With a highly differentiated femtosecond laser, it is possible to penetrate the corneal surface of the eye which will allow direct laser irradiation to the corneal stroma. Therefore, surgery can be performed in just a few minutes, with a minimal incision thus preserving the front corneal tissue structure, without creating a large corneal flap.
If the laser energy level is high, gas bubbles will be formed in the cornea, thereby resulting in a roughened corneal cut surface. Smile uses low-level energy which is about 600 times lower than that of ordinary LASIK to generate a smoothly cut corneal surface, thereby resulting in quick restoration and higher quality of vision.
There is almost no redness and pain in the eyes on the day of surgery and you can resume your normal daily activities from the next day of surgery since the corneal epithelium is not removed.
