Purpose: To describe a modified surgical approach with anterior vitrectomy, phacoemulsification (phaco) cataract extraction and irido-zonulo-hyaloid-vitrectomy (IZHV) in protracted acute angle closure crisis (AACC).
Patients And Methods: Non-comparative, retrospective case series including 21 eyes in 19 consecutive cases of protracted AACC, which persists for at least 7 days despite maximal medical and laser therapies, were included in this study. All patients underwent a modified surgical procedure with anterior vitrectomy, phaco cataract extraction, IOL implantation, goniosynechialysis (GSL) and IZHV, using modest phaco dynamic parameters with intraocular pressure (IOP) set at 30 mmHg through the procedure using Centurion® Vision System equipped with active fluidics while the anterior vitrectomy was set at 4000 or 5000 rpm.
