Orthokeratology (Ortho-K) –
Overnight Vision Correction at Parkhurst and Co
Wake up to clear vision — no glasses, no daytime contact lenses.
Orthokeratology (Ortho-K) is a safe, non-surgical treatment that uses specially designed overnight contact lenses to gently reshape the front of the eye while you sleep.
By morning, you can enjoy clear vision all day long without needing glasses or contact lenses.
Ortho-K is suitable for adults and children and is also an excellent option for myopia management, helping reduce how quickly short-sightedness progresses.
How Ortho-K Works
-
You wear custom-made Ortho-K lenses overnight.
-
While you sleep, they gently reshape the cornea (the front surface of the eye).
-
When you remove the lenses in the morning, you can see clearly throughout the day.
-
The effect is temporary, so the lenses must be worn every night to maintain clear vision.
There is no surgery, no recovery time, and the treatment is fully reversible.
Who Is Ortho-K Suitable For?
Ortho-K is a great option for:
-
People who want clear daytime vision without glasses
-
Active individuals (runners, cyclists, gym users, swimmers)
-
Those who struggle with dry eyes when wearing daytime lenses
-
Children and teenagers needing myopia control
-
Adults up to approx. –5.00D of short-sightedness (depending on corneal shape)
We will confirm suitability during your consultation.
What Happens at an Ortho-K Consultation?
1. Assessment & Measurements
We check your prescription, corneal shape and eye health using corneal topography to determine whether Ortho-K is suitable.
2. Lens Design & Ordering
If suitable, we design personalised Ortho-K lenses based on your eye’s unique measurements.
3. First Fitting
When the lenses arrive, you’ll be shown how to insert, remove and care for them safely.
4. First Morning Review
You return the next day (after your first night of wear) so we can check vision, fit and corneal response.
5. Follow-Up Care
Regular reviews ensure the lenses continue working safely and effectively.

FAQs
1. What exactly are Ortho-K lenses?
They are specially designed hard contact lenses worn overnight to gently reshape the cornea, giving clear daytime vision without glasses or lenses.
2. How quickly will I notice a difference in my vision?
Many people notice improvement after the first night, with full correction typically achieved within a few days to one week.
3. Can Ortho-K correct all prescriptions?
Most short-sighted prescriptions up to about –5.00D can be treated. Suitability depends on your corneal shape, prescription and eye health.
4. Is Ortho-K safe for children?
Yes. Ortho-K is widely used in children as part of a Myopia Management programme and has a strong safety record when properly supervised.
5. Will the effect last all day?
Yes—once treatment is established, clear vision typically lasts all day. If you skip a night, vision may begin to soften.
6. Will the reshaping damage my eyes?
No. The reshaping is temporary and reversible. When the lenses are not worn, the cornea gradually returns to its natural shape.
7. What if I have dry eyes with normal contact lenses?
Ortho-K may actually be more comfortable because the lenses are only worn at night when your eyes are closed, reducing dryness and irritation.
8. How often will I need check-ups?
After initial fitting and follow-up visits, most patients attend regular reviews every 6–12 months to ensure continued safety and performance.
9. Can I swim or play sports with Ortho-K?
Yes. This is one of the biggest benefits—clear vision with no lenses in your eyes, ideal for swimmers, footballers, gym users and runners.
10. Is Ortho-K a permanent treatment?
No. If lens wear stops, your prescription will gradually return. It is completely reversible and non-surgical.
11. Is Ortho-K painful or uncomfortable?
Most people adapt quickly. As the lenses are worn while sleeping with closed eyes, awareness is usually minimal.
12. Does Ortho-K help slow myopia progression?
Yes. Ortho-K is clinically proven to help slow the rate of short-sightedness in children and teenagers.
13. What happens if I accidentally lose a lens?
We can order a replacement quickly. Some patients choose to have a spare pair once they are stable.
