Study Overview
Brief Summary
This is an Observational randomized parallel group trial to study and compare the clinical outcomes of Computer assisted and Smartphone based target axis marking for the implantation of a toric intra ocular lens during cataract surgery for patients with regular corneal astigmatism of more than 1.2 DCYL, which will be conducted at Base hospital, Department of Ophthalmology ( teritiary care hospital ) in India. The primary outcome is to measure the final axis deviation of Toric IOL from the calculated axis with the above said methods of axis marking. The secondary outcome is to measure and compare the best corrected visual acuity and postoperative residual astigmatism in both cases.
