Purpose:
In this study, we aimed to evaluate the outcomes of the toric intraocular lens (IOL) and capsular tension ring (CTR) suturing technique in patients with cataract and astigmatism.
Methods:
Group 1 comprised 37 eyes of 36 patients to whom the CTR-toric IOL complex was co-implanted after the CTR was sutured to the toric IOL haptic. Group 2 comprised 35 eyes of 33 patients in whom the toric IOL and CTR were implanted without suturing. Both groups were compared in terms of preoperative and postoperative astigmatism, best-corrected visual acuity (BCVA), uncorrected visual acuity (UCVA), and IOL rotation.
Results:
The mean rotation degree was 0.54° ± 2.29° in group 1 and 4.28° ± 8.84° in group 2 (p = .01). While there was no significant difference between the postoperative residual astigmatism and the estimated residual astigmatism in group 1, the postoperative residual astigmatism was statistically higher than the estimated residual astigmatism in group 2 (p = .47 and 0.000, respectively). The mean postoperative UCVA was 0.02 ± 0.04 (logMAR) in group 1 and 0.08 ± 0.13 (logMAR) in group 2 (p = .01).
Conclusion:
The toric IOL and CTR suturing technique provides excellent rotational stability and astigmatism correction.
