Tools for Reverse Engineering Multifocal Intraocular Lenses

Repository of the project Reverse Engineering of Multifocal Intraocular Lenses Using a Confocal Microscope at TH Köln University of Applied Sciences.

An overview of the processing, measurements and results are featured in:

Mendroch, D., Altmeyer, S. & Oberheide, U.; Characterization of diffractive bifocal intraocular lenses. Sci Rep 13, 908 (2023). https://doi.org/10.1038/s41598-023-27521-7

The same processing has been applied to EDoF (Extended-Depth-of-Focus) intraocular lenses in the following publication:

Mendroch, D., Oberheide, U., Altmeyer, S.; Functional Design Analysis of Two Current Extended-Depth-of-Focus Intraocular Lenses. Trans. Vis. Sci. Tech. 2024;13(8):33. https://doi.org/10.1167/tvst.13.8.33.

The project includes functions from the musurf-reader repository.

Required packages:

matplotlib, numpy, scipy

Tested with Python 3.10

Usage

Measurement files from a nanofocus µsurf custom confocal microscope are required (smt and smi format). A sample measurement can be found under Measurements\.
