WASHINGTON — A new wavefront-optimized excimer laser from Carl Zeiss Meditec is showing comparable results to other refractive lasers, and company investigators are “eagerly awaiting” final results from the laser’s clinical trials, said Steven J. Dell, MD.

Dr. Dell is an investigator in a U.S. clinical trial of the MEL-80; he and colleagues are evaluating the results of LASIK using the device in 360 eyes at five U.S. sites. Dr. Dell discussed preliminary results of the trial here at the American Society of Cataract and Refractive Surgery meeting.

Enrolled patients have myopia up to -10 D and -3.8 D of astigmatism, Dr. Dell said. The wavefront-optimized procedure is fast, with ablation taking an average of 3 seconds per diopter of correction, he said.

Early results of the study show that 93% of eyes achieved 20/20 or better for uncorrected visual acuity at 6 months; 63% achieved 20/16 or better UCVA; and 27% achieved 20/12 or better UCVA, Dr. Dell said.

In terms of safety, 6% of eyes lost one line of vision, while 34% gained one line. No patients lost two or more lines of vision, he said.
