Venturi vacuum yields efficiency without increasing risk for capsular breakage
WAIKOLOA, Hawaii – Venturi vacuum is not more likely than peristaltic vacuum to break the capsular bag during phacoemulsification, according to a study presented here.“Venturi vacuum does not increase the risk of capsular breakage with ultrasound,” Randall J. Olson, MD, said at Hawaiian Eye. “[Capsular breakage] comes from tip contact and not occlusion of the overall tip. You need ultrasound. And transversal [ultrasound] is significantly more likely to break the capsule.”
