Clearer daytime vision
Many suitable wearers can see through the day without glasses or daytime contact lenses while the overnight effect is maintained.
ORTHO-K LENSES
Clear days,
shaped overnight.
Specially designed lenses work while you sleep, helping suitable wearers see through the day without glasses or daytime contact lenses—without surgery.
Results vary. A detailed eye-health and corneal assessment is required before treatment.
A GENTLE CHANGE, WHILE YOU SLEEP
What is
orthokeratology?
Ortho-K is a non-surgical vision-correction method that uses custom rigid contact lenses during sleep.
The lenses gently and temporarily change the shape of the clear front surface of the eye—the cornea. You remove them after waking. The changed corneal shape can then focus light more clearly during the day.
The effect is not permanent. The lenses need to be worn on the schedule prescribed for you to maintain clearer daytime vision.
Conceptual educational illustrationHOW IT WORKS
Your cornea guides how light comes into focus.
- 01
Wear the custom lenses at night
Each lens is designed from detailed maps of your cornea.
- 02
A thin tear layer does the work
The lens and tears create gentle hydraulic forces that redistribute cells at the corneal surface.
- 03
Remove the lenses after waking
The temporary shape change can reduce short-sighted blur through the day.
WHAT ORTHO-K MAY OFFER
More freedom for the day.
More care behind the scenes.
No surgery
Ortho-K changes the front surface of the cornea temporarily. The effect gradually reverses when lens wear is stopped.
Freedom for active days
Swimming, sport and busy routines may feel simpler without glasses, although eye-safe habits still matter.
A myopia-management option
For some children with progressing myopia, Ortho-K may form part of a monitored plan to slow eye growth.
WHO MAY BE SUITABLE
A good fit starts with
the right assessment.
Age alone does not decide suitability. Eye health, prescription, corneal shape, expectations and reliable lens care all matter.
Active adults
People with myopia who want less dependence on glasses during work, sport or daily activities.
Children with progressing myopia
Selected children who can manage overnight lenses with committed adult supervision and regular reviews.
People avoiding surgery
Those looking for a reversible option and willing to maintain a consistent lens-wear and hygiene routine.
When Ortho-K may not suit
Active eye disease, significant dryness, unsuitable corneal shape or poor hygiene can make overnight wear inappropriate.
MYOPIA CONTROL WITH ORTHO-K
Clearer vision today. A closer watch on tomorrow.
Myopia means distance vision is blurred because the eye focuses light in front of the retina. In children, myopia can increase as the eye grows longer.
Research shows that Ortho-K can slow eye growth for many children compared with ordinary single-vision correction. It does not cure myopia, and the response is different for every child.
A good myopia-management plan includes measurements over time, healthy visual habits, outdoor time and discussion of all suitable options—not one lens in isolation.
Read the research summaryWHAT TO EXPECT
Your treatment,
one careful step at a time.
Ortho-K is an ongoing care process, not a one-time purchase. Early reviews are especially important while the fit and vision settle.
A detailed eye check
We discuss your vision, lifestyle and health, then examine the front of your eyes to confirm that overnight lens wear can be considered.
Corneal mapping
A painless scan maps the shape of each cornea. These measurements guide the design and fit of your lenses.
Your first lens fit
We assess how the lenses sit, explain realistic goals and teach safe insertion, removal, cleaning and storage.
Early morning reviews
Follow-up visits check your unaided vision, corneal response, lens condition and comfort while the effect develops.
Ongoing care
Regular reviews and replacement lenses help protect eye health and keep the fit working as intended.
WHY CHOOSE LENSWISE
Careful fitting. Clear guidance. Support that continues.
Ortho-K works best as a guided care process. LensWise combines detailed measurements, practical training and planned reviews so you understand each decision and feel confident with daily care.
Measurement-led lens design
Corneal mapping and eye-health findings guide whether Ortho-K is suitable and how each lens is fitted.
Realistic expectations
Benefits, limits, adaptation and the reversible nature of the treatment are explained before you begin.
Hands-on care training
Learn insertion, removal, cleaning and safe overnight habits with clear, practical guidance.
Planned follow-up
Early and ongoing reviews check vision, corneal response, comfort and lens condition over time.
CLEAR ANSWERS BEFORE YOU BEGIN
Questions are part of
good eye care.
These answers are general. Your examination and individual lens plan decide what is appropriate for you.
Is Ortho-K a surgery?
No. Ortho-K uses specially designed rigid gas-permeable lenses during sleep. It does not cut or permanently alter the eye, and its effect is temporary.
Will I never need glasses again?
That cannot be promised. Many suitable people achieve useful daytime vision without glasses, but results vary and the effect needs regular lens wear. Backup glasses may still be useful.
How quickly does it work?
Some change may be noticed after the first nights. Reaching stable vision can take longer and depends on your prescription, corneal shape and response to the lenses.
Is Ortho-K suitable for children?
It may be considered for some children with progressing myopia who can follow lens-care routines with close adult support. A full assessment is essential.
Is sleeping in contact lenses safe?
Overnight lens wear carries a risk of infection and other complications. Careful hand washing, correct cleaning, prescribed wearing times and prompt attention to pain, redness or light sensitivity are essential.
What happens if I stop wearing the lenses?
The cornea gradually returns towards its earlier shape, so the myopia correction wears off. You will need glasses or another form of vision correction again.
