Fig. 14. Two argon laser iridectomies were performed in this phakic eye for primary angle closure. These are done at the 2 o'clock and 10 o'clock positions, avoiding 12 o'clock in order that bubbles and dispersed pigment would not obscure visibility during the procedure. Two procedures, rather than one, are done so that in case one happens to become occluded, the other remains to prevent pupillary block and angle closure.
