IULIAN VASILE ANTONIAC, MARIAN BURCEA, RAZVAN DANIEL IONESCU, FLORIAN BALTA IOLíS OPACIFICATION: A COMPLEX ANALYSIS BASED ON THE CLINICAL ASPECTS, BIOMATERIALS USED AND SURFACE CHARACTERIZATION OF EXPLANTED IOLíS IOL opacification is a growing issue reported lately in the speciality literature. <1-5> This article follows a series of retrospective cases regarding hydrophobic IOLs that were explanted from three different patients. The explants were examined using AFM and SEM (with EDS), in order to find more details about the surface morphology and the composition of the deposits. The results indicate that they are composed mainly of calcium and phosphate. The authors suggest that ocular comorbidity and other systemic factors are contributing to this complication.
