Abstract
A non-invasive method for treatment of glaucoma by selective ablation of sclera of a living human eye. The method includes providing a slit lamp laser system including a source of pulsed laser light and a gonio lens adapted to withstand pulsed laser light having energy of greater than 100 mJ pulse. The method further includes focusing the laser light on the sclera, and adjusting the light to a spot diameter of between 100 and 300 microns, a pulse width of between 1 and 30 microseconds, a pulse energy of between 75 andn 250 mJ, and a cone angle of between 8 and 15 degrees. The sclera is then repeatedly illuminated with single pulses of laser light until the sclera is perforated.
