Abstract

An irrigating tip have a flattened or oval shape more easily fits into the anterior chamber angle, thereby allowing more effective delivery of the pulses of balanced salt solution to the trabecular meshwork.

Claims

1. An irrigation tip, comprising:

a) a proximal shaft portion, the proximal shaft portion being generally circular in shape;

b) a distal shaft portion, the distal shaft portion being fluidly connected to the proximal shaft portion and being generally oval or elliptical in shape; and

c) a distal tip on the distal shaft portion.

2. An irrigation method, comprising:

a) providing an irrigation tip have an oval or elliptical distal end;

b) placing the distal end into an eye adjacent to an anterior chamber angle; and

c) causing repeated pulses of an irrigating fluid to strike a trabecular meshwork.

3. The method of claim 2 wherein the pulses perforate the trabecular meshwork.

4. The method of claim 2 wherein the pulses stimulate the trabecular meshwork.

5. The method of claim 2 wherein the pulses clear away material blocking or clogging the trabecular meshwork
