Abstract
[Objective:] To evaluate the clinical efficacy of modified “Z”-shaped knotless transscleral suture fixation intraocular lens (IOL) and traditional knotted transscleral suture fixation IOL in congenital ectopia lentis. [Methods:] A retrospective case study. A total of 73 eyes of 73 patients with congenital ectopia lentis who underwent surgical treatment in our hospital from January 2018 to March 2021 were included. According to different surgical methods, the patients were divided into the knotless group (36 eyes) and knotted group (37 eyes). Preoperative and postoperative of 1-year diopter sphere (DS), diopter cylinder (DC), spherical equivalent (SE), best corrected visual acuity (BCVA), intraocular pressure (IOP), and axial length (AL), corneal endothelial cell counts and the occurrence of postoperative complications rate were analyzed among two groups. [Results:] There was no significant difference in preoperative outcome measures between the two groups (P>0.05). BCVA at 1-year postoperative was significantly better (P<0.05), and SE at 1-year postoperative was significantly lower (P<0.05). There was no significant difference in BCVA, DS, DC, SE, IOP, AL, and corneal endothelial cell loss rate between the two groups at 1-year after operation (P>0.05). One year after the operation, there were 5 cases of suture exposure (13.5%) in the knotted group and no suture exposure in the knotless group, and the difference was statistically significant (P<0.05). [Conclusion:] The modified knotless IOL transscleral suture fixation can improve the best corrected visual acuity and alleviate ametropia of CEL patients, and reduce suture exposure and related complications effectively.
