SCHEIE et al1 have justifiably popularized cataract aspiration for young patients. Technique variations2-4 still require movement of a needle inside a child's eye. Maximum control of the aspirating needle while manipulating a syringe is difficult. A remote syringe on the end of a polyethylene tube handled by an assistant is better; but removes the surgeon from full control.
A delicate, foot-operated suction control is available (Fig 1 and 2). Existing operating room suction is used and can be varied in extremely small increments. Readily available, sterile, intravenous tubing with a 19 gauge needle gives the surgeon an easily controlled instrument plus a free hand (Fig 3). Making the corneoscleral incision 2 mm instead of 1 mm allows irrigation and iridectomy with little added risk.
Wesley H. Bradley, MD, introduced us to this device used successfully in stapes surgery.
The foot-operated suction control is available from the Cadogan Engineering
