A Case of Acute Angle Closure Caused by Dislocation of Accommodative Intraocular Lens

ABSTRACT

PURPOSE: To report a case of acute angle closure after cataract surgery using an accommodative intraocular lens (IOL), WIOL-CF® (GELMED, Praha, Czech). CASE SUMMARY: A 46-year-old male patient underwent phacoemulsification and implantation of WIOL-CF® into the capsular bag. Seven months after the surgery, a sudden increase in intraocular pressure (IOP) associated with angle closure was observed. Ultrabiomicroscopy revealed a dislocated WIOL-CF® that was pushing the peripheral iris anteriorly. Despite the use of IOP-lowering medication and peripheral laser iridotomy, IOP was not controlled. After the use of cycloplegics, the angle was widened and IOP decreased; however, after nine days, the WIOL-CF® was completely dislocated into the anterior chamber and so was removed. CONCLUSIONS: When performing cataract surgery using WIOL-CF®, a possibility of dislocation of IOL and subsequent angle closure should be considered.
