Outcomes of phaco-KDB surgery unaffected by prior laser trabeculoplasty

Previous treatment with laser trabeculoplasty (LTP) does not influence the outcomes of subsequent phacoemulsification combined with Kahook Dual Blade goniotomy (phaco-KDB) in patients with open-angle glaucoma or intraocular hypertension, according to a study.

The study included 111 patients who had undergone LTP, which included argon laser trabeculoplasty (ALT) and selective laser trabeculoplasty (SLT), and 139 patients who had not.

Surgical success rates for phaco-KDB were 82.9% in the LTP-treated group and 88.5% in the non-LTP-treated group (P = 0.20). Reductions in intraocular pressure and medications were similar across both groups. In addition, among the LTP-treated patients, those with successful LTP outcomes had a phaco-KDB success rate of 80.7%, while those with unsuccessful LTP outcomes had a success rate of 83.0% (P = 0.765).

The study concluded that previous LTP treatment does not predict the outcome of phaco-KDB surgery.
