TRIPLE PROCEDURE - ANALYSIS OF OUTCOME, REFRACTION, AND INTRAOCULAR-LENS POWER CALCULATION

Aims-A total of 97 triple procedures performed over a 6 year period we re studied retrospectively to determine the best approach to calculate intraocular lens power. Methods-The cases were divided into two diagn ostic categories. Results-After 1 year best corrected visual acuity wa s 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-gu ttate endothelial dystrophy, and Reis-Buckler dystrophy. Analysis of v isual acuity was made using logMAR. A final postoperative refraction w ithin 2 dioptres of predicted refraction was achieved in 76.5% of pati ents in the modified group. Conclusion-In future, in the absence of a keratometry, a keratometry value of 7.49 mm will be used for calculati on of the power of the implant as analysed in this study.
