Key Points

The aim is to quantify the mechanical stress on the capsular-zonular complex during intraocular lens implantation and compare it between different devices.
Used image-based analysis to measure stress during implantation.
Compared a novel capsular tension ring device with standard intraocular lenses.
Quantitative data on force transmission patterns were recorded.
Significant differences in mechanical stress were observed between the capsular tension ring and standard IOLs.

Abstract

Purpose: To quantify implantation-induced mechanical stress on the capsular–zonular complex using image-based analysis and to compare force transmission patterns between a novel capsular tension ring–based device (fixOflex) and standard intraocular lenses (IOLs).
