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 ().
A 45-year-old Caucasian male presented with right eye cataract secondary to previous bilateral uveitis in 2008 at the age of 39. Background history includes type 2 diabetes diagnosed in 2011. Ocular history included herpetic keratouveitis with bilateral acute retinal necrosis diagnosed in 2006 (now quiescent) and bilateral relapsing remitting macular oedema treated with multiple IVTA injections. His preoperative right eye vision was counting fingers, and he underwent an uncomplicated phacoemulsification with a 19.0D Alcon SN60WF PCIOL inserted into the bag. Postoperatively, the patient continued to have intermittent severe macular oedema and received three further right eye IVTA injections between 2008 and 2013. His right eye vision has improved to 6/9 by February 2013; however, some right eye PCIOL dislocation was noted. Sixty-four months after his initial PCIOL implant, the patient was found to have right eye in-bag PCIOL dislocation and a vision of 6/24−1 in June 2013. Two months later, he underwent a right-sided anterior approach IOL extraction and secondary anterior chamber IOL implantation. On last review, his right eye vision was 6/36.
