polymer matrix is inhibited or reduced. The proofed surface of the intraocular lenses is a highly stable re-assembled surface without any coating or grafting.
