Abstract
Apparatus and non-invasive method for focal transcleral destruction of living human eye tissue. The apparatus includes a pair of conical-shaped probes, each probe filled with an ionic probe solution and having therein an electrode connected to a constant current supply. The method includes lowering the narrow aperture end of the probes onto the conjunctiva overlying the target tissue, each probe being approximately 90.degree. apart from the other about the eye surface. The probes of the invention have opposite polarity to enable transfer of ions between the probes. Electrodes are of appropriate conductive materials.
Claims7
A non-invasive method for focal non-invasive transcleral destruction of living human eye tissue, comprising the steps of:
- A. providing a constant current supply having a positive terminal and a negative terminal;
- B. providing a pair of hollow probes, each of said probes having a distal end and a proximal end, and a first aperture at said distal end of each hollow probe to receive a conductive electrode of predetermined composition and means for filling said probe with a predetermined solution;
- C. connecting said conductive electrode of one of said probes to said positive terminal, defining a first probe, and connecting said conductive electrode of the other of said probes to said negative terminal, defining a second probe;
- D. filling each of said probes with a solution of predetermined ionic concentration;
- E. adjusting said constant current supply to a predetermined current;
- placing, substantially simultaneously, said proximal ends of said probes repeatedly onto a surface of a human eye proximate to target eye tissue at a plurality of locations;
- and
- G. maintaining movement of said proximal ends for a predetermined duration.
