NCT01480557

Brief Summary

Objective of this study is the comparative assessment of the impact of torsional and liquefaction technologies on endothelial cells (ECC), corneal edema (CCT) and corneal sensitivity (CCS) in a sample of cataract patients. Participants were recruited from the Cataract Service of the UHA in a consecutive-if-eligible basis. Eligibility criteria included diagnosis of senile cataract with stage 2 nuclear opalescence according to the Lens Opacities Classification System III (LOCS-3) grading scale \[10\]. By means of a custom computer randomization program all participants randomly populated two study groups according to the cataract-extraction technology used: a) Torsional group (TG) and b) Liquefaction group (LG).
