Pre-Op

Preoperatively, careful goinoscopy should be done to visualize the trabecular meshwork and plan the treatment area. The procedure is done with the Lumenis Selecta laser system.

Preoperative medications consists of a drop each of lopidine or Alphagan and topical anesthesia. A Goldman, three-mirror goniolens is placed on the eye with methylcellulose. The aiming beam is focused onto the pigmented trabecular meshwork.

During

Treatment is done in single-burst mode, placing 50 ± 5 contiguous, but not overlapping, 400-micrometer laser spots along 180 degrees. Bubble formation is monitored with each pulse. In cases with significant variation in trabecular pigmentation, the pulse energy is decreased if bubble formation occurred as described above.

Post-Op

After laser treatment, prednisolone acetate 1% is administered and continued n the treated eye four times daily for four to seven days.
