ABSTRACT:
Collapse of the cornea into the cavity formed when material such as the lens is removed from an eye in the irrigation-aspiration method is minimized by incorporating a pressure responsive, variable flow resistance element in the aspiration line of the irrigation-aspiration apparatus. A preferred pressure responsive, variable resistance element is a length of thin walled tubing which is easily collapsed to smaller flow path area in response to increasing negative pressure in the aspiration line.
