The paper is a statistical retrospective trial that evaluates the prevalence of postoperative complications of the cataract surgery in the IInd Department of Ophthalmology Timisoara. The parameters of interest were the type and the frequency of the postoperative complication encountered after the extracapsular cataract extraction (ECCE) followed by a PMMA intraocular lens (IOL) implantation. The most frequent early postoperative complications were endoepithelial comeal edema (20.8%), inflammatory complications (uveitis) (8.72%), hemorrhagic complications (4.02%), and postoperative rise of IOP (8.05%). Out of late complication, we encountered cystoid macular edema (1.34%), bullous keratopathy (1.34%), IOL malposition (0.67%) and secondary glaucoma (1%).
