Abstract :

Shift of paradigm of the cataract surgery from a visual rehabilitative procedure to a refraction procedure, presents a constant pressure on the surgeon to achieve pre–set refraction target. This is more so valuable in premium category of IOLs which are now been frequently opted by surgeons as well as the patients. The role of Pre– operative IOL calculation is therefore equally important as the surgery itself. The choice of IOL calculation methods therefore is required to be precise and predictably accurate. The present study compares the Laser Interferometry (IOL master) and ultrasonic Biometry for IOL calculation to establish predictable accuracy of the preceding method in achieving emetropia. In the study conventional ultrasonic biometry could achieve post– operative emetropia in only 1/3^rd of the patients whereas with Optical biometry it was achieved in 2/3^rd of the cases thereby substantiating it as a method of choice for universal employment for IOL calculations.
