1. 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.
