Which procedure is used to halt progression of early keratoconus?

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

The answer and the reasoning

B. Corneal collagen cross-linking with riboflavin and UV-A

Cross-linking increases collagen bonding and corneal rigidity and stops ectasia. LASIK and PRK weaken the cornea and are contraindicated in keratoconus.

Option by option

  • A. Radial keratotomy

    Radial keratotomy weakens the cornea and is obsolete.

  • B. Corneal collagen cross-linking with riboflavin and UV-A (correct)

    Correct. It stabilises the cornea.

  • C. Photorefractive keratectomy

    PRK removes tissue and may worsen ectasia.

  • D. LASIK

    LASIK is contraindicated in keratoconus.
