A 57-year-old male patient presented to our clinic with a history of blurred vision in the right eye for 10 days. He had no recent systemic disease or ocular trauma history, but he remembered that blurred vision developed just after straining to lift a heavy object. His medical record showed that he underwent uneventful phacoemulsification with capsular bag implantation of a posterior chamber IOL in the right eye under local anesthesia 11 years ago in our institute. The IOL (model AQ2003V, STAAR® Surgical Co., Monrovia, CA, USA) was a three-piece biconvex lens with a 6.3-mm optic and polyimide haptics, and the overall diameter was 12.5 mm. The haptics had a C-shaped configuration and a flat angulation. Postoperatively, the uncorrected visual acuity (UCVA) was 20/20.\nAt presentation, the visual acuity of right eye was 20/60, and the intraocular pressure (IOP) was 11 mmHg by noncontact tonometer. Best corrected visual acuity (BCVA) was 20/20 (−2.25 Dsph = −1.00 Dcyl Ax 90). On slit-lamp examination, the pupil was distorted, and the IOL optic and a proximal part of a nasal fractured haptic were found in the anterior chamber, with cells 3+. After dilation, both ends of the fractured IOL haptic fragment were found to be aligned close to each other at the margin of the capsulotomy, with most of the haptic loop located in the bag []. Severe capsular fibrosis was also noted. Fundus examination revealed no specific abnormality. The corneal endothelial count was 2075/mm2 by specular microscope.\nTo prevent further complication, an operation was performed. Under retrobulbar anesthesia, the dislocated IOL including attached haptic fragment was removed. During operation, the fractured distal haptic fragment was noted and left in the bag. Then, a three-piece IOL (ZA9003, Tecnis®, Abbott Medical Optics, Santa Ana, IL, USA) was fixed in the ciliary sulcus. The extracted IOL was checked grossly, and the fracture site of the haptic was near the optic–haptic junction [].\nOn postoperative day 1, the UCVA was 20/25 and IOP was 10 mmHg. The IOL was fixed in the sulcus and postoperatively there were no further complications. At the most recent presentation, which was 3 weeks after operation, the UCVA was 20/25 and the IOL was well positioned.
A 49-year-old Caucasian male presented with a dense right-sided cortical cataract in 2007 at the age of 44. HIV infection was diagnosed in 1997. His ocular history included bilateral keratoconus, bilateral uveitis, and multifocal choroiditis, which had been treated with eight intravitreal triamcinolone (IVTA) injections previously and was quiescent at the time of his cataract surgery. His right eye vision was 3/60 preoperatively. He underwent uncomplicated phacoemulsification cataract surgery and implantation of a 15.5D Alcon SN60WF into the bag. Postoperatively, his acuity improved to 6/12. Subsequently, he underwent right eye vitrectomy for long-standing vitritis in 2008. Seventy-five months after his initial PCIOL implant, he represented with visual loss in the right eye due to an in-bag IOL dislocation. He underwent a pars plana vitrectomy and removal of IOL. He was left aphakic and managed with a hard contact lens. On the last review in June 2014, his right eye corrected visual acuity was 6/7.5.
