Astigmatism Correction in Cataract Surgery with Foldable Toric IOL

Abstract

<p><strong>Aim:</strong> To evaluate correction of pre-existing astigmatism after foldable Toric IOL implantation in patients undergoing cataract surgery.</p><p><strong>Materal & Methods:</strong> In this prospective observational study we included 10 eyes of 10 patients with astigmatism between 2.00D to 6.00D &undergoing cataract surgery. Phacoemulsification was performed with Toric IOL implantation through 2.8mm clear corneal temporal incision. Patients were examined post operatively for Uncorrected Visual Acuity (UCVA), Best Corrected Visual Acuity (BCVA) & residual refractive astigmatism.</p><p><strong>Statistical Analysis:</strong> Statistical analysis was performed by the SPSS program for Windows, ver.16.0.Continuous variables are expressed as mean ± SD, and categorical variables are presented as absolute numbers and percentage. For the statistical test, a p value less than 0.05 was taken to indicate a significant difference.</p><p><strong>Results:</strong> The UCVA was 6/9 or better in 90% of eyes. 80% eyes achieved 6/6 BCVA. The mean refractive cylinder corrected from -3.4 ± 1.4 D to -0.60 ± 0.27 D which was statistically significant. (p value=0.0001).</p><p><strong>Conclusion:</strong> Toric IOL implantation is an effective, safe surgical option to manage pre-existing corneal astigmatism during cataract surgery.</p>
