What to Expect
What to Expect from Orthokeratology
The typical Ortho-K arc from consultation to stable all-day vision, including what the first week genuinely feels like.
This describes the typical course of treatment. It is not an account of any individual patient, and your own timeline and outcome may differ. Nothing here is a promise about your result.
This describes the typical arc rather than any individual patient. Every cornea responds slightly differently and some fits need more refinement than others, but the sequence and the rough timing hold for most people.
The single most useful thing to know in advance is that vision improves in stages rather than all at once, and that the in-between period is expected rather than a sign something has gone wrong.
Who this is typically for
- Children and teenagers whose nearsightedness is progressing
- Adults with low to moderate myopia who want daytime freedom without surgery
- Swimmers and athletes for whom daytime lenses are impractical
- People working in dusty or heavily air-conditioned environments
- Anyone not a candidate for laser surgery, or not old enough for it
How to prepare
The first appointment is considerably more productive when you bring the right things. This is what actually helps.
- Stop wearing soft contact lenses for at least a week before the consultation, and longer for rigid lenses. Lenses reshape the cornea and distort the topography measurements the whole fit depends on.
- Bring every previous prescription you can find, and previous corneal topography if you have had it.
- Bring your glasses. You will be wearing them during the adaptation period and it is worth checking the prescription is current.
- Come with questions written down. The consultation covers candidacy, cost, the schedule and the handling routine, and it is a lot to absorb in one sitting.
- For a child, bring the child. Motivation matters more than age, and a great deal of the assessment is whether this particular child will manage the routine.
- Allow an hour for the first appointment and plan not to rush afterward.
Stage by stage
- Visit 1
1. Consultation and corneal mapping
A full eye health examination plus corneal topography, which maps the surface curvature of your cornea in detail. This is the visit that determines candidacy, and we would rather tell you no here than after you have paid for lenses.
Prescription range matters and corneal shape matters just as much. Some corneas simply do not respond well, and the topography map shows that quickly. Expect roughly an hour.
- Visit 2
2. Dispensing and handling training
Custom lenses arrive designed to your individual measurements. These are made for one eye of one person, not selected from stock.
You are taught insertion, removal and care until you are genuinely confident rather than until we have demonstrated it. For a child we teach the parent too and expect supervision at first. Most people are comfortable within one session.
- Night 1
3. The first night
The lenses feel like something in your eye. That is normal and it is the part people are least prepared for. Almost everyone adapts within a week and most report forgetting they are wearing them by the second.
You sleep in them and remove them in the morning. Most people notice a clear improvement immediately, though vision will not yet be stable through the whole day.
- Day 2
4. First morning check
We see you the morning after your first night, with the lenses still in where possible, to confirm the fit is centring correctly and to check corneal health.
This is the appointment that catches an off fit early, when it is easy to correct. It is also where we answer the questions that only occur to you after actually wearing them.
- Weeks 1 to 2
5. Vision stabilises
This is the period people find most confusing without warning. Vision is typically good in the morning and softens somewhat by evening while the cornea settles into its new shape.
It resolves. Most people reach stable all-day correction within one to two weeks. Lower prescriptions usually stabilise faster than higher ones.
- Weeks 2 to 6
6. Refinement
Follow-up visits while vision settles, with lens parameters adjusted where needed. Several iterations is normal and is part of the process rather than a sign anything went wrong.
By the end of this period most patients are wearing the lenses nightly without thinking about it, and seeing clearly all day with nothing on their eyes.
- Ongoing
7. Long-term care
Regular reviews to monitor corneal health and maintain the fit. Lenses are typically replaced annually.
For children, these visits also track myopia progression, which is the second reason the treatment is being done and the one parents came for.
What we tell every patient up front
These are the things worth knowing before you commit rather than discovering afterward.
- The effect is temporary. Stop wearing the lenses and your cornea returns to its original shape within days, and your original prescription comes back.
- It requires nightly wear. Occasional missed nights are usually fine, and skipping regularly means the correction never fully stabilises.
- It works best up to about minus six dioptres with mild to moderate astigmatism. Beyond that, results become less predictable.
- The main risk is contact lens related infection, managed through correct fitting, genuine hygiene and keeping to the review schedule.
- Some corneas do not respond well. We would rather find that at the topography stage than after you have committed.
What it costs
The programme cost covers the fitting, custom lenses, all scheduled follow-ups and the care kit, not just the first appointment. We give you the complete figure in writing at the consultation.

Common questions about the process
How quickly will I see clearly?
Most people notice a clear improvement after the first night. Full stable all-day correction typically takes one to two weeks as the cornea settles, and vision may soften by evening during that period.
Does it hurt?
No. There is an awareness of the lens for the first few nights, similar to any rigid lens, and it fades quickly. Pain is not normal at any stage and is a reason to call us.
How many appointments should I expect?
Typically five or six across the first six weeks, then reviews. We schedule them around your availability, and for patients driving from further out we consolidate where it is clinically safe to do so.
What if I decide to stop?
Your cornea returns to its original shape within days to a couple of weeks and nothing is permanently changed. That reversibility is one of the main reasons parents choose it for children.
Book an appointment with a doctor who has time for you
We schedule 2 patients an hour, so your exam is unhurried and your questions get answered. Most patients are seen within a few days.
