Abstract

We used to measure keratometric readings for IOL calculation as obtained by keratometer (Javal ophthalmometer) and recently computer assisted videokerato graphy (C.V.K.). To compare with accuracy of two different instruments we analyzed 100 eyes using Javal ophthalmometer and 100 eyes using C.V.K. in phacoemulsification procedures. Postoperative two months later, we had conclusion which had no significant difference in predicted refraction between two groups and there are a little tendency in myopic pattern in C.V.K. group. Also we found less dioptric power difference between the two groups in younger age, male, irregular astigmatism and small wound.
