OBJECTIVE: The objective of this study was to report medium-term outcomes of a novel combination of phacoemulsification with transscleral cyclophotocoagulation (phaco-TCP) compared with combined phacoemulsification and endoscopic cyclophotocoagulation (phaco-ECP) in patients with uncontrolled or suboptimally controlled glaucoma and coexisting cataract. MATERIALS AND METHODS: Retrospective case series of 80 consecutive patients with a minimum of 12 months of follow-up. In total, 46 eyes underwent phaco-ECP and 34 phaco-TCP. Success was defined as intraocular pressure (IOP) between 6 and 21 mm Hg with ≥20% reduction from preoperative IOP (with no increase in ocular hypotensive medications or further glaucoma surgery). Secondary outcomes were change in IOP, number of ocular hypotensive medications and safety. RESULTS: The mean follow-up was 32.6 ±10.3 months. Preoperative clinical characteristics were similar in both groups. At latest follow-up, success rate was greater with phaco-TCP than phaco-ECP (67.6% and 47.8%, P=0.037). IOP was also significantly lower after phaco-TCP (14.88±5.57 mm Hg, from 22.62±6.52 mm Hg) than phaco-ECP (18.07±6.72 mm Hg, from 22.83±7.88, P=0.0273). Ocular hypotensive medications required reduced similarly after phaco-TCP (from 3.38±0.88 to 2.65±1.04 medications, P=0.0012) and phaco-ECP (from 3.07±0.929 to 2.63±1.42 medications, P=0.0108). There were no cases of hypotony or reduction in vision related to glaucoma with either surgical intervention and a similar proportion required further glaucoma surgery (phaco-ECP 15.2%, phako-TCP 5.9%, P=0.2884). CONCLUSIONS: Phaco-TCP appears more successful in controlling IOP than phaco-ECP with similar safety. Further investigation is warranted of this newly proposed combination which may be particularly useful where access or experience with ECP or other minimally invasive glaucoma surgery is limited.
