Abstract Details


To compare the occurence, the number and size of glistenings, when warming and cooling in vitro 9 different hydrophobic acrylic materials


Acrylian Ltd, 22 rue de la Ganzau 67000 Strasbourg, FRANCE; Clinique Juge 108 rue Mermoz 13008 Marseille, FRANCE


Glistening measurement was assessed in vitro by counting microvacuoles with an optical microscope at X100 magnification in different acrylic materials used to produce manufactured intraocular lenses, placed at 45°C in a saline solution during 24 hours, than cooled down to 35° C and examined 6 hours later. ImageJ software was used to determine the diameter of glistenings using a sight with a scale set. Whitening was assessed by analysing hydrophobic acrylic buttons placed in pure water at 35°C over 2000 hours, using pictures taken with a camera and analysed every week with the ImageJ software, with arbitrary units.


Number of microvacuoles varied from 0 to 191/mm²; the diameter of microvacuoles varied from 12 to 54 micromillimiters, depending of the analyzed material . The importance of whitening also varied significantly between the hydrophobic acrylic lenses.


We found significant differences in glistening formation and whitening for 9 hydrophobic acrylic under experimental warming/cooling conditions.
