ABSTRACT:
An apparatus in which a deformable or compressible intraocular lens can be received and staged for insertion into a patient's eye. The apparatus has an elongated compression chamber with proximal and distal ends and a longitudinal passageway, having an inner surface, extending between the ends. The portion of the passageway adjacent to the proximal end forms a loading area in which the passageway gradually decreases in size for causing an intraocular lens to be deformed or compressed as the lens is moved along the passageway. A staging area having a top and bottom passageway wall, communicates with the loading area with the passageway wall including alignment means for retaining the intraocular lens in a deformed or compressed condition. A portion of the passageway is sized to retain the intraocular lens in the deformed or compressed condition. A portion of the passageway defining the loading area comprises a surface which includes an opening and a slot or groove for permitting withdrawal of forceps used for pushing the intraocular lens through the loading area and into the staging area for deforming or compressing the lens.
