What is the ZEISS ReLEx SMILE procedure?

“SMILE (Small Incision Lenticule Extraction) is a type of laser vision correction surgery that uses the VisuMax® femtosecond laser to remove a small piece of tissue from the cornea, correcting refractive errors such as myopia (nearsightedness) and astigmatism. The procedure is minimally invasive and does not require the creation of a corneal flap, as is the case with LASIK.”
