ABSTRACT
Any kind of ammetropia-myopia, hypermetropia or astigmatism present after the surgery gives rise to doubts in the mind of patient. In present age patients desire for a postoperative result that can give them a vision without glasses, not only for near but for distance also. Therefore, our endeavour should be to examine the patient thoroughly before the patient is taken to the operation theater. The surgeon should know the preoperative keratometry and his precataract refractive status. Postoperative astigmatism is annoying to the patient, especially if the astigmatism is more than 2.5 D. Because astigmatism of this order, even when fully corrected, causes blurring of the image, leads to field distortion and produces monoocular diplopia. All these problems cause asthenopia, and the patient remains unsatisfied.
