Short answer
No — LASIK cannot fix keratoconus and is absolutely contraindicated. LASIK removes corneal stromal tissue from an already weakened, irregular cornea — this dramatically increases the risk of post-LASIK ectasia (progressive corneal bulging and vision loss). The correct pathway is corneal cross-linking (CXL) to halt progression, then toric ICL when the cornea is stable 12+ months — not corneal laser.
Why is LASIK dangerous for keratoconus?
Keratoconus thins and steepens the cornea. LASIK removes additional tissue — leaving insufficient structural support. Ectasia after LASIK in KC patients can be worse than untreated progression.
Responsible clinics decline LASIK when Pentacam topography shows irregular astigmatism, inferior steepening, or other KC signs — even if vision seems acceptable on a standard eye test. That decline is patient safety, not a dead end.
I was declined for LASIK — do I have keratoconus?
Not always — but topography decline often reveals sub-clinical KC. Many patients discover keratoconus only during pre-LASIK screening. A corneal specialist confirms the diagnosis and plans CXL if progressing.

What is the correct treatment pathway?
- 1Diagnose: Pentacam topography + corneal specialist assessment.
- 2Stabilise: CXL if progression confirmed — halts further bulging.
- 3Functional vision: RGP or scleral lenses while monitoring stability.
- 4When stable 12+ months: Toric ICL for prescription correction without corneal tissue removal.
What about forme fruste keratoconus?
Forme fruste KC — sub-clinical topography changes with good vision — is still a contraindication for LASIK and SMILE. Operating on a borderline cornea risks ectasia even when symptoms are mild.
