RESUMEN
To report the incidence of posterior capsule opacification with different types of intraocular lenses. 72 patients [72 eyes] with senile cataract were divided into 3 groups. Their ages ranged between 65 and 72 years. Group I underwent large incision extracapsular cataract extraction [ECCE] and received all PMMA IOL, group II underwent phacoemulsification and received polyacrylic IOL, and group III underwent phacoemulsification and received silicon IOL. All patients were followed up for 2 years to detect PCO. At 2 years PCO was less significant in patients who had implanted polyacrylic IOL than those with silicon or PMMA [P < 0.001]. The lower incidence of PCO with polyacrylic IOL suggests that the IOL material may reduce the incidence of PCO
