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-76-year-old Japanese woman complained of blurred vision in her left eye. She reported that she had undergone cataract surgery with an implantation of an IOL without any complications 8 years earlier. She also reported that she had been diagnosed with presumed sarcoidosis 15 years earlier in another University Hospital based on the Japanese diagnostic criteria. Although mild iritis, vitreous opacities, and peripheral multifocal chorioretinitis were present, the iritis was under control by topical steroids. She had undergone pars plana vitrectomy (PPV) with cataract surgery in an eye with mild vitreous opacities, an epiretinal membrane (ERM), and macular edema (ME) in another eye 12 years earlier. Since then, the ocular inflammation has been stable in both eyes.\nWhen she was referred to our hospital, her best-corrected visual acuity (BCVA) was 20/20 in the eye with the inferiorly subluxed IOL in her left eye (). The intraocular pressure (IOP) was 9 mmHg in the right eye and 10 mmHg in the left eye. Slit-lamp examination revealed no cells in the anterior chamber (AC). Pseudoexfoliation was not observed, but multifocal hyperpigmented chorioretinal atrophy was present in both eyes. After an increase of blurred vison to 20/25, she underwent 25-gauge pars plana vitrectomy in January 2011 during which the 3-piece acrylic IOL was displaced into a bed of intravitreal perfluorocarbon liquid (PFCL). The IOL was then removed through a 7.0-mm corneal scleral incision. A constriction of the capsule of the lens was not observed intraoperatively. A fornix-based conjunctival peritomy was made at 270 degrees followed by the construction of a partial thickness triangular limbal based scleral flaps 180 degrees apart. Then, a one-piece P336UV (Bausch and Lomb, Rochester, NY) was placed in the posterior chamber (PC) using the ab externo method with PAIR-PAKTM needles (Alcon Laboratory). Then, 10–0 polypropylene sutures were passed through the haptic eyelets and sutured to the sclera. The suture knots were buried under the scleral flaps, and scleral flaps were sutured with 8–0 vicryl sutures to avoid suture-related complications. Thereafter, the IOL was stable with minimal cells in the AC, and the BCVA has remained between 20/20 to 20/16 for 8 years (). Confluent pigmented chorioretinal atrophy was clearly observed postoperatively (). The visual field was constricted ().
