Elemental analysis of aqueous humor in calcification of hydrophilic acryl intraocular lenses

The purpose of this study is to analyze element of aqueous humor in two patients who developed loss of vision resulting from calcification of hydrophilic acryl intraocular lenses (IOLs). That material was compared to aqueous humor that was taken from five patients who was performed vitrectomy + IOL, for diabetic retinopathy, and aqueous humor of five patients without diabetes who underwent phacoemulsification and implantation of IOL. Concentration of calcium and phosphorous in aqueous humor were measured. There was no significantly difference between three groups. Calcification of hydrophilic acryl intraocular lens is not only occurred change of concentration of calcium and phosphorous. The reason for calcification requires further in vitro experimental study.
