Abstract
PURPOSE: To investigate the complication profile and the long-term functional outcome of combined pars plana vitrectomy and scleral,fixated sutured posterior chamber lens (PC IOL) implantation. DESIGN: Retrospective, consecutive, interventional case series. METHODS: The records of 63 patients (mean age, 67.5 years) were reviewed retrospectively (follow-up, 12 to 132 months; mean, 43.5 months). The under, lying ocular pathologic features; the intraoperative, early (within two weeks after surgery), and late complications (more than two weeks after surgery); final best-corrected visual acuity (BCVA); and the refractive outcome were recorded. RESULTS: Fifty-nine of 63 procedures (93.7%) were performed without complications. Intraoperative complications included vitreous hemorrhage (n = 2), a retinal tear (n = 1), and a rupture of the iris base (n = 1). Early complications included transient raise of intraocular pressure (ICIP; n = 19), transient vitreous hemorrhage (n = 2), scleral tunnel insufficiency (n = 5), pupillary capture of intraocular lens [IOL] (n = 6), persistent vitreous (n = 3), and choroidal hemorrhage (n = 1). Late complications occurred in 12 patients: rhegmatogenous retinal detachment (n = 4), proliferative vitreoretinopathy retinal detachment secondary to the underlying ocular pathologic features (n = 2), choroidal hemorrhage (n = 1), macular pucker (n = 1), and 101, dislocation (n = 4), including two cases of suture break. Mean BCVA in loga,rithm of the minimum angle of resolution units improved significantly from 1.025 (standard deviation [SD], 0.654) to 0.766 (SD, 0.750; P=.03). Mean cylindric equivalent significantly changed from 0.92 diopters (D; SD, 1.075) to 1.76 D (SD, 1.344; P=.005). CONCLUSIONS: The surgical procedures were performed safely in approximately 94% of patients. Most postoperative complications were minor: significant ones occurred in approximately 20%, whereas suture breaks were observed rarely. The only moderate long-term functional improvement in this case series was mainly determined by the underlying ocular pathologic features.
