Strategies for formula constant optimisation for intraocular lens power calculation.
Langenbucher A, Szentmáry N, Cayless A, Wendelstein J, Hoffmann P. Langenbucher A, et al. PLoS One. 2022 May 5;17(5):e0267352. doi: 10.1371/journal.pone.0267352. eCollection 2022. PLoS One. 2022. PMID: 35511906 Free PMC article.
Optimisation was performed using the Levenberg-Marquardt algorithm (SoSPE and SoAPE) or the interior point method (MPE, SDPE, MEDPE, CLPE) for the SRKT, Hoffer Q, Holladay 1, Haigis, and Castrop formulae. The results were based on a dataset of measurements made on 888 eyes …
