FDA has approved a Zeiss PMA for ReLEx Smile to expand myopia treatment to patients with astigmatism. The approval also provides for a small entry incision to be made, allowing the Smile procedure to be less disruptive to the corneal surface tissue, the company says. The device uses the femtosecond laser VisuMax to create a lenticule inside the cornea and access incision in a single treatment step, it says, adding that incisions are made through microscopic-photodisruptions of tissue, created by ultrashort pulses.
