| 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. |
