The Benefits of Ortho-K (Orthokeratology) Lenses
Ortho-K at EMME Visioncare is led by Jaycob Chin, FIAOMC, Fellowship of the American Academy of Orthokeratology & Myopia Control (AAOMC).
Orthokeratology (Ortho-K) lenses gently reshape the cornea overnight, so many wearers can see clearly during the day without glasses or daytime contact lenses. The main benefits of Ortho-K are non-surgical, reversible vision correction, freedom from daytime lenses, and — for children — a way to help slow the progression of short-sightedness (myopia). Suitability and results vary from person to person and are confirmed through a detailed assessment.

Ortho-K is a non-surgical, reversible form of vision correction available to adults and children in Singapore. Below are the key benefits to consider.
Key Benefits of Ortho-K Lenses
1. Clear daytime vision without glasses or contacts
Ortho-K lenses are worn during sleep and removed in the morning. With the cornea temporarily reshaped, many people enjoy functional daytime vision without relying on glasses or daytime contact lenses. The degree of correction depends on your prescription and eye characteristics, which we assess before fitting.
2. Non-surgical and fully reversible
Ortho-K does not permanently alter the eye. If lens wear is stopped, the cornea gradually returns to its natural shape over several days. This makes it a suitable option for people who prefer to avoid surgery, or whose prescription has not yet stabilised.
3. Can address more than short-sightedness
Ortho-K is most commonly used for myopia (short-sightedness). In suitable cases it can also help manage astigmatism and mild long-sightedness (hyperopia) or presbyopia. Your optometrist will confirm whether your prescription falls within a treatable range.
4. Lenses are worn only at night
Because the lenses are worn while you sleep, they do not interfere with daytime activities such as sport, swimming or screen work. People who find daytime soft lenses drying in air-conditioned or screen-heavy environments sometimes find overnight wear more comfortable.
5. Supports myopia control in children
For children, Ortho-K offers a second benefit beyond clear vision. Peer-reviewed studies report it can slow the rate of childhood myopia progression by roughly half on average, by reducing the abnormal lengthening of the eye. Slowing progression can help lower the long-term risk of eye conditions linked to high myopia. Ortho-K is one of several myopia control options we offer. Progression can be slowed and managed, not cured.
6. A safe option when fitted and cared for properly
Infection is the main risk of wearing any contact lens, including Ortho-K. Published research estimates the incidence of microbial keratitis (a rare corneal infection) at roughly 5 to 14 per 10,000 wear-years — comparable to daily soft contact lens wear — with risk strongly tied to hygiene and compliance. Following the handling, cleaning and review schedule your optometrist provides keeps this risk low. You can read more about the safety of Ortho-K.
7. Flexible and reviewable
Ortho-K can be paused or stopped at any time, and it does not rule out laser surgery later if you choose it (after a period without lens wear). For children, keeping the prescription lower during the growing years can keep more options open in adulthood.
Is Ortho-K right for you?
The benefits above apply to most suitable candidates, but Ortho-K is not for everyone — prescription strength, corneal shape, eye health and lifestyle all matter. A detailed Ortho-K assessment is the only way to confirm suitability. If you are weighing up the investment, see our guide to Ortho-K pricing.
Frequently Asked Questions
How quickly does Ortho-K work?
Many people notice improved vision after the first night of wear, with vision stabilising over the first one to two weeks as the eyes adapt. Lower prescriptions typically settle faster than higher ones.
Is Ortho-K suitable for children?
Yes. Children are often good candidates because Ortho-K can both provide glasses-free daytime vision and help slow myopia progression. There is no fixed lower age limit; suitability is based on the child's eyes and ability to follow the care routine with parental support.
Does the effect last all day?
For many wearers, vision stays clear through a full day, though some notice a slight reduction towards the evening, especially with higher prescriptions. Lens design accounts for a small expected amount of daytime regression.
What happens if I stop wearing the lenses?
The effect is temporary. If you stop wearing the lenses for a few days, the cornea gradually returns to its original shape and your previous prescription returns. Nothing is permanently changed.
