The purpose of this study was to develop and test prediction algorithms for ALP based on deep learning strategies.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We evaluated a large data set of 1345 biometric measurements from the IOLMaster 700 before and after cataract surgery. The target parameter was the intraocular lens (IOL) equator plane at half the distance between anterior and posterior apex. The relevant input parameters from preoperative biometry were extracted using a principal component analysis. A selection of neural network algorithms was tested using a 5\u2010fold cross\u2010validation procedure to avoid overfitting. The results were then compared with a traditional multilinear regression in terms of root mean squared prediction error (RMSE).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Corneal radius of curvature, axial length, anterior chamber depth, corneal thickness, lens thickness and patient age were identified as effective predictive parameters, whereas pupil size, horizontal corneal diameter and Chang\u2013Waring chord did not enhance the model. From the tested algorithms, the Gaussian prediction regression and the Support Vector Machine algorithms performed best (RMSE\u2009=\u20090.2805 and 0.2731\u2009mm), outperforming the multilinear prediction model (0.3379\u2009mm). The mean absolute prediction error yielded 0.1998, 0.1948 and 0.2415\u2009mm for the respective models.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Modern prediction techniques may have the potential to outperform traditional multilinear regression techniques as they can deal easily with nonlinearities between input and output parameters. However, in all cases a cross\u2010validation is mandatory to avoid overfitting and misinterpretation of the results.<\/jats:p><\/jats:sec>","DOI":"10.1111\/aos.15108","type":"journal-article","created":{"date-parts":[[2022,2,7]],"date-time":"2022-02-07T04:34:16Z","timestamp":1644208456000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Prediction of the axial lens position after cataract surgery using deep learning algorithms and multilinear regression"],"prefix":"10.1111","volume":"100","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-9175-6177","authenticated-orcid":false,"given":"Achim","family":"Langenbucher","sequence":"first","affiliation":[{"name":"Department of Experimental Ophthalmology Saarland University  Homburg\/Saar Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"N\u00f3ra","family":"Szentm\u00e1ry","sequence":"additional","affiliation":[{"name":"Dr. Rolf M.
