Innovative approach to IOL-bag complex fixation with Siepser's scleral sliding knots in pseudoexfoliation syndrome

To assess the 1-month outcomes of visual performance and positional stability of capsule-fixated intraocular lenses (IOLs) in patients with IOL-Bag complex dislocation. We enrolled 36 eyes (34 patients) with IOL-Bag complex dislocation due to pseudoexfoliation syndrome. Patients with intraoperative complications or prior posterior capsule Nd-YAG laser were excluded. Surgical intervention involved creating a superior service keratotomy and using introflective sutures for IOL fixation. Best Corrected Visual acuity (BCVA), endothelial cell counts, and tonometry were assessed at multiple postoperative time points. We also evaluated the mean spherical equivalent (SE), and the residual cylinder and sphere at each follow-up. This study has been successfully registered on ClinicalTrials.gov public (Identifier NCT06423079). The study included 36 eyes, with 22 having a one-piece IOL, 2 with a one-piece IOL plus capsular tension ring, and 12 with a three-piece IOL. Our technique demonstrates a statistically significant improvement in BCVA 1 year after surgery compared to BCVA at the time of IOL dislocation (preoperative BCVA 1.45 ± 0.81 vs 1 year 0.06 ± 0.09 logMAR; p < 0.001). There were no statistically significant differences when comparing the BCVA before the IOL dislocation with the 1-year post-operative BCVA (p > 0.13). No intraocular pressure fluctuations (preoperative IOP 15.0 ± 2.43 vs 1 year IOP 14.69 ± 2.27 p > 0.3), changes in endothelial cell counts (CC) (Preoperative CC: 1812 ± 461 cell/mm² vs 1 year 1760 ± 329 cell/mm²; p > 0.3), or significant complications were observed. This novel surgical technique may represent a viable, economic, and durable solution to restore dislocations of IOLs accessible from the anterior chamber that respect the cornea and restores visual function without damaging ocular structures.
