“I use artificial tears sometimes” is not an adequate dry-eye screening conversation before elective vision correction. Dry-eye disease can already affect the quality of the measurements a surgeon needs. Corneal refractive surgery may also produce or worsen dry-eye symptoms. If you travel to Colombia expecting a single-day green light, you need to know what happens when the ocular surface is not ready.

Symptoms are one clue, not the whole examination

Patients may report burning, grittiness, fluctuating blur, difficulty wearing contacts or discomfort with screens. Some have abnormal findings despite few symptoms. A clinician should assess the lids, tear film and ocular surface, including slit-lamp examination and appropriate staining. Additional tear tests or gland evaluation may be helpful depending on the presentation; not every patient needs every machine. The point is to document the actual findings and whether they affect surgical eligibility.

Screening also needs to distinguish other causes of irritation such as blepharitis, meibomian gland dysfunction, allergy, or contact-lens-related surface problems. A wet-looking eye is not proof of a healthy tear film. Repeating refraction after treating an unstable surface can change the apparent prescription.

Treatment first can be the best refractive-surgery plan

When active dryness or inflammation is found, the surgeon may recommend treatment and reassessment rather than immediate LASIK. Some people will be safer continuing glasses or contacts, and certain patients may be considered for a different procedure after a specialist evaluation. PRK and SMILE are not guarantees against postoperative dryness. The comparative choice depends on examination findings and the surgeon's assessment.

A sensible quote separates the price of diagnostic testing, any ocular-surface treatment, repeat visits and the eventual surgery. A package that silently assumes all this can happen over a long weekend may be a poor fit for someone with persistent symptoms.

Five things to get in writing

  • Which tests found dryness or eyelid disease, and what were their results?
  • Is treatment recommended before repeat corneal measurement?
  • What improvement would make surgery acceptable, and who judges that?
  • How will postoperative drops or follow-up be managed at home?
  • If surgery is ruled out, which examination costs or deposits remain payable?

Ask for the examination report, not just an emoji-filled WhatsApp assurance. The ESCRS guidance calls for evaluating the tear film and ocular surface in candidates for refractive surgery. The important decision is not whether a clinic offers LASIK; it is whether your eye is ready for it.
