Purpose: To provide refractive stability and increase visual performance with the use of a capsular tension ring in trifocal intraocular lens implantation. Methods: This prospective randomized study was conducted in the Yeniyüzyıl university ophthalmology department between February 2018 and September 2019. Eighty-six eyes of 43 patients with visual loss due to uncomplicated cataract in both eyes were randomly divided into two groups, A and B. The eyes in both groups underwent refractive lens exchange with implantation of the same design of trifocal IOL (plate haptic design). In group B, a capsular tension ring was inserted into the capsular bag before trifocal IOL implantation. Both groups were examined at 1 day, 1 week, 1 month, and 3 months postoperatively. At 3 months after surgery, visual acuity, refractive errors and refractive prediction errors were analyzed and compared between groups A and B. Results: The postoperative values in group A were spherical equivalent (mean ± SD), 0.07 ± 0.79 diopters (D); refractive sphere (mean ± SD), 0.43 ± 0.84 diopters (D); uncorrected distance acuity, 0.20 ± 0.04 (logMAR); best-corrected distance acuity, 0 ± 0.02 (logMAR). Group B values were 0.14 ± 0.5 diopters (D), 0.61 ± 0.45 diopters (D), 0.25 ± 0.20 (logMAR), 0.01 ± 0.04 (logMAR), respectively. There was no significant difference between the two groups with respect to the postoperative evaluation. Conclusion: The use of CTR in the implantation of the trifocal intraocular lens had no statistically significant impact on refractive stability.
