Objectives: To report the clinical outcomes of FP7 Ahmed Glaucoma Valve (AGV) implant in refractory glaucoma cases. Study Design: It was a prospective, non-comparative, interventional case series, conducted at glaucoma clinic of Al-Shifa Trust Eye Hospital, Pakistan between July 2016 to June 2018. Subjects and Methods: All refractory glaucoma cases, which were treated with Ahmed Glaucoma Valve implant and completed at least one year follow up were included in this study. All cases were performed by a single surgeon using a standard technique. Pre-operative and post-operative visual acuity status and intraocular pressures were recorded as well as any complications encountered during the first post-operative year. All the data was entered on proformas and statistical analysis was done using SPSS version 21.0. Results: A total of 34 eyes of as many patients were included. Pre-operative mean IOP was 29.76 (+-8.14) mm of Hg while post-operative mean IOP was 14.97 (+-4.65) mm of Hg. At oneyear post-operative period, IOP was successfully controlled in 19 (55.88%) eyes without any additional antiglaucoma medicines, 14 (41.17%) eyes required additional post-operative anti glaucoma medicines while one eye underwent selective diode laser cycloablation. Hypertensive phase was noticed in 24 (70.58%) eyes which was managed by different methods. Post-operative complications included transient hypotony in 6 (17.64%) eyes, Choroidal detachment in 4 (11.76%) eyes, Tube exposure in 2 (5.88%) eyes and iris incarceration in tube in 1 (2.94%) eye. Drop in visual acuity was experienced in 3 (8.82%) eyes. Conclusion: The overall success rate of FP7 AGV is comparable to that of prior studies using different models of AGV. The incidence of serious and long-term postoperative complications is low after FP7 AGV insertion.
