What is OrthoKeratology?
Orthokeratology, commonly known as Ortho-K, is a non-surgical vision correction treatment that uses specially designed overnight contact lenses to gently reshape the front surface of the eye (cornea).
These lenses are worn while sleeping and removed in the morning, allowing clear vision throughout the day without glasses or daytime contact lenses.
Ortho-K is commonly used to correct short-sightedness (myopia) and may also help slow its progression in children.
How Does Ortho-K Work?
Ortho-K lenses are custom-made rigid gas permeable lenses designed to temporarily reshape the cornea overnight.
By gently altering the shape of the cornea, the lenses help focus light correctly onto the retina.
When the lenses are removed in the morning, many patients experience clear vision during the day without needing glasses or contact lenses.
The effect is temporary, so lenses must be worn nightly to maintain results.
Who is Orthokeratology Suitable For?
Ortho-K may be suitable for:
-
Children with progressive myopia (short-sightedness)
-
Patients who want freedom from glasses during the day
-
People who play sports or lead active lifestyles
-
Patients who are not suitable for laser eye surgery
A comprehensive eye examination is required to determine whether Ortho-K is appropriate.
Benefits of Orthokeratology
Ortho-K offers several advantages:
-
Clear daytime vision without glasses or daytime contacts
-
Non-surgical and reversible
-
Can help slow myopia progression in children
-
Ideal for sport, swimming, and active lifestyles
Many patients enjoy the convenience of waking up with improved vision.
What Happens During an Ortho-K Consultation?

-
Comprehensive eye examination
-
Detailed corneal topography (mapping of the eye surface)
-
Custom lens fitting
-
Instruction on lens care and insertion

Follow-up appointments to monitor eye health and results
Regular monitoring is important to ensure the lenses are working safely and effectively.
Are Ortho-K Lenses Safe?
When prescribed and monitored by an eye care professional, Ortho-K lenses are considered safe for appropriate candidates.
Ortho-K lenses are custom-fitted for your eyes. They are a non-invasive and reversible option for fixing your vision without glasses or surgery.
However, regular follow-up appointments and monitoring by your optometrist are essential to maintain eye health.
