AIMS A total of 97 triple procedures performed over a 6 year period were studied retrospectively to determine the best approach to calculate intraocular lens power. METHODS The cases were divided into two diagnostic categories. RESULTS After 1 year best corrected visual acuity was 20/40 or better in 37.5% of the cases of the ‘modified group’. This group consists of patients with the diagnosis Fuchs’ dystrophy, non-guttate endothelial dystrophy, and Reis–Buckler dystrophy. Analysis of visual acuity was made using logMAR. A final postoperative refraction within 2 dioptres of predicted refraction was achieved in 76.5% of patients in the modified group. CONCLUSION In future, in the absence of a keratometry, a keratometry value of 7.49 mm will be used for calculation of the power of the implant as analysed in this study.
