OBJECTIVE To evaluate the outcomes of three different surgical techniques for foldable posterior chamber intraocular lens (PCIOL) implantation in vitrectomized eyes without capsular support. METHODS A total of 60 patients with aphakic and vitrectomized eyes without capsular support were enrolled. All patients underwent three-piece foldable PCIOL implantation into the posterior chamber through a small corneal incision. Transscleral fixation (TSF), iris fixation (IF), and intrascleral tunnel fixation (ISF) surgical techniques were performed. RESULTS Postoperative PCIOL subluxation or dislocation occurred in one case in the TSF group and two cases in the ISF group. Intraoperative PCIOL dislocation occurred in two patients in the IF group. The incidence of temporary postoperative complications, such as mild intraocular hemorrhage and cystoid macular edema, was higher in the ISF group. No statistically significant difference in PCIOL-related astigmatism was observed between groups. Visual acuity improved in all groups. CONCLUSIONS Postoperative outcomes were comparable between TSF, IF, and ISF for PCIOL in vitrectomized eyes without capsular support.
