We evaluated the state of aftercataract in 90 eyes 3 years after uneventful phacoemulsification-aspiration with intraocular lens implantation. The age of patients averaged 70.3 years. A color map analysis was used to quantitate the density of aftercataract after the diaphanoscopic image was photographed by an anterior segment image analyzer (EAS1000®). Based on slit-lamp photographs, the aftercataract was classified into 2 clinical types, fibrous proliferation and Elschnig pearls. The fibrous proliferation type showed numerous low-density areas over 129 cct (computer-compatible tape). The Elschnig pearl type showed numerous high-density areas below 129 cct. In areas between 106 and 128 cct, there was a higher frequency of Elschnig pearl type (p<0.05). Color map analysis promises to be useful in the classification of aftercataract as its findings were correlated with the two clinical types classified by slit-lamp photography.
