Ortho-K vs LASIK
LASIK reshapes your cornea permanently. Ortho-K reshapes it overnight, temporarily, for as long as you keep wearing the lenses.
Both get you through the day without glasses. Everything that differs between them follows from that one distinction.
The core difference
LASIK uses a laser to remove corneal tissue and change its curve. One procedure, and the result is permanent — because the tissue is gone and does not grow back.
Ortho-K uses a rigid, highly oxygen-permeable lens worn while you sleep. It redistributes the outermost layer of corneal cells — the epithelium, which renews itself continuously — to flatten the centre of the cornea. You take the lens out in the morning and see clearly through the day. Stop wearing it and your cornea drifts back to its original shape over days to weeks.
So: LASIK is a procedure you have. Ortho-K is a routine you keep.
That is not a criticism of either. It is the trade, and which side of it suits you depends on your eyes and on what you want.
Side by side
| Ortho-K | LASIK | |
|---|---|---|
| Permanence | Temporary — maintained nightly | Permanent |
| Reversible? | Completely | No |
| Tissue removed | None | Yes |
| Surgery | None | Yes |
| Ongoing commitment | Nightly wear, daily cleaning | None after healing |
| Suits a thin cornea? | Often yes | Frequently rules it out |
| Suits an unstable prescription? | Yes — the lens is updated | No — needs stability |
| Appropriate for children? | Yes, widely | No |
| Slows myopia progression? | Yes | No |
| Main risk | Infection, ongoing but largely preventable | Surgical, one-time, some effects permanent |
| Cost shape | Fitting, then ongoing replacement | Larger one-off |
| If you change your mind | Stop wearing them | Nothing to stop |
When Ortho-K is the better choice
You are not a LASIK candidate. This is the most common reason people arrive at Ortho-K, and it is worth knowing before you conclude nothing can be done:
- A cornea too thin for LASIK. LASIK needs enough tissue to remove safely. Ortho-K removes none, so thickness is far less of an obstacle.
- A prescription still changing. LASIK requires stability, because reshaping an eye that is still becoming more nearsighted just means being nearsighted again around a new curve. Ortho-K simply gets updated.
- Dry eye. LASIK can worsen dry eye by cutting corneal nerves. Ortho-K does not cut anything, though a dry surface still needs assessing before overnight wear.
You want it reversible. Some people are not comfortable with a permanent, irreversible change to their eyes, and that is a legitimate preference rather than something to be talked out of. Ortho-K gives you the outcome with an exit.
You are under 18, or your child is. LASIK is not done on developing eyes. Ortho-K is, and it does a second job LASIK cannot: overnight corneal reshaping is one of the established approaches for slowing how fast myopia progresses. For a child whose prescription climbs every year, that matters more than the glasses-free days — see myopia control in children.
You are not ready to decide. Ortho-K is a way to find out what life without daytime correction is actually like, with nothing committed. A number of patients wear it for years and never revisit surgery; others use it and later choose LASIK once their prescription settles.
When LASIK is the better choice
Being straight about this matters more than selling a lens.
You do not want a nightly routine. This is the honest dividing line. Ortho-K asks you to insert a lens every night, clean it every day, replace the case, and keep follow-up appointments — indefinitely. If that sounds like a burden rather than a minor habit, LASIK’s appeal is real: it is done, and then it is done.
Your prescription is stable and your corneas are suitable. If you are a good surgical candidate and you want the problem permanently solved, that is exactly what LASIK is for.
You have had trouble with contact lenses generally. If handling lenses has never worked for you, adding an overnight lens is unlikely to be the answer.
We fit Ortho-K; we do not perform LASIK. If LASIK is the better route for you, we will say so and point you to a surgeon — there is no version of this where recommending the wrong option serves anybody.
When neither is right
One important exception, and it is the reason a lot of people end up here.
Both Ortho-K and LASIK assume a cornea that is regular to begin with. Ortho-K reshapes a regular cornea; LASIK reshapes a regular cornea. If your cornea is already irregular — keratoconus, a corneal transplant, post-surgical ectasia — then:
- LASIK is contraindicated. Removing tissue from an already thin, weak cornea risks accelerating the disease. This is one of the main reasons corneal topography screening exists before refractive surgery.
- Ortho-K is not the answer either. There is no regular shape to reshape into.
- Scleral lenses are. They vault over the irregular cornea entirely and replace it as the optical surface.
If you have been turned down for LASIK because of corneal shape rather than thickness, that is worth investigating properly — it is sometimes the first time anyone has looked closely enough to find keratoconus.
What each costs
Neither has a single price, and they are shaped differently.
LASIK is a larger one-time cost, billed by the surgical centre.
Ortho-K is a fitting cost — corneal mapping, custom lens design, training, follow-up — then ongoing lens replacement roughly annually plus solutions. Over enough years the totals converge, which is why the decision is rarely best made on price.

Working out which you are
The useful next step is measurement, not more reading. Corneal topography shows your corneal shape and thickness, which is what determines whether LASIK is even on the table and whether Ortho-K will work well. An ocular surface assessment shows whether dryness is going to be a factor either way.

Ortho-K vs LASIK
- What is the difference between Ortho-K and LASIK?
LASIK reshapes the cornea permanently by removing tissue with a laser — one procedure, and the change is not reversible. Ortho-K reshapes the cornea temporarily using a rigid lens worn overnight, and the effect is maintained only by continuing to wear it. Stop wearing Ortho-K lenses and your cornea returns to its original shape over days to weeks. LASIK is surgery you have once; Ortho-K is a routine you keep.
- Is Ortho-K safer than LASIK?
They carry different risks rather than one being straightforwardly safer. LASIK's risks are surgical and largely one-time — dry eye, night vision changes, and rarely more serious complications, some of which are permanent because tissue has been removed. Ortho-K's main risk is infection, which is ongoing for as long as you wear the lenses but is very largely preventable through hygiene, and it leaves nothing permanent behind. If reversibility matters to you, that is Ortho-K's real advantage.
- Can I have Ortho-K if I am not a LASIK candidate?
Often yes, and this is one of the most useful things to know about it. A cornea too thin for LASIK is frequently still a good candidate for Ortho-K, because Ortho-K removes no tissue. An unstable prescription rules out LASIK but is manageable with Ortho-K, since the lens can simply be updated. Dry eye that LASIK would worsen may still allow Ortho-K, though it needs assessing. The one exception is an already irregular cornea — keratoconus for example — where neither is appropriate and scleral lenses are the answer.
- Which is cheaper, Ortho-K or LASIK?
They are structured differently rather than one being simply cheaper. LASIK is a larger one-time cost. Ortho-K is a fitting cost followed by ongoing lens replacement and solutions, so over enough years the totals converge. The reasons to choose between them are usually clinical rather than financial — reversibility, candidacy, and whether your prescription is still changing.
- Is Ortho-K reversible and LASIK not?
Correct, and it is the central difference. Ortho-K reshapes only the outermost layer of corneal cells, which renew continuously, so the effect fades when you stop. LASIK removes corneal tissue permanently; the tissue does not grow back and the reshaping cannot be undone. That is why Ortho-K is appropriate for children whose eyes are still developing and LASIK is not.
- Can teenagers have LASIK or Ortho-K?
LASIK is generally not performed on teenagers, because it requires a stable prescription and eyes that are still changing will simply become nearsighted again around the new shape. Ortho-K is widely fitted in children and teenagers, both to correct vision and because overnight corneal reshaping is one of the established approaches for slowing how fast myopia progresses — which is a job LASIK does not do at all.
