Phacogoniotomy lowered eye pressure as effectively as phacotrabeculectomy after 3 years.

Purpose

To evaluate the 3-year efficacy and safety of phacogoniotomy versus phacotrabeculectomy for advanced primary angle-closure glaucoma (primary angle-closure glaucoma) with cataract.

Methods

Were randomized 1:1 to undergo either phacogoniotomy (65 eyes) or phacotrabeculectomy (59 eyes).

n = 65 eyes
Results

checking eyes' pressure control, phacogoniotomy matched the other surgery equally well

MD -0.37 (95% CI -1.32 to 0.58)
null 0

0.58
CI crosses the null - not significant
More results

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.

More results

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).

Conclusion

At 3 years, phacogoniotomy remained non-inferior to phacotrabeculectomy in IOP reduction for advanced primary angle-closure glaucoma with cataract.
