Patients were administered with a retro-bulbar block and treated with the MicroPulse P3 glaucoma device (IRIDEX IQ810 Laser Systems) at 2–2.5 watts with a duration of 90 seconds per hemisphere at a 31.3% duty cycle. In cases requiring re-treatment, the same treatment parameters were used with an increase in power up to 3 watts.
Patients were prescribed topical corticosteroids in the operative eye post-procedurally with a 1-month taper and IOP-lowering medications were withdrawn as appropriate. Patients were seen postoperatively on day 1, week 1, and months 1, 3, 6 and 12.
All patients received follow-up care for at least 1 year. Outcome measures included postoperative IOP and number of postoperative IOP medications required.
