BACKGROUND The recent years have seen a huge increase in the burden of cataract surgery in India along with a decreased tolerance for spectacles in patients after cataract surgery. These changing trends have made it essential for each surgeon to strive for the ultimate goal of postoperative emmetropia by minimising the Surgically-Induced Astigmatism (SIA). One of the main factors influencing SIA is the type of cataract surgery due to the differences in their incision size. Presently, both Small Incision Cataract Surgery (SICS) and phacoemulsification are widely practised all over our country. Such a scenario makes it relevant to compare the two surgeries and adopt the one with better visual outcome in order to keep up with patient expectations. In our study, we aimed to compare the magnitude of postoperative SIA and Best Corrected Visual Outcome (BCVA) between SICS and phacoemulsification. Moreover, while all phaco surgeries were performed using a superior clear corneal incision, all SICS cases used an incision on the steeper axis. MATERIALS AND METHODS 300 operable cataract patients (
