Visual Outcomes after Phacoemulsification with AcrySof Toric Intraocular Lens Implantation
Introduction: To study the visual outcome of AcrySof toric intraocular lens (IOL) implantation in patients having cataract associated with astigmatism. Materials and Methods: In this prospective interventional case series, 30 eyes of 28 patients with preoperative astigmatism of 1.5–4.5D cylinder underwent phacoemulsification with AcrySof toric IOL implantation. All patients were assessed on day 1, 1 week, 1 month, 2 months, and 3 months postoperatively. The outcome measures were uncorrected visual acuity (UCVA), refractive cylinder, and degree of IOL rotation. Results: Mean UCVA improved significantly in study eyes (P < 0.05) at 3 months. The mean refractive astigmatism reduced from the preoperative value 3.05 ± 0.06 D to 0.208 ± 0.058 D (P=0.001). The mean axis of rotation was 2.76 ± 1.88° in all eyes. Ninety percent of all eyes had mean axis of IOL rotation 10°. Only three eyes had mean axis of rotation 10° or more. Conclusion: AcrySof toric IOL implantation is an effective method to correct preoperative astigmatism in cataract patients.
