Abstract Details

Purpose:

The aim of the study was to compare the post-surgical coating of the endothelium with dispersive and cohesive OVD’s after cataract surgery.

Setting:

International Vision Correction and Research Center (IVCRC), University Ophthalmology Hospital Heidelberg, Germany

Methods:

Cataract surgery was performed in a wetlab setting with 10 porkine eyes per group using fluoreszein stained OVD’s. In Group 1 the cohesive OVD Healon® (AMO, USA) was used, for group 2 we used the dispersive OVD Endocoat® (AMO, USA) and in group three we performed a soft-shell technique with the combination of both OVD’s. After phacoemulsification the cornea was trephined and a picture under blue light of the endothelial side taken. The pictures where analysed with the EPCO program and the endothelial coating analysed.

Results:

In group one with the cohesive OVD the lowest endothelial coating could be found. Group two and group three showed a statistically significant higher coating of the endothelium. While the soft-shell group delivered the highest values, there were no statistically significant differences between group 2 and 3.

Conclusions:

Dispersive OVD’s have a higher affinity to the endothelium and so offer a better protection during cataract surgery compared to cohesive OVD’s. The highest adhesion was seen using the soft-shell technique.
