Compare RatesLASIK for Keratoconus: Candidacy & Cost
Standard LASIK isn't recommended if you have keratoconus. Here's why, what ophthalmologists actually recommend instead, and what those alternatives cost.
Reviewed by Conner, Co-Founder & Research Lead
The short answer
Can you get LASIK with keratoconus?
Almost never with standard LASIK. Keratoconus progressively thins and irregularly shapes the cornea, and LASIK works by removing a layer of corneal tissue to reshape it — on a cornea that's already thin and unstable, that can accelerate the condition instead of correcting your vision. Comprehensive corneal topography during your pre-op screening is exactly how surgeons catch this, which is why keratoconus is one of the standard reasons a LASIK consultation ends in "not a candidate" rather than a quote.
| Procedure | Keratoconus suitability | Typical cost |
|---|---|---|
| LASIK | Not recommended for active or progressive keratoconus | $4,000-$6,000 (both eyes) — reference only |
| Corneal cross-linking (CXL) | Standard first step — halts progression, doesn't correct vision | $2,000-$4,000 per eye |
| PRK (post-stabilization) | Sometimes viable once keratoconus is stable, often combined with CXL | $3,500-$5,500 (both eyes) |
| ICL | Option for residual refractive error after stabilization | $8,000-$14,000 (both eyes) |
CXL is priced per eye rather than as a both-eyes package like the other rows — don't compare it directly to the LASIK/PRK/ICL figures without adjusting for that.
Why LASIK is ruled out
Thin, irregular corneas and tissue removal don't mix
LASIK's reshaping works by removing corneal tissue under a flap. A keratoconus cornea is already thinner and more irregular than a healthy one, so removing more tissue raises the risk of corneal ectasia — the same weakening process keratoconus itself causes, made worse. This is a safety screen, not a judgment call your surgeon can waive.
What ophthalmologists recommend instead
Stabilize first, then reassess
Corneal cross-linking (CXL) is the standard first step — it strengthens the cornea's collagen fibers to stop progression, though it doesn't correct your existing vision. Once a corneal specialist confirms your cornea is stable, PRK, ICL, or Intacs corneal ring segments become real options depending on your case.
Cost framing
What does treating keratoconus actually cost?
The honest answer isn't a single LASIK-style quote — it's usually a sequence. Cross-linking to halt progression runs $2,000-$4,000 per eye and is often the only step needed if caught early enough that vision hasn't degraded much. If refractive correction is still needed after your cornea stabilizes, PRK ($3,500-$5,500 both eyes) or ICL ($8,000-$14,000 both eyes) are added on top, not instead of CXL.
Unlike elective LASIK, cross-linking is sometimes partially covered by vision or medical insurance when documented as medically necessary rather than cosmetic — worth confirming with your specific plan before assuming it's 100% out of pocket the way LASIK typically is.
Before your consultation
Questions to ask a corneal specialist
- Is my keratoconus stable or still progressing? This determines whether cross-linking is urgent or whether other options are already on the table.
- Am I seeing a corneal specialist, not just a general LASIK surgeon? Keratoconus management is a subspecialty — confirm your provider actually treats it regularly.
- Does cross-linking alone fix my vision, or will I need PRK or ICL afterward too? Ask for the realistic full sequence and total cost, not just the next step.
- Will my insurance treat this as medically necessary? Get this in writing before you commit to a treatment plan.
Can I get LASIK if I have keratoconus?
Generally no — the tissue removal LASIK requires can worsen an already-thin, irregular cornea.
Does LASIK work for keratoconus?
No. LASIK corrects refractive error in a healthy, stable cornea; it doesn't treat the condition itself.
What actually treats keratoconus?
Corneal cross-linking first, then PRK, ICL, or Intacs once your cornea is stable — see the full procedure comparison.
How do I get a real candidacy answer?
Only a corneal specialist with topography mapping can confirm it — this page is planning information, not a diagnosis.
