[Comparative study of posterior corneal epithelium after different cataract phacoemulsifiication techniques]

Comparative study of posterior corneal epithelium showed that ultrasound torsional phacoemulsification (OZil) at present is the most preserving technique with regard to posterior epithelium damage. Hidromonitoring phacofragmentation has comparable results in grade II nucleus density in terms of posterior epithelial cell loss. Torsional phacoemulsification in patients with grade IV nucleus density is the most effective and preserving low-energy technique of cataract removal.
