A technique can be used increase the flow of fluid through the trabecular meshwork. The fluid pulses can be focused, thereby perforating the trabecular meshwork, or applied over a larger area so as to stimulate the trabecular meshwork for improved fluid transport. In addition, the pulses of the irrigating fluid can clean away material, such as iris pigment, that may be blocking or clogging the trabecular meshwork. Such a technique may be practiced using the tip of the present invention and commercially available surgical handpieces.
