| Summary: | Purpose: To evaluate posterior capsule opacification (PCO) in patients 7 years after cataract operation with the implantation of three types of intraocular lenses (IOL): rigid polymethylmetacrylate IOL (PMMA) with a round optical edge, foldable hydrophobic acrylate IOL with a sharp edged optic and foldable IOL whose optical part is made from silicone with round edges. For the quantification, two computerized methods were used and the correlation of the two systems was evaluated. Data from both methods were used to compare PCO incidence for the followed IOL and ascertain if some type of IOL showed better qualifications in the prevention of posterior capsule opacification. Patients and methods: We evaluated 73 patients that had undergone cataract operation using the classic ultrasound phacoemulsification method in the time period of 1998-2000 at the Ophthalmology Department of the Hradec Kralove Faculty Hospital. Seven years after the operation, a standard ophthalmologic examination was performed including best corrected visual acuity (BCVA) and a digital photograph of the anterior segment of the eye in mydriasis, focusing on the posterior capsule. On the photograph, posterior capsule opacification were evaluated using the Evaluation of Posterior Capsule Opacification 2000 software (EPCO 2000) and the...
