A 79-year-old Korean male with complaints of sudden decrease in visual acuity in the right eye was referred to our clinic. He did not present any remarkable medical history except hypertension. Phacoemulsification with capsular bag implantation of a posterior chamber IOL (AQ2003 V, STAAR Surgical Co., Monrovia, CA) was performed in both his eyes, about 10 years ago in a local clinic. Subsequently, Nd:YAG laser posterior capsulotomy was performed in the right eye at a local clinic. On ocular examination, the uncorrected distance visual acuity (UCVA) was 20/400 for the right eye and 20/20 for the left eye. The best-corrected distance visual acuity (BCVA) was 20/20 (x-10.00 Dsph) for the right eye and 20/20 for the left eye. Intraocular pressure (IOP) was 11 mmHg as measured by noncontact tonometer in the right eye. On slit-lamp examination, the cornea and conjunctiva were unremarkable, and there was no evidence of neovascularization in the iris, while dislocated IOL with intact anterior capsulorrhexis margin was observed in the right eye (Fig. ). We removed the dislocated IOL and fixed a 3-piece IOL (Acrysof MN60AC, Alcon Laboratories, Inc) in the ciliary sulcus under retrobulbar anesthesia. During the dislocated IOL removal operation, a fractured distal haptic was observed (Fig. ), and a proximal haptic was broken when held with a pair of smooth forceps (Fig. ). After the operation, the observed UCVA was 20/20 and the measured IOP was 18 mmHg; the IOL was fixed in the ciliary sulcus. The extracted polyimide haptic was fractured in vitro with 13 shots of 5.5 mJ energy (Fig. ). Patient has provided informed consent for publication of the case
A-76-year old Japanese woman complained of blurred vision in her right eye. She had undergone cataract surgery with an IOL implantation without any complications 12 years earlier. She had also undergone PPV for an ERM and ME in both eyes 8 years earlier. She was diagnosed with sarcoidosis approximately 15 years earlier in another general hospital by a skin biopsy. Oral prednisolone (dose unknown) had been initially prescribed for the vitreous opacities and ME. After the PPV, the uveitis was controlled by topical steroids.\nHer BCVA was 20/25, when she was referred to our hospital in March 2015. The IOP was 13 mmHg and 11 mmHg in the right and left eyes, respectively. Slit-lamp examination revealed no cells in the AC, but a superior subluxation of an in-the-bag IOL was detected (). No pseudoexfoliation or vitreous opacities were present, and pigmented chorioretinal atrophy was found in the peripheary. The foveal ellipsoid zone (EZ) was disrupted in the optical coherent tomographic (OCT) images.\nShe underwent 27-gauge PPV in May 2015. The dislocated 3-piece acrylic IOL was displaced into a pool of PFCL and cut into 3 pieces. The pieces were removed through a 3.5-mm corneal scleral incision. A foldable acrylic IOL (VA-70 AD, HOYA, Tokyo, Japan) was inserted and suture-fixed to the sclera with the ab externo technique as in Case 1. Although the PC-IOL was stable () and the BCVA improved to 20/20 after the surgery, the BCVA decreased to the baseline value at 4 years due to mild macular chorioretinal atrophy. Peripheral pigmented chorioretinal atrophy and mild macular degeneration were clearly observed after the surgery (). A peripheral hypofluorescent lesion was also observed in the fundus autofluorescence images which corresponded with the pigmented lesion ().
