Abstract

Purpose: To evaluate residual astigmatism after cataract surgery with implantation of a monofocal toric intraocular lens (IOL). Methods: This prospective, non-comparative study included 42 eyes of 42 patients who underwent phacoemulsification with Tecnis Toric IOL implantation at Ho Chi Minh City Eye Hospital between January and December 2024. Uncorrected visual acuity (UCVA), best-corrected visual acuity (BCVA), residual astigmatism, and IOL rotation were assessed preoperatively and at 1 week, 1 month, and 3 months postoperatively. Data were analyzed using SPSS version 26.0. Results: The mean preoperative corneal astigmatism was 1.79 ± 0.35 D. Mean UCVA improved from 0.97 logMAR preoperatively to 0.13 logMAR at 3 months, while mean BCVA improved from 0.59 to 0.019 logMAR (p < 0.001). Residual astigmatism decreased significantly from 1.78 D to 0.28 D at 3 months (p < 0.001). At 3 months, 76.2% of eyes had residual astigmatism <0.5 D and 100% ≤1.0 D. Mean IOL rotation was 1.31° at 1 week, 0.45° at 1 month, and 0.28° at 3 months; 92.9% of eyes demonstrated ≤5° rotation, and none exceeded 10°. Residual astigmatism was strongly correlated with IOL rotation (p < 0.001). Conclusions: Monofocal toric IOL implantation during cataract surgery significantly improved visual acuity, reduced residual astigmatism, and provided excellent rotational stability. This technique is safe, effective, and clinically applicable for managing cataract patients with corneal astigmatism.
