Abstract
Introduction: This prospective study was done to study the rotational stability and efficacy of 3 different toric IOLs to correct corneal astigmatism during phacoemulsification. Materials & Methods: Patients having astigmatism from 1-5 dioptres (D) were enrolled for toric IOL implantation. Toric IOL power was calculated as per toric calculator available online. Calculated power was implanted with axis of the toric IOL as calculated. Residual refractive error and IOL axis was assessed at 1, 4 weeks and 3 months. Results: A total of 52 patients were included in the study. Twenty two patients were implanted with AMO toric IOL, 20 with Alcon toric IOL and 15 with Zeiss toric IOL. Preoperative cylinder ranges from 1-5D in all the three groups. Toric IOL was within 5 degree of its axis in 19 patients in AMO group, 19 in Alcon group and all 15 in Zeiss group. Average refractive cylinder was 0.37D, 42D and 0.31D respectively (p>0.05). Conclusions: Zeiss toric IOL showed better stability among three toric IOLs.
