Repositioning of In-the-Bag Dislocated Intraocular Lenses. A Randomized Clinical Trial Comparing Two Surgical Methods

Introduction: To evaluate IOL tilt, IOL-induced astigmatism (IIA), refractive change and impact of capsular fibrosis on IOL position after scleral fixation of dislocated IOL using two methods: Ab Externo Scleral Suture Loop Fixation (Group A) and a modification, Embracing the Continuous Curvilinear Capsulorhexis (Group B). Methods: In this prospective randomized clinical trial conducted at St. Erik Eye Hospital, 117 patients with dislocated IOL were randomized to Group A (n = 61) or B (n = 56). Patients with ordinary pseudophakia (n = 60) served as controls. IOL tilt was measured three-dimensionally with anterior segment optical coherence tomography (AS-OCT). Results: The median IOL tilt was similar with both methods (A: 7.8 °; B: 8.3°; p=0.51), but higher than in ordinary pseudophakia (5.4°; p
