Influence of Different Needle Insertion Positions on the Clinical Efficacy of Suture-Fixated Transscleral IOL Implantation Without Knots

Sponsor: Zhongshan Ophthalmic Center, Sun Yat-sen University

Summary

This is a single-blind, single-center, parallel-group randomized controlled trial with the following objectives: First, researchers aim to compare the clinical efficacy of 2mm and 2.5mm post-limbal needle insertion in sutureless transscleral IOL fixation for patients with congenital ectopia lentis. Second, the goal is to investigate the mean absolute refractive prediction error, IOL tilt and decentration, uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), and corneal endothelial cell count at 3 months postoperatively. Third, it intends to explore the incidence of postoperative complications of the two needle insertion positions in this specific surgical method. Finally, this study aims to provide evidence for ophthalmic clinical practice, explore the optimal needle insertion point, and offer more precise and safe surgical plans for patients requiring sutureless transscleral IOL fixation.
