U.S. trials of Light Adjustable Lens to begin in ’04, surgeon says
NEW YORK U.S. trials of the Light Adjustable Lens will begin in 2004, according to the lens developer.
Daniel M. Schwartz, MD, said that the lens, manufactured by Calhoun Vision, has a 4 D range of adjustment and will be able to correct myopic, hyperopic and astigmatic errors.
In vitro and animal studies demonstrated the ability to perform precise adjustment of myopic and hyperopic errors, with no leaching of macromers, Dr. Schwartz said. In human trials conducted in four eyes, the lenses were well tolerated and biocompatible at 6-month follow-up. Dr. Schwartz said adjustment is easy for both doctor and patient.
