Outcomes of phacoemulsification combined with ab interno trabeculotomy: stratified by incision extent, glaucoma severity, and baseline number of medications.

Mean (SD) IOP decreased from 17.2 (4.9) mmHg at baseline to 13.1 (3.5) at 12 months and 13.1 (3.9) at 24 months, and medications decreased from 2.6 (1.3) to 2.0 (1.3) at 12 and 24 months.

In the multivariable Cox model, ≥6 clock hours was not significantly associated with surgical failure compared with <6 clock hours (adjusted HR, 1.14; 95% CI, 0.85 to 1.53; P = 0.367).

Higher baseline medication burden was associated with worse success across IOP-defined criteria.
