Abstract
A system for collapsing the lens loops of an intraocular lens in preparation for insertion of the lens into a human eye and forming and maintaining the lens loops in a collapsed position during the lens insertion operation. The system includes an apparatus for mating the intraocular lens with an incapsulating structure such as a wafer fabricated from viscoelastic material. The device is designed in a manner which causes the lens loops of the intraocular lens to collapse as the lens is inserted into the incapsulating structure during the mating process. In a preferred embodiment, the device may comprise a rotor element mounted on a baseplate for supporting the intraocular lens beneath the incapsulating structure, whereby the lens can be rotated or "dialed" into the incapsulating structure.
