Background: We compared our early experience of visual outcomes, operation time, and complications for two techniques of intrascleral intraocular lens (IOL) fixation: T-fixation and flanged IOL fixation.
Methods: Data from patients who underwent scleral fixation of an IOL between October 2017 and December 2018 were analyzed retrospectively. Intraoperative time for fixation steps, corneal endothelial cell density (ECD) rate reduction, and intraoperative/postoperative complications were compared between T-fixation (Group T, n = 4) and flanged IOL fixation (Group F, n = 6).
Results: Mean patient age was 73.7 ± 13.0 years. Intraoperative time was significantly longer for Group T (27.5 ± 9.7 min) than for Group F (13.0 ± 3.8 min; P=0.03, Mann-Whitney U-test). Intraoperative complications included iris damage from the 30-G needle in 2 eyes in Group F. Postoperative complications included iris capture by the IOL in 1 eye in Group F. No incidents of postoperative retinal detachment or IOL dislocation were identified. The ECD reduction rate did not significantly differ between groups.
Conclusions: Both techniques yielded favorable surgical outcomes. Flanged IOL fixation might be superior because of its shorter intraoperative time but could initially be technically difficult because of the need to perform angled sclerotomy with a 30-G needle to avoid iris injury.
