About

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).

Enrollment: 75 patients

Sex: All

Ages: 55 to 95 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

Exclusion criteria

• Endothelial cell count less than 1900,
• glaucoma,
• IOP-lowering medications,
• former incisional surgery,
