Purpose: The objective was to determine in an vitro study optical purity of the Intraocular Lens (IOL) material of the Alcon Clareon SY60WF and comparative IOLs (AMO Tecnis PCB00, Bausch&Lomb Envista and Hoya Vivinex XC1) regarding the development of glistenings.

Methods: The lenses were immersed in a NaCl solution (0.9%) and incubated at 45° for 24 hours in an oven. Afterwards the temperature was reduced to 37° using a water bath. The lenses were stored at 37° for 2.5 hours. After that the lenses were analyzed under a microscope and a dedicated image analysis software was used to count and evaluate glistening formation in the lens material.

Results: Glistenings formation was quantified in numbers of microvacuoles/mm2 (MV/ mm2). The glistening formation in the lenses were for the Bausch&Lomb Envista 1.5±0.9 MV/ mm2, AMO Tecnis 4.47±5.92 MV/ mm2 and Hoya Vivinex XC1 6.07±16.72 MV/ mm2.

Conclusions: On the so called Miyata scale for clinical glistening grading all lenses were on scale of zero, meaning less than 25 MV/ mm2 . The Clareon SY60WF material can be considered as a glistening free as the Envista IOL from Bausch&Lomb.
