Visualization map of authors of studies pertaining to intraocular lens power calculation. Each node in the network represents an author, with larger nodes representing more publications. Different colors refer to clusters of close cooperation; Achim Langenbucher and Giacomo Savini had the greatest number of publications despite belonging to different clusters. Seven clusters were found, each representing a group of researchers who published together in the same area. However, these clusters had limited communication with each other. The network analysis revealed distinctive clusters of authors. 1) The red cluster features Kenneth J Hoffer, Giacomo Savini, and David P Pinero. 2) In the dark orange cluster are Achim Langenbucher, Oliver Findl, Peter Hoffman, and Nora Szentmary. 3) The light orange cluster includes Graham D Barrett, Jinhai Huang, and Jack X Kane. 4) The green cluster represents Jorge L Alio and David Madrid-costa. 5) The pink cluster includes Jyoti Khadka, Konard Pesudovs, and Vijaya K Gothawal. 6) Within the light blue cluster are Jeff H Pettey, Gregory D Kramer, and David J Apple. 7) Finally, the white cluster includes Brent A Kramer and John P Berdahl
