Calcification in Hydrophilic Intraocular Lenses Associated With Injection of Intraocular Gas

The areas of opacification in all 3 hydrophilic IOLs were attributable to calcification. We postulate that intraocular gas use and the altered blood-aqueous barrier of these complicated traumatized eyes co-act to trigger secondary IOL calcification. Further experimental testing is needed to confirm this clinical association.
