Abstract
A partially hydrated lens is provided for implantation into a cornea. The partially hydrated lens has a water content less than the water content of the cornea, resulting in an osmotic pressure differential between the lens and the cornea which improves adhesion between the lens and the corneal tissue. It also causes the lens to expand and flatten when implanted, and to [naturally center itself while flattening.] In the preferred embodiment of the invention, the lens is maintained in its partially hydrated state by storage in a hypertonic hydration medium.
