Purpose: Measurement, calculations, visual assessment, and refractive status after monofocal toric intraocular lens (IOL) implantation were the purpose of this study. Methods: This was a hospital-based interventional prospective study, where 40 eyes were included with astigmatism of more than 2D. They underwent biometric assessment using Lenstar. Toric IOL power calculation was done based on Barrett's Toric calculation method. Preoperative axis marking was done using both bubble marker and direct slit beam to avoid cyclotorsion in sleeping position. On table, axis marking was reassessed. Post phacoemulsification, monofocal Supra Phob Toric IOL was rotated till its marking matches corneal axis marking. Postoperative best-corrected visual acuity was measured at 1 and 3 months. Results: Mean of refractive astigmatism reduced from 3.55 +/- 0.97 preoperatively to 0.81 +/- 0.28 at 1 month and 0.79 +/- 0.27 at 3 months postoperatively. In total, 92.5% had residual astigmatism less than 1D at 3 months postoperatively, while 7.5% eyes had residual astigmatism more than 1D. In total, 72.5% patients had IOL rotation of less than or equal to 5 degrees, 20% patients had it between 6 degrees and 10 degrees and 7.5% eyes had more than 10 degrees at day 7 postoperatively, which required IOL repositioning. Conclusion: Accurate measurement of parameters and proper calculation reduce the postoperative residual astigmatism after toric IOL.
