Ortho-K, short for orthokeratology, is a non-surgical treatment that helps correct vision using specially designed contact lenses worn overnight. In Singapore, it’s gaining popularity, especially among parents with children who have myopia. But what is Ortho-K really about, and how does it work?
This beginner-friendly guide explores everything you need to know about Ortho-K in Singapore then its mechanism, benefits, eligibility, risks, and how to get started.
How Ortho-K Works: Reshaping Vision While You Sleep
Ortho-K lenses are rigid gas permeable contact lenses. You wear them while sleeping, and they temporarily reshape the cornea, the transparent front part of the eye. By morning, the cornea retains the new shape for the day, allowing clear vision without the need for glasses or contact lenses.
The process is safe, reversible, and most suitable for individuals with mild to moderate myopia (short-sightedness). Some people also experience correction in mild astigmatism.
Unlike LASIK, which uses lasers to permanently reshape the eye, Ortho-K offers a non-invasive and adjustable method. If you stop wearing the lenses, your eyes return to their original shape.
Why Ortho-K is Popular in Singapore
Myopia is a major public health concern in Singapore. Studies suggest that over 65% of children aged 12 have myopia, with the number expected to rise. Parents are actively seeking ways to slow this progression and that’s where Ortho-K comes in.
Key reasons for popularity:
- Control of childhood myopia progression
- Non-surgical and reversible
- Daytime freedom from glasses
- Appealing to active kids and adults in sports
- Effective alternative for those not eligible for LASIK
Singapore’s humid weather can also make daily contact lens wear uncomfortable. Ortho-K reduces dependency on daytime lenses, which can be a major relief.
Who Can Use Ortho-K in Singapore?
Ortho-K is primarily recommended for:
- Children between 6 to 18 years with progressing myopia
- Adults with mild to moderate short-sightedness (up to -6.00 diopters)
- Individuals with low levels of astigmatism
- People who play sports or have active lifestyles
- Patients who are not ready or suitable for LASIK surgery
However, it’s important to consult an optometrist trained in Ortho-K fitting. Each cornea is different, and a custom lens design is often required.
Benefits of Ortho-K Treatment
1. Daytime Vision Freedom
No glasses. No contact lenses. Wake up and see clearly all day.
2. Myopia Control in Children
Clinical research shows Ortho-K can slow the rate of myopia progression. This helps reduce the risk of future eye diseases like glaucoma and retinal detachment.
3. Safe and Reversible
Unlike permanent surgical procedures, Ortho-K can be discontinued any time.
4. Non-Invasive and Painless
No blades, no lasers. Only lenses while you sleep.
5. Suitable for Sports and Outdoor Activities
Great for swimmers, athletes, and children who find glasses restrictive.
What to Expect During Ortho-K Fitting in Singapore
Step-by-Step Process:
- Initial Consultation
Includes vision assessment, corneal topography (mapping the eye surface), and a suitability check. - Trial Lens Fitting
A custom lens design is ordered based on eye measurements. - First Overnight Wear
You wear the lenses for the first time while sleeping. Vision changes can be noticeable within days. - Follow-Up Visits
Several follow-ups are required in the first few weeks to ensure the lenses are working well. - Ongoing Maintenance
Good hygiene and routine lens care are crucial to avoid infections or discomfort.
Most optometry clinics in Singapore provide comprehensive Ortho-K packages that include consultations, lens fitting, and follow-ups.
Risks and Considerations
Like all contact lenses, Ortho-K comes with minor risks, especially if hygiene is poor. Potential issues include:
- Eye infections (e.g., microbial keratitis)
- Lens discomfort or dislodgement during sleep
- Temporary visual disturbances like halos at night
To reduce risk:
- Follow cleaning instructions strictly
- Attend regular eye checks
- Report any discomfort immediately
Children must be taught proper lens handling. Some parents assist younger kids with lens insertion and removal each day.
Cost of Ortho-K in Singapore
The cost of Ortho-K in Singapore typically ranges from SGD 1,800 to SGD 2,800 per pair of lenses, including consultation and follow-ups. Replacement lenses may be needed every 1-2 years.
While it may seem expensive upfront, many parents view it as an investment in long-term eye health, especially for kids with high myopia progression.
Some insurance or Medisave-linked vision plans may partially cover the cost, but this varies.
How Long Do the Effects Last?
After wearing the lenses overnight, the reshaped cornea provides clear vision for up to 16–24 hours. However, regular nightly use is required to maintain the results.
Skipping nights can result in blurred vision the next day. If Ortho-K is discontinued completely, the eye shape and vision return to their original state within a few days.

| Soft Contact Lenses | No | Yes (older kids) | No | Yes | Yes |
| LASIK | Yes | No | No | No | Yes |
| Ortho-K | No | Yes | Yes | Yes | Yes |
Getting Started with Ortho-K in Singapore
If you’re considering Ortho-K for yourself or your child, here’s how to begin:
- Search for licensed optometrists offering Ortho-K fittings in Singapore.
- Book an eye exam to assess myopia level and corneal shape.
- Discuss goals and lifestyle with your specialist.
- Start a trial period to evaluate results and comfort.

Conclusion
Ortho-K offers a powerful, non-surgical solution for clear vision and myopia control especially for children in Singapore facing rising rates of short-sightedness. With proper care, it can be a safe and effective way to improve daily life without glasses or daytime lenses.
It’s not just about convenience. It’s about preserving long-term eye health and providing freedom for kids and adults alike.
