The procedure for vision correction has come a long way. The latest technology in use is ReLEx Smile Lasik. The revolutionary procedure of LASIK has a drawback: complications of button hole interfere with the procedure. The solution for those who are unable to go through with LASIK is ReLEx Smile.
LASIK is the acronym for Laser Assisted In Situ Keratomileusis. The procedure is the most popular vision corrective aid used. In Lasik a flap is created by directed incision of the cornea using a beam of laser. The flap is then pushed back and a secondary beam corrects myopia. The flap is then replaced back to its original position. Recovery time is minimized to the duration necessary for the flap edges to heal. Most patients who undergo a LASIK are ready to report to work after 24 hours.
This procedure is a combination of ReLEx (Refractive Lenticule Extraction) and SMILE (Small Incision Lenticular Extraction). The procedure, also known as Smile is an advancement of LASIK without the traditional flap requirement. Instead a miniscule hole on the cornea is made. As the procedure does not involve cutting out a flap, the recovery time is further shortened. The side effects of ReLEX SMILE are temporary dryness and disturbed vision under low light.
Difference between ReLEx Smile and Lasik
* While Lasik requires the creation of a flap, Smile is a flapless procedure.
* There are two lasers used in Lasik, one for flap creation the other for correction. On the other hand, Smile utilizes a single beam of laser for directed creation of a keyhole.
* Smile is effective for those patients with thinner cornea and dry eyes.
* The effectiveness of Smile is far higher than Lasik.
* Complete vision correction in patients with very high prescription is successful only by Smile.
* The success rate of Smile is at 100 percent even in patients with over 500 and 1000 degree myopia unlike Lasik.
* The procedure of Smile is completed within 30 seconds (shorter than Lasik)
* Patients who come back for Smile after failed Lasik find the former more comfortable.
* There is no light blackout in ReLEX Smile. In Lasik procedure, the strong incident beam creates a temporary black out. This situation triggers the patient to panic. During Smile, the aiming beam is visible as it is suction of the eye is far gentler.
* Smile may be reversible while Lasik is permanent.
