<br/><br/> This is a prospective comparative non - randomized clinical trial evaluating the efficacy and complications of 2 phacoemulsification surgical techniques: Group A: 20 patients using phaco counter prechopping technique; and Group B: 20 patients using stop and chop technique. Outcome measures are A) Intraoperative phaco (ultrasound) time, cumulative dissipative energy (CDE) and complications; and B) Post-operative changes in corneal endothelial cell loss, cornea thickness and BCVA at 3 months compared to baseline. We experienced difficulty in acquiring the necessary surgical skills for the Counter Prechopping technique with a high intraoperative complications, thus it was necessary to stop at 14 attempted eyes in group A
