Surgically induced astigmatism (SIA) ranks as one of the principle factors resulting in compromised post- operative visual acuity. There are several factors contributing to the post -operative SIA, namely type and site of wound construction, the age of the patient and the surgical expertise of the surgeon. The first and foremost step in this process is for the surgeon to be aware of the magnitude and the vector of the SIA induced by his/her hands. The SIA online calculator software for orthogonal astigmatism has opened newer vistas in the field of cataract surgery. This software has been developed by Dr Warren Hill and can be downloaded from the online site. To simplify matters, the same data is made available in the form of a mobile APP- the SIA calculator App. This is a rapid and comfortable way to obtain the results.
