First Claim
Patent Images
1. A non-invasive method for focal non-invasive transcleral destruction of living human eye tissue, comprising the steps of:
- (a) providing a hollow probe having a distal end and a proximal end;
and, at said distal end a first aperture to receive a conductive electrode and means for filling said probe with a neutral solution;
and, at said proximal end a second aperture of predetermined diameter;
(b) connecting said conductive electrode to a constant current supply having a positive terminal and a negative terminal;
(c) filling said probe with a neutral solution using said filling means;
(d) adjusting said constant current supply to a current in the range of between about 1.5 milliamps to about 8.0 milliamps;
(e) repeated placement of said proximal end of said probe onto a scleral surface of a human eye proximate to target eye tissue at a plurality of locations; and
(f) each of said placement remains for a predetermined duration.

Abstract
A non-invasive method for focal transcleral destruction of living human eye tissue. The method includes providing a conical-shaped probe, filled with a neutral saline solution and having inserted therein an electrode connected to the positive terminal of a constant current supply. The narrow aperture ends of the probe is lowered onto the conjunctiva overlying the target tissue, in about 20-30 locations with a current in the range from about 3.0-4.0 milliamps for about 30 seconds to 5 minutes at each location.
