Abstract
Objective
To analyze and compare the accuracy of different intraocular lens power calculation formulas in patients with cataract after radial keratotomy.
Methods
Web of Science, Cochrane Library, EMBASE and PubMed were searched for clinical studies published from the establishment of the database to 10th May 2024. Measurements were taken as percentage of eyes of prediction errors within ±0.5 D and ±1.0 D. A network meta-analysis was utilized to compare the different formulas as a way to identify the most advantageous ones.
Results
Results from 11 studies of 674 eyes after radial keratotomy that used 24 formulas were included. A network meta-analysis indicated that
Conclusions
For cataract patients after radial keratotomy, Barrett true-K History and Barrett true-K Partial History were recommended if the prior medical history were available. Otherwise, no single formula is more advantageous without reference to prior medical history.
