Sample item

Which condition is a contraindication to LASIK?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

A. Keratoconus or thin cornea

LASIK weakens the cornea by cutting a flap and ablating stromal tissue, so ectasia risk is high in keratoconus or inadequate residual bed. Other contraindications include severe dry eye and unstable refraction.

Option by option

  • A. Keratoconus or thin cornea (correct)

    Correct. Corneal ectasia risk makes these contraindications.

  • B. Stable refraction for 2 years

    Refractive stability is a requirement.

  • C. Age above 21 years

    Adults over 21 are suitable candidates.

  • D. Myopia of 3 D

    Moderate myopia is a good indication.
