ReLEx SMILE is a less invasive way to treat short-sightedness and astigmatism. Traditional laser treatment involves creating a flap on the cornea, before using a second laser - the Excimer Laser, to reshape the cornea. With ReLEx SMILE, no corneal flap is required.
A 4mm opening is all ReLEx SMILE needs. This minimally invasive technique allows the surface tissue to remain intact, thus significantly preserving the biomechanical strength of the cornea.
