Theoretically, each person having a refractive defect may undergo corrective surgery, provided they consult their ophthalmologist and there are indications. Each individual decides to undergo corrective surgery for various personal reasons. The intervention is elective. Although it does not promise perfect vision, it keeps its promise of independence from glasses and contact lenses, which allows many people to pursue their hobby, sport or career choices.

A pre-requisite is to have reached 18 years of age and for the refraction to have remained stable over the last year.

Candidates for surgery:

  • People with myopia of up to 10 diopters, hyperopia and astigmatism of up to 6 diopters.
  • Those who for whatever reason do not want to wear glasses or have problems with contact lenses (intolerance)
  • Those who can not wear glasses for careers reasons(aviators, soldiers, firemen, policemen, etc.)
  • Athletes and individuals intensely involved with sports
  • New mothers, who are worried about losing their glasses or unable to monitor their children whilst doing other activities
  • People who travel frequently or spend many hours on the road have advantages such as less dependence on glasses and lenses, greater safety, more comfort.
  • Generally those who care about their appearance


  • Pregnancy. Given that hormones can affect the stability of treatment, pregnant and lactating women are not considered suitable for laser correction.
  • Ophthalmic diseases such as keratoconus, glaucoma, cataract and certain diseases of the retina and optic nerve.
  • Severe dry eye
  • Very thin cornea
  • Viral infections of the cornea, which include the herpes simplex and herpes zoster virus.
  • Uncontrolled diabetes, autoimmune diseases or collagen diseases and immunosuppressive medications should not be given. All these hinder the healing of the cornea.
