An irrigating probe for providing a flow of liquid to the trabecular meshwork of the eye has a first, guide prong that contacts the cornea to position a second, irrigator prong proximate the trabecular meshwork. The irrigator prong has at least one outlet port communicating with an internal flow channel which, in turn, communicates with a liquid supply providing a steady or a pulsed flow.
