Toric Intraocular Lens Implantation in the Correction of Moderate-To-High Corneal Astigmatism in Cataract Patients: Clinical Efficacy and Safety

Background/Aims. To investigate the long-term efficacy and rotational stability of toric intraocular lenses (IOLs) implanted for the correction of moderate-to-high corneal astigmatism. Methods. A total of 57 cataract patients (57 eyes) with regular corneal astigmatism (≥2.57 D) were enrolled in this...

description Background/Aims. To investigate the long-term efficacy and rotational stability of toric intraocular lenses (IOLs) implanted for the correction of moderate-to-high corneal astigmatism. Methods. A total of 57 cataract patients (57 eyes) with regular corneal astigmatism (≥2.57 D) were enrolled in this retrospective cohort study. Phacoemulsification with toric IOL implantation was performed for all patients. The uncorrected visual acuity (UCVA) and best corrected visual acuity (BCVA) were recorded before and one year after surgery, and statistical analysis of preoperative corneal astigmatism, postoperative residual astigmatism, aberrations, IOL rotation, and related factors was performed to evaluate the efficacy, safety, and stability of toric IOLs in correcting moderate-to-high corneal astigmatism. Results. One year after surgery, visual acuity was significantly improved compared with that before surgery (preoperative log MAR 0.87 ± 0.34 vs. postoperative log MAR 0.31 ± 0.26, p<0.001), and the self-reported spectacle independence rate was 68.42%. The total residual astigmatism was 1.18 ± 0.85 D, which was significantly less than the preoperative value (3.41 ± 0.99 D) (p<0.001). The degree of toric IOL rotation was 4.93 ± 3.02°, and 54.39% of patients had a lens rotation of less than 5°. The IOLs of 5.26% (3 eyes) of patients rotated more than 10°, and these patients received glasses instead of undergoing IOL repositioning. Conclusions. Toric IOL implantation provided optimal vision outcomes and low spectacle dependence during a one-year follow-up period. The results from our study show that toric IOL implantation is a safe and effective option for cataract patients with moderate-to-high corneal astigmatism.
