Deformable lens insertion apparatus and method

摘要

An apparatus for insertion of intraocular lenses into the eye. In one embodiment, the apparatus includes a loading chamber and an injection portion. The loading chamber has a proximal end and a distally extending opening. The loading chamber defines a first lumen and is adapted to receive an intraocular lens in an unfolded state at the distally extending opening and to fold the intraocular lens and maintain the intraocular lens folded as the intraocular lens is placed in the first lumen. The injection portion defines a second lumen aligned with the first lumen and is adapted to receive the folded intraocular lens from the first lumen in the second lumen. The injection portion has an open distal end through which the folded intraocular lens from the second lumen passes to be inserted into an eye. The intraocular lens may be either pushed out, or pulled through the distal end into the eye.
