BESSt 2.0 WARNING:  Spherical Aberration

  1. We have recently discovered that different Pentacam units display the value of the Anterior Surface Spherical Aberration in different ways (either as an index expressed in e-3 or in microns), depending on whether an engineer has made a special calibration in situ or not). We are working out a conversion factor so that either value can be entered in the future, but for the time being, as the differences can be significant we recommend all BESSt 2.0 formula users (both Myopic and Hyperopic algorithm) to enter 0 (zero) in the Sph Aberr field in order to avoid possible errors in the calculation. When in doubt about the calculated IOL power please compare the results with the old algorithm (BESSt 1.0) and with different formulas if available. Please check this site again in a few weeks for possible updates.


Important note for users of versions prior to 2.0.0.68: the current version is not compatible with databases created with versions before the 2.0.0.68 release. If you want to keep the old database, you will have to Export the database into a csv. file (use the Export function) before installing the new version. Keep this file in a safe place and install the new version. Then open the .csv file, check if the input values are correct and copy all the input values onto the Import.csv file located in the working directory where you have installed the new version. Now from within the program you will be able to import the old database using the Import function.
