Abstract

Objective: To evaluate the efficacy of the toric intraocular lens (IOL) and capsular tension ring (CTR) suturing technique in eyes with long axial length (AL) with a high risk of toric IOL rotation.<br />Methods: This is a retrospective observational case series. The data files of patients who underwent a one-piece acrylic toric IOL (Tecnis Toric IOL and Acrysof IQ Toric IOL) implantation with the toric IOL and CTR suturing technique for cataract and astigmatism or toric IOL repositioning were analyzed. Inclusion criteria were a regular total corneal astigmatism of ≥ 1.5 D and an AL of ≥ 26.0 mm. Preoperative and postoperative astigmatism, uncorrected distance visual acuity (UDVA), IOL rotation, intraoperative, and postoperative complications were evaluated.<br />Results: A total of 30 eyes of 29 patients were included in this study. The mean AL was 27.82 ± 1.53 mm (range, 26.08-31.07). UDVA revealed a statistically significant improvement from 0.84 ± 0.20 logMAR preoperatively to 0.04 ± 0.06 logMAR postoperatively (p < 0.001). The mean preoperative corneal astigmatism was 3.08 ± 1.01 D reduced to the postoperative residual astigmatism of 0.59 ± 0.32 D which was found also statistically significant (p < 0.001). Only 2 eyes (6.2%) had postoperative toric IOL rotation of 5° and 10°, respectively. The mean degree of postoperative rotation was 0.50 ± 2.01.<br />Conclusion: This technique provided excellent rotational stability even in eyes with longer AL and did not require additional intervention.<br /> (© 2023.
