LASIK
Involve forming a corneal flap with femtosecond laser, it is less painful than the PRK and the visual rehabilitation is faster.
Step 1
Creating the flap
With LASIK a controlled blade is used to create the flap, a hinged piece of corneal tissue. With Femto-LASIK the flap is created with a highly precise femtosecond laser.
Step 2
Relocating the patient
The Patient is conveniently moved from the femtosecond laser to the excimer laser.
Step 3
Folding back the flap
The flap is gently folded back, exposing the inner corneal tissue to be treated.
Step 4
Correcting the error
An excimer laser reshapes the corneal tissue, correcting the refractive error.
Step 5
Repositioning the flap
The flap is returned to its original position, protecting the eye like a natural bandage.

LASIK surgery is a very safe and successful procedure, with 97% of patients achieving 20/40 vision (driving performance). Minority of patients (3/1000) might lose 2 or more lines of vision due to flap complications. Ectasia (gradual bulging of the cornea) is a serious complication, however, the incidence is very low (almost 1/10000) especially with the employment of the advanced diagnostic tools in detecting patient with weak corneas.
Under correction or significant regression of myopia (short-sightedness) could be encountered in 5% of patients, which might need further refractive surgery.

LASIK is recommended for patients age 21 years and above
