[Correlation between prognostically predicted and actually attained refraction].

Abstract:

BACKGROUND:In cataract surgery high quality is demanded. That is why high precision in calculation of IOL power is necessary for predicting postoperative refraction. MATERIALS AND METHODS:In a series of 103 patients the predicted refraction--calculated by the SRK II formula for only one type of IOL (A-constant 118.9)--was compared to the received early and late (3 month) postoperative refraction. RESULTS:The accuracy of IOL calculations in 95% was acceptable--within a range of 2 diopters. The prediction errors of extended values were only shown in cases of axial length of more than 26 millimeters. CONCLUSIONS:The results confirm the fact that by means of SRK II formula the accuracy of IOL calculation is satisfactory in respect of predicted refraction. In eyes of elongated axial length the accuracy is limited.
