In this study we aim to assess the long term outcomes and complication rates in patients who have undergone pars plana vitrectomy and implantation of an ACIOL.
Retrospective review of 30 eyes that underwent secondary ACIOL placement following or concurrently with PPV. Data collected include patient demographic information, surgical procedures, and complications. Late complications were defined as occurring 3 months after ACIOL placement. Reoperation causes and rates were recorded.
Subjects included 22 males and 8 females, with a mean age of 65 years (range 24 to 91). Pre-existing eye conditions included history of RD (47%), history of trauma (40%), ERM (40%), glaucoma (27%), diabetic retinopathy (10%), pseudoexfoliation syndrome (10%), corneal disease (10%), macular edema (10%), uveitis (7%), AMD (7%), macular hole (3%), and retinal vein occlusion (3%). Secondary ACIOL implantation was performed due to a dislocated previously placed IOL (63%), complicated cataract extraction (10%), subluxation of crystalline lens (13%), and aphakia following prior retina surgery (13%). Simultaneous PPV with secondary ACIOL implantation occurred in 97% of eyes. Late complications included persistent corneal edema (16%), lens dislocation (11%), macular edema (10%), epiretinal membrane (13%), hyphema (7%), retinal tear (4%), retinal detachment (4%), persistent vitreous hemorrhage (3%), and uveitis (0%). Six patients underwent reoperation after initial surgery for secondary IOL placement: 3 patients for repositioning of the previously placed IOL, 1 patient for a retinal detachment repair, 1 patient for ERM peel, and 1 patient for exchange of a previously placed glaucoma drainage device. All 3 patients that required repositioning of the IOL had a prior history of trauma.
ACIOL placement in the setting of prior or concurrent PPV is associated with a low rate of long term complications due to the IOL. Prior history of trauma may be a risk factor for lens dislocation and reoperation.
