TORIC IOL-CAPSULE TENSION RING SUTURING TECHNIQUE FOR TORIC IOL STABILITY

To examine the results of the toric intraocular lens (IOL) and capsular tension ring (CTR) suturing technique in patients with cataract and astigmatism.

Konyagoz Eye Hospital, Department of Ophthalmology, Konya, Turkey

This is a retrospective observational study. Patients who underwent phacoemulsification and toric IOL implantation due to cataract and astigmatism from June 2020 to July 2021 and whose follow-up was completed in the next six months in our clinic were enrolled. In all patients, the CTR-toric IOL complex was co-implanted after the CTR was sutured to the toric IOL haptic using the toric IOL-CTR suturing technique we described previosly (Ucar F, Ozcimen M. Can toric IOL rotation be minimized? Toric IOL-Capsular Tension Ring suturing technique and its clinical outcomes. Semin Ophthalmol. 2021 Jun 6:1-6. doi: 10.1080/08820538.2021.1933545). Preoperative and postoperative astigmatism, corrected distance visual acuity (CDVA), uncorrected visual acuity (UCVA), and IOL rotation were evaluated.

143 eyes of 152 patients were included in the study. The mean age was 63.9 ± 8.5 months. The mean follow-up time was 13.1 ± 5.3 months. There was no significant difference between the postoperative residual astigmatism and the estimated residual astigmatism (p>0.05). Toric IOL rotation was observed in only 2 eyes and it was 10° in both eyes. The mean rotation degree was 0.2° ± 1.4°. The mean preoperative astigmatism was -3.2 ± 1.2 diopters(D) and the mean postoperative residual astigmatism was -0.3 ± 0.3 D (p <0.001).

The toric IOL and CTR suturing technique serves as a rivet for toric IOLs and provides excellent rotational stability. This leads to excellent postoperative visual outcomes and patient satisfaction.
