Abstract: The objective of this study was to evaluate the outcome and correction of pre-existing corneal astigmatism after Toric IOL implantation in patients undergoing cataract surgery [4].
Design: Retrospective case study [22]
Material And Method: In this retrospective study, we included 150 eyes of 150 patients; with cataract and regular corneal astigmatism between 1.50 to 3.50 D. Phacoemulsification was performed with Toric IOL implantation through 2.8mm clear corneal temporal incision [4].
Studied parameters before and after surgery included uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA) & residual refractive astigmatism [6].
Results: Preoperatively UCVA was 20/200 or less in 80 eyes (53.33%), 20/125 to 20/80 in 50 eyes (33.33%), 20/63 to 20/40 in 20 eyes (13.33%). Postoperatively UCVA was 20/80 in 12 eyes (8.00%), 20/63 to 20/40 in 103 eyes (68.66%), 20/32 to 20/25 in 35 eyes (23.33%). All eyes had 20/20 BCVA (100%). Preoperatively, 30 eyes have -1.50 to -1.75D. Astigmatism (20%), 50 eyes had -2.00 to -2.50D. Astigmatism (33.33%), 70 eyes had -3.00 to -3.50D. Astigmatism (46.66%). Postoperatively, 90 eyes had -0. 50D. Astigmatism (60%), 40 eyes had -0. 75D. Astigmatism (26.66%) and 20 eyes had -1. 00D. Astigmatism (13.33%) [8].
Conclusion: Toric IOL’s allow correction of astigmatism without compromising the integrity of the cornea. They provide predictable results and can reduce healing times as there is less surgical impact on the cornea. Toric IOL implantation is an effective and safe surgical option to manage pre-existing corneal astigmatism during cataract surgery [4].
