OBJECTIVE: To describe the methodology of the Comparing the Effectiveness of Phacoemulsification + Endoscopic Cyclophotocoagulation Laser and Phacoemulsification Alone for the Treatment of Primary Open Angle Glaucoma in Patients with Cataract (CONCEPT) study, a randomized controlled trial.
DESIGN: Double-masked, randomized controlled trial.
SUBJECTS, PARTICIPANTS, AND/OR CONTROLS: Participants will be recruited from 5 United Kingdom-based centers. One hundred and sixty eyes with a diagnosis of primary open-angle glaucoma and visually significant cataract will be included. Eighty eyes will be randomized to undergo cataract surgery alone and eighty to undergo cataract surgery with endoscopic cyclophotocoagulation (ECP).
METHODS: The baseline diurnal washout intraocular pressure (IOP) will be measured. The participants will be randomized to undergo cataract surgery alone or cataract surgery with ECP upon completion of uncomplicated cataract surgery. At the 1- and 2-year post surgery follow-up visits, the measurements of washout diurnal IOP will be repeated.
MAIN OUTCOME MEASURES: Diurnal washout IOP, use of glaucoma medications, and adverse events.
CONCLUSIONS: We described the methodology of the first randomized controlled trial comparing cataract surgery alone with cataract surgery combined with ECP in the context of patients with primary open-angle glaucoma and symptomatic cataract.
