LASIK
Lasik or Excimer laser Assisted Kerato- mileusis treatment can be adopted instead of surface treatment when the level of myopia is not very high.
The operation is divided into two parts:
1) An instrument called microkeratome is used to make a superficial flap of the cornea. The flap, an extremely thin layer of the cornea, is mobilized and lifted leaving the underlying part of the cornea uncovered.
2) Laser treatment is applied on the uncovered cornea as in PRK, then the flap is replaced on the underlying cornea.
 An eye-drop anesthetic is used for this non-painful treatment. The patient feels no pain in the postoperative period except for a slight foreign object sensation or slight ocular irritation.
The visual improvement is immediately noted by the patient, although total visual recovery usually requires one week.
LASIK is widely performed worldwide to correct myopia, astigmatism and hyperopia. The advantages of LASIK consist in less patient discomfort and slightly faster recovery.
