SMILE stands for Small Incision Lenticule Extraction. It is the latest minimally – invasive laser refractive surgery for correcting Myopia and Astigmatism. SMILE is a flapless, bladeless form of keyhole procedure
Lasik requires approximately 20mm opening while SMILE requires only a tiny opening (<4mm) to facilitate removing a lenticule.
Lenticule is removed through the small incision, and the disruption of corneal biomechanics is minimal. Once the lenticule is removed from the corneal stroma, the corneal shape is altered, hence the desired refractive correction is achieved.
