Evaluation of in Vivo Glistening Formation in Improved Hydrophobic Acrylic IOLs
Purpose
A recent study demonstrated that the new and improved Acrysof IOLs had decreased glistening density compared to IOLs manufactured in 2003. The goal of this study was to evaluate the glistening density in vivo compared to what was found in vitro.
Methods
49 eyes of 25 patients were implanted Acrysof IOLs manufactured in 2013. Glistening density was measured at 6 months after surgery and compared to the results of the in vitro study.
Results
Glistening was present in all implanted lenses. The mean glistening density found in this study was 38.8 microvacuoles per square millimeter (MV/mm2). It was statistically similar to 39.9 MV/mm2, what have been found in the in vitro study.
Conclusion
The glistening density found at 6 months after surgery was similar to what was found in the in vitro study. It confirms that glistening decreased with the manufacturing process improvements.
