A device for inserting a flexible membrane into an eye which includes a tubular member with an passage and a plunger movably received in the passage. The passage has an open distal end adapted to be received into an eye for implantation of a lens, and a staging area for initially receiving the lens into the passage. The tubular member includes an opening to permit loading of a lens into the staging area, and a cover movable between an open position to expose the staging area and a closed position to enclose the staging area. The distal end of the plunger has a visual indicator which provides a contrasting image as compared to the staging area. The visual indicator enables the surgeon to easily see whether the distal tip of the plunger is improperly positioned in the staging area before loading the lens.

Device for inserting a flexible intraocular lens

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.

Apparatus for preparing an intraocular lens for insertion

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.
