enVista hydrophobic acrylic intraocular lens: glistening free

Abstract

The ubiquity of microvacuolization, or glistenings, in popular hydrophobic acrylic intraocular lens material has impacted its safety and effectiveness. The hydrophobic acrylic enVista intraocular lens is manufactured from material proven glistening-free and incorporates the advantages of a 360° square edge to prevent posterior capsular opacification as well as a pure aspheric design to optimize quality of vision and depth of focus.
