FDA OKs Carl Zeiss PMA for VisuMax Laser
FDA has approved a Carl Zeiss Meditec PMA for the VisuMax Femtosecond Laser for the small incision lenticule extraction procedure to reduce or eliminate nearsightedness in certain patients 22 years of age or older. The device removes a small amount of eye tissue to permanently reshape the cornea, according to an agency news release. “A femtosecond (very fast, short-pulsed) laser makes cuts within the cornea, creating a disc-shaped piece of tissue that is removed by the surgeon through a small incision in the surface of the cornea,” it says. “This tissue removal causes the shape of the cornea to change, which corrects the nearsightedness.”
Approval was based on data from a 328-patient clinical study that found the procedure resulted in stable vision correction at six months. “Of the 328 participants evaluated at six months, all but one had uncorrected (without glasses or contacts) visual acuity of 20/40 or better, and 88% had uncorrected visual acuity of 20/20 or better,” FDA says.
