Abstract. Purpose:To report the state of refraction following cataract surgery with intraocular lens(IOL)implantation in an eye that had received radial keratotomy before. Case:A 61-year-old female presented with impaired vision in the right eye. She had received radial keratotomy in both eyes for myopia at the age of 30 years. She had received cataract surgery in the left eye 2 years before. Refraction after surgery showed an error by −02.54 diopters after determination of IOL after Haigis-L formula. Findings:Corrected visual acuity was 0.4 right and 0.7 left. Eight radial scars were present in either eye. The right eye received cataract surgery. Axial length was measured by IOL Master® and corneal curvature by Pentacam® True Net Power method. IOL power was calculated after SRK/T formula. Error of refraction from predicted value was 0.25D after IOL Master, −7.2D after ring 3 method, −0.04D after True Net Power method, and −2.49D after Haigis-L formula. Conclusion:Error of refraction from the predicted value was minimum when the power of IOL was calculated after True Net Power and SRK/Y formula.
