Abstract Details

Purpose:

The objective was to evaluate whether the new hydrophobic acrylic Alcon Clareon SY60WF IOL material shows different or higher silicone oil adhesion properties compared to current commercial available Acrysof SN60WF IOL material.

Setting:

David J. Apple International Laboratory for ocular pathology, Department of Ophthalmology, University of Heidelberg, Germany

Methods:

The IOLs were incubated in NaCl solution (0,9%) for 12 hours and then immersed in silicone oil for 12 hours. Afterwards they were then washed out with distillated water and analyzed and examined under an optical microscope. Coverage of silicone oil evaluation was done using a dedicated image analysis software.

Results:

Silicone oil adhesion on the Acrysof material ranged from 1% up to 17% of both surfaces. Mean value was 9%, the standard deviation was �Â�±4%. The new Clareon hydrophobic material from the same manufacturer had a silicone oil adhesion between 4 and 12%, mean value 8%, standard deviation �Â�±4%.

Conclusions:

In all the studies on earlier generations of the Acrysof materials, silicone oil adhesion was around 33%. This has been reduced now to 8-9% coverage for both IOL materials tested indicating that the new Clareon IOL has a low Silicone Oil interaction and is at least equivalent in its performance to the current biomaterial.
