Long-term outcome of combined vitrectomy and transscleral suture fixation of posterior chamber intraocular lenses in the management of posteriorly dislocated lenses

摘要

Background: There is no general consensus on the optimal choice of intraocular lenses (IOLs) or fixation methods in eyes with inadequate capsular support. The purpose of this study was to determine the long-term safety, efficacy and refractive status of combined vitrectomy and transscleral suture fixation of posterior chamber (PC) IOLs in the management of posteriorly dislocated lenses in Taiwan. Methods: We conducted a retrospective interventional study at our medical facility. The posteriorly dislocated crystalline lenses (or dislocated IOL) were removed with pars plana vitrectomy followed by transscleral suture fixation of PC IOLs at the same setting. Additionally, preexisting ocular condition, postoperative visual acuity (VA) and refraction were recorded. Results: Fifteen patients were enrolled for analysis, including traumatic posteriorly dislocated IOLs in seven cases, and traumatic posteriorly dislocated crystalline lenses or retained lens nuclei after cataract surgery in eight cases. The end result of our study showed that best-corrected VA of 6/12 or better was achieved in 13 patients (87%) after a mean 45?months follow-up. The mean VA significantly improved from 0.98 logarithm of the minimum angle of resolution (logMAR) at baseline to 0.14 logMAR at last follow-up (p?
