Short answer
Keratoconus is managed with cross-linking (CXL) to halt progression, specialist RGP or scleral contact lenses for functional vision, and toric ICL when stable 12+ months after CXL. LASIK, SMILE, and PRK are contraindicated. Advanced KC may need corneal transplant — a last resort when lenses and ICL cannot restore usable vision.
Keratoconus treatment options compared
| Option | Purpose | When used | Notes |
|---|---|---|---|
| Glasses | Partial correction | Early / mild KC | Limited for irregular astigmatism |
| RGP / scleral lenses | Functional vision | Moderate KC | Often best non-surgical vision |
| Corneal cross-linking (CXL) | Halt progression | Active / progressing KC | First-line when progression confirmed |
| Toric ICL | Prescription correction | Stable 12+ months post-CXL | No corneal tissue removed |
| LASIK / SMILE / PRK | — | Contraindicated | Ectasia risk — not appropriate |
| Corneal transplant | Restore corneal clarity | Advanced KC only | Last resort when lenses fail |
Treatment by KC stage
- 1Early / suspect: monitor with serial topography; stop eye rubbing; CXL if progression.
- 2Moderate: CXL + scleral or RGP lenses for daily vision.
- 3Stable post-CXL: toric ICL for lens-free correction where irregularity allows.
- 4Advanced: specialist lenses; transplant if corneal scarring limits function.
Why cross-linking comes before ICL
ICL corrects prescription but does not stabilise a progressing cornea. Operating on active KC risks poor outcomes — CXL first, then ICL planning once maps are stable for 12+ months.

Eye rubbing and progression
Vigorous eye rubbing accelerates KC progression. Treat allergy itch with antihistamines and lubricating drops — never rub.
