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

Purpose: To report a case of acute angle closure after cataract surgery using an accommodative intraocular lens (IOL), WIOL-CF (R) (GELMED, Praha, Czech). Case summary: A 46-year-old male patient underwent phacoemulsification and implantation of WIOL-CF (R) 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 (R) 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 (R) was completely dislocated into the anterior chamber and so was removed. Conclusions: When performing cataract surgery using WIOL-CF (R), a possibility of dislocation of IOL and subsequent angle closure should be considered.
