Abstract (EN): Background: The main options for intraocular lens (IOL) placement without capsular bag support and/or zonular weakness are iris-fixated IOL and scleral-fixated IOL (SFIOL). Purpose: To describe the surgical technique and the outcomes of intrascleral knotless zigzag suture fixation of Akreos AO60 foldable IOL. Methods: Retrospective cohort study of consecutive cases. Results: Ninety-nine eyes of 92 patients were retrospectively studied. The mean age was 72.1 +/- 15.2 years (range 18-94), and the median follow-up duration was 19.5 months (range 3-81). The best-corrected visual acuity improved from a mean +/- SD of 1.34 +/- 0.70 logarithm of the minimum angle of resolution (logMAR) units at baseline to 0.49 +/- 0.56 logMAR at the end of follow-up (p<0.001). The mean +/- SD final SE was -1.24 +/- 1.82 diopters. The mean +/- SD prediction error was -0.51 +/- 1.16 diopters. The overall perioperative complications rate was 44.4% (n=44). The rate of complications requiring invasive treatment was 19.2% (n=19). The most common perioperative complications were ocular hypertension (OHT, 20.2%, n=20), and cystoid macular edema (CME, 15.2%, n=15). The rate of IOL dislocation was 7% (n=7). Conclusion: This knotless technique avoids the risks of haptics fixation but is more prone to IOL dislocation in cases of suture deterioration. Past ophthalmic history needs to be carefully considered in candidates who underwent SFIOL implantation.
