title: Refractive and Quality of Vision Outcomes with Toric IOL Implantation in Low Astigmatism.
abstract: Purpose.To evaluate the refractive and the quality of vision outcomes of toric IOL implantation in patients with low astigmatism.Design.Prospective study of single-arm.Methods.Patients with corneal astigmatism range from 0,75 D to 1,5 D and cataract that underwent cataract surgery with toric IOL. The measurements were performed preoperatively and 6 weeks after the surgery. Patients were evaluated for visual acuity with and without correction, contrast sensitivity, static and dynamic refraction, and quality of life questionnaire. Pre- and postoperative values were compared and their variations were evaluated for linear correlation.Results.21 eyes of 21 patients. Postoperative mean uncorrected visual acuity was 0.80 ± 0.19, and the best corrected visual acuity was 0.97 ± 0.15.p< 0.001 compared to preoperative values. The average postoperative refractive cylinder was -0.34 ± 0.39. The questionnaire's total value before and after surgery was, respectively, 43.20 ± 15.76 and 79.70 ± 10.11 (p< 0.001). The correlation coefficients between the values of the questionnaire variation and the UCVA, BCVA, and CS variation were, respectively, 0.548 (p= 0.005), 0.508 (p= 0.009), and 0.409 (p= 0.033).Conclusion.Patients with low astigmatism who underwent phacoemulsification with toric IOL implantation experienced significant decrease in refractive astigmatism and improvement in their quality of life.
