During LASIK treatment, a very superficial flap will be lifted by an alcohol ‎solution and certain tools and the second laser will then be used. The patient ‎has more pain and needs longer time to achieve perfect vision. However, there ‎is more consistency of cornea and it is more preferable in patients with thin ‎cornea, very high refraction and who are exposed to ocular trauma. ‎


  • Advantages of LASEK and PRK‎
  • Possible complications‎
  • Who are suitable for LASEK surgery and PRK?‎
  • Duration of surgery

‎1- Surgery-induced dry eye is less than femtoLASIK

‎2- Damage to the cornea in this method is less than femtoLASIK

‎3- It has shorter operation time than femtoLASIK‎

‎4- Without any flap-complication due to femtoLASIK‎

‎5- No need for microcratoma or femtosecond laser (so it is more expensive)‎

‎6- Lack of deep inflammation of the cornea

‎7- Suitable for thin corneas and very high refractions

‎1- Foreign body sensation in eyes during 1 to 4 days after surgery‎

‎2- Dry eye and need to eyedrope using
