Abstract Details

Purpose:

To compare histological analyses of capsulotomies from four different femtolaser Systems.

Setting:

Dept. of Ophthalmology, University of Heidelberg, Germany

Methods:

Anterior lens capsulotomy disks from four different laser systems were analysed using light microscopy (LM) and transmission electron microscopy (TEM) to examine cellular and stromal changes. Demarcation line was measured and compared statistically.

Results:

All capsulotomies revealed a circular demarcation zone of different sizes. Differences between the laser systems and energy settings correlated with damaged tissue zones.

Conclusions:

Less energy and larger spot separation led to reduced tissue damage. Aberrant laser spots may result in weakening of remaining tissue enhancing the risk for capsular ruptures during surgery.
