Abstract
This invention provides a new method of preparing intraocular lenses for implantation which comprises folding, stretching, rolling, compressing or otherwise reconfiguring the lens to reduce the profile of the lens in at least one dimension and dehydrating the lens in that shape. The thus prepared artificial intraocular lens may be surgically implanted in the eye through a small incision where it will be rehydrated in situ.
