Abstract: This study helps us to plan the surgery in a way which provides the patient with a spectacle free cataract surgery. The pre-operative K readings of all patients were taken and tabulated age and gender wise. Patients were classified as having WTR and ATR astigmatism. At the end of the study, 98.4 % patients (492/500) showed astigmatism and a mean astigmatism of 1.06+/-0.93 was found in our patients. ATR astigmatism showed a higher prevalence and that too in women. Hence we concluded that evaluating astigmatism pre-operatively is important to plan toroc IOLs or LRIs during surgery to render the patient spectacle free post surgery
