The use of a per operative qualitative Keratometer is of interest in prevention of astigmatism in cataract extraction. Our study, which included two groups of forty patients each, demonstrated that the Karickhoff Keratometer can markedly decrease the degree of immediate post-operative astigmatism = gain of 2.38 delta in comparison with the control group and astigmatism less than or equal to 2 in 35% of the cases.
