The present form of irrigation device used to maintain the chamber
in eye surgery is difficult to insert (screws in) and difficult
to remove (unscrews). In addition, the time and technique involved
in the insertion and removal process increases trauma recovery

The BCM-2C features an oval shaped
tip with three single direction fins on its anterior
and posterior surfaces. When inserted, the fins securely
engage the corneal stroma, preventing the tip from
becoming dislodged. To withdraw, the BCM-2C is simply
rotated 90° to disengage the fins and retract.
In addition, the flared area just after the fins serves
to seal the incision and limit advancement into the
anterior chamber. The combination of these features,
along with the high flow capability (over 100cc/min.),
provides excellent globe pressurization with minimal
