Three-year outcomes of phacogoniotomy versus phacotrabeculectomy for advanced primary angle-closure glaucoma with cataract: A randomized controlled trial.

At 3 years, phacogoniotomy reduced mean IOP from 40.2 (10.3) to 14.1 (2.4) mmHg (-26.1 [10.4] mmHg reduction); phacotrabeculectomy, from 39.7 (9.3) to 14.4 (2.5) mmHg (-25.3 [9.2] mmHg reduction).

Complete (78.3% vs 89.8%; P = 0.13) and qualified (90.0% vs 91.8%; P > 0.999) success rates were comparable.

Hypotensive medications declined in both groups (phacogoniotomy: 2.1 [1.2] to 0.2 [0.6]; phacotrabeculectomy: 2.1 [1.3] to 0.0 [0.2]; P = 0.06 for 3-year difference).
