ABSTRACT:
A method for minimizing excess intraocular pressure during a phacoemulsification procedure in which eye tissue is fragmented and aspirated from the eye through a needle with irrigation fluid includes controlling the rate of irrigation fluid flow rate upon partial or total occlusion of the needle. For example, the method may include the steps of: introducing irrigation fluid into an eye at a selected rate; thereafter aspirating said irrigation fluid while introducing the irrigation fluid at a higher rate; during phacoemulsification and aspiration of fragmented eye tissue through the needle, introducing the irrigation fluid at the higher rate; and upon partial occlusion of the needle with fragmented eye tissue, introducing the irrigation fluid at a still higher rate.
