Corneal refractive laser surgery has been widely used to correct vision impairment for over 30 years. Three generations of techniques, in particular, have shaped the field of laser vision correction.
Watch the video to experience these major milestones:
PRK, LASIK and SMILE.
With PRK, the visual correction is made directly to the surface of the cornea. Patients experience a difference the same day. However, visual recovery generally takes longer than with other procedures and is frequently accompanied by some discomfort.
LASIK is a widely used laser vision correction procedure, with which excellent results are achieved. Visual recovery is quick and patients generally experience no complications following surgery. A higher incidence of dry eye has been noted in some studies as compared with SMILE.
SMILE is a minimally invasive surgical procedure. Because it requires no flap, the outer corneal layer remains largely intact. As a result, there is less risk of post-surgical complications such as infections or epithelial ingrowth. The overall treatment is gentle and visual recovery is fast.
Small incision lenticule extraction, or SMILE, combines the advantages of PRK and LASIK. With this minimally invasive, flapless procedure, a lenticule is created inside the intact cornea and extracted through a small incision. Because there is no flap, there are no flap-related complications. It thus enables more biomechanical preservation and stability along with less incidence of dry eye. SMILE is redefining refractive surgery as we know it.
