Summary: Posterior capsule opacification (PCO) is the late and the most often occurring complication after cataract surgery. Several forms of posterior capsule opacification are distinguished clinically. Mechanism of their formation consists of anterior capsule epithelial cells migration towards posterior capsule, where they proliferate forming opacification. Pre-surgery factors which have an effect on PCO are as follows: type of cataract, patient´s age and accompanying diseases. Intraoperative factors having an effect on PCO reduction are: small incision, atraumatic surgery, wide capsulorhexis, accurate hydrodissection, and cortical masses removal, capsule polishing, intracapsular fixation of the lens. The choice of the suitable lens is also a very important task i.e. acrylic hydrophobic lens with optic part characterized by a big diameter and sharp posterior biconvex of ?one piece lens? with haptic parts without angulation are recommended. PCO can be treated by surgery or laser capsulotomy. In order to reduce PCO formation, experimental studies on prevention methods are carried out by testing the pharmacological preparations which have an influence on inhibition of epithelial cells proliferation or cause their necrosis.
Keywords: cataract surgery, intraocular lens, posterior capsule opacification, capsulotomy.
