Combined 30-degree bevel up and down technique against 0-degree phaco tip for phacoemulsification surgery of hard cataracts
PURPOSE To evaluate the effective phaco time (EPT), cumulative dissipated energy (CDE) and nucleus emulsification time (NET) as phaco parameters with 0- and 30-degree phaco tip. PATIENTS AND METHODS This prospective, interventional and observational case series included 294 patients scheduled for cataract removal by phacoemulsification technique. Patients with nuclear cataracts of grade 4 and...
متن کاملCorneal endothelial cell loss during phacoemulsification: bevel-up versus bevel-down phaco tip.
PURPOSE To compare corneal endothelial cell loss during cataract extraction by phacoemulsification with 2 different phaco-tip positions. SETTING Ophthalmic Research Center and Department of Ophthalmology, Labbafinejad Medical Center, Shahid Beheshti Medical University, Tehran, Iran. DESIGN Randomized clinical trial. METHODS Eyes scheduled for cataract extraction were randomly assigned sto...
متن کاملComparison of 45-degree Kelman and 45-degree balanced phaco tip designs in torsional microcoaxial phacoemulsification.
AIM To compare the intraoperative performance and postoperative outcome after microcoaxial torsional phacoemulsification using either a Kelman or balanced phaco tip. METHODS Cataracts were treated using 2.2 mm microcoaxial torsional phacoemulsification using either a 45-degree mini-flared Kelman(®) or a 45-degree Intrepid(®) Balanced phaco tip. Intraoperative measurements included total ultra...
متن کاملBevel tip position and corneal damage during phacoemulsification.
Bevel tip position and corneal damage during phacoemulsification Recently, Faramarzi et al. reported on bevel-up versus bevel-down phaco tip during phacoemulsification. We disagree with the authors that it was the first study to consider this subject. Other authors have published studies considering the consequences of phaco needle bevel position on corneal endothelial cells during phacoemulsif...
متن کاملCentral corneal thickness changes in bevel-up versus bevel-down phacoemulsification cataract surgery: study protocol for a randomised, triple-blind, parallel group trial
INTRODUCTION Corneal endothelial damage following phacoemulsification is still one of the major concerns of modern day cataract surgery. Although many techniques have been proposed, the risks of posterior capsular rupture and corneal endothelium damage persist. In theory, damage to the corneal endothelium is minimised by delivering the lowest phaco energy only in the direction necessary to emul...
