An IOL compression chamber for folding an IOL includes a hollow chamber having a loading area, a staging area and a distal tip. The loading area has a distally extending slot in the wall which allows for easy removal of a forceps holding the IOL from the chamber following insertion of the IOL into the chamber with the forceps. The staging area holds the IOL in a folded state until the chamber is placed into an IOL insertion instrument having a plunger which forces the IOL distally out of the staging area and into the eye through the distal tip.

A process of removing flash from a molded intraocular lens includes a step of tumbling the lens body in a tumbling media. The tumbling media includes a mixture of 0.5 mm diameter glass beads and 1.0 mm diameter glass beads, alcohol and water. This process applies to single piece and multipiece IOLs.

IOL tumbling process

Apparatus for preparing an intraocular lens for insertion

Silicone IOL tumbling process

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.
