New: search and filter function added to the IOL database window. Option to hide individual IOL types. Several text label and format changes of the data entry form. New IOLcon.org lens data downloaded May 2023.


Version 5.90 (March 2023)

Complete revision of the data input form for IOL treatments. Import of IOL constants from iolCON.org. New fields for IOL properties and constants of the Barrett IOL calculation formula. New evaluation options, especially for cataract surgeries. Mean K value and IOL prediction error over time grah (quartile box plot). Revision of the double angle control diagrams. Troubleshooting the coma scatter plot. Tested on Windows 11 and Office 2021.

Version 5.42 (March 21st 2017)

Fields for implanted IOL data (SEQ, Sph, Cyl, Axis) where not updated during data entry. This is fixed now. Biometry data (ACD, LT, AL) can be deleted again in case of wrong data entry.

Additional corrections and format changes in the data entry form. Near Add and other field contents have been added as option in table view. A bug which made it impossible to import Schwind Amaris data was fixed. Updated near vision graphs after data entry.


Version 5.40c (February 2017)

The data entry form has been changed for toric IOL. Now SEQ + CYL or SPH + CYL can be entered. The data entry form has been optimized for 125% font size on high resolution monitors. Faster page changes when scrolling through patients. Two new graphs about ACD and Axial length distribution have been added under 'cataract outcomes'. Several minor bug fixes and label changes. Support of Hebrew MS Office versions.

A bug which prevented users from entering or displaying the power of an implanted IOL on the IOL data tab was fixed.


Version 5.40a (January 2017)

During conversion of older data files, eyes filed as IOL-Cataract patients lost their surgery type description and got labelled all as 'IOL-Cataract'. This bug was fixed and the old surgery type classification is maintained. Some minor changes on the IOL tab of the data entry form.
