Objective To describe the surgical technique, visual acuity results, and complications of sutured posterior chamber intraocular lenses with complete pars plana vitrectomy.
Method A retrospective review of 63 eyes was combined with a telephone survey of the patients and their ophthalmologists.
Results The preoperative diagnoses were trauma, 25 eyes; ectopia lentis, 24 eyes; aphakia following retinal detachment surgery, 7 eyes; cataract surgery, 6 eyes; and endophthalmitis, 1 eye. Mean follow-up was 20 months. Preoperative best-corrected visual acuity was 20/40 or better in 36% (23 of 63 eyes), 20/60 to 20/120 in 33% (21 of 63 eyes), and 20/200 or worse in 31% (19 of 63 eyes) improving to 20/40 or better in 76% (48 of 63 eyes), 20/60 to 20/120 in 18% (11 of 63 eyes), and 20/200 or worse in 6% (4 of 63 eyes) at final follow-up. Preoperative complications included iatrogenic retinal breaks in 3 cases, difficulty with a fixation suture in 1 case, and mild vitreous hemorrhage in 1 case. Postoperative complications included retinal detachment in 2 cases, choroidal hemorrhage in 1 case, intermittent pupil capture in 9 cases, self-limiting vitreous hemorrhage in 3 cases, and late intraocular lenses dislocation in 1 case.
Conclusions Suturing a posterior chamber implant concurrently, or following, a complete pars plana vitrectomy is a safe procedure. Complete vitrectomy may reduce the rate of long-term complications. Optimal visual rehabilitation can be achieved without the need for contact lens wear with an acceptable additional risk of surgical complications.
