"This large cohort study provides encouraging evidence that the 'implant free' Phaco-ELIOS procedure causes minimal trauma, appears to show lasting IOP control with no serious intra- or post-operative complications, and low rate of incisional secondary surgical intervention over a period of at least 8 years," said Thomas W. Samuelson, MD, founding partner of Minnesota Eye Consultants and an Adjunct Professor of Ophthalmology at the University of Minnesota.
