Outcomes of Re-fixation after the First Intraocular Lens Scleral Fixation

Purpose: To investigate the outcomes of re-fixation after the first intraocular lens (IOL) scleral fixation. Methods: We retrospectively reviewed the charts of patients who underwent second IOL scleral fixation and vitrectomy for dislocation of IOL after the first IOL scleral fixation. We compared the best-corrected visual acuity (BCVA) and spherical equivalent (SE) after 1 month of the first and second surgery, and noted the complications. Results: We included 21 eyes that underwent second IOL scleral fixation: 13 eyes (61.9%) with IOL exchange and eight (38.1%) with one-haptic fixation. Mean BCVAs (LogMAR) were 0.17 +/- 0.25 and 0.11 +/- 0.23 after the first and second surgery, respectively (p = 0.073); mean SEs were -0.94 +/- 1.69 and -0.58 +/- 1.46 diopters after the first and second surgery, respectively (p = 0.076). Postoperative complications occurred in eight eyes (38.1%), including temporarily increased intraocular pressure and suture knots exposure. However, none of the complications required re-operation. Conclusions: The outcomes of primary and secondary IOL fixation were similar, and there were no serious complications of the second surgery.
