A 64-year-old Caucasian female presented with right-sided cataract in 2009 at the age of 59. She had a background history of rheumatoid arthritis treated with methotrexate. She had developed right herpetic retinitis in 2005. She underwent uncomplicated phacoemulsification with an Alcon SN60WF inserted in-bag. Loose zonules were noted at the time of the cataract surgery, and no capsular tension ring was inserted. Postoperatively, her acuity was 6/6. In May 2013, 47 months post-surgery review, there was no evidence of IOL instability; however, she represented 6 months later in November 2013 with right eye fluctuating vision and a right-sided in-bag IOL dislocation. Two months later, she underwent a right-sided anterior approach PCIOL explantation and anterior vitrectomy with anterior chamber intraocular lens (ACIOL). Postoperatively, her corrected visual acuity was 6/12.
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.
