Why Parents Are Asking About Ortho-K Lenses
For many parents in Singapore, managing myopia in children is no longer just about glasses. Orthokeratology, or Ortho-K lenses, are gaining popularity as a safe, non-surgical option that gives children clear daytime vision without the need for spectacles or contact lenses. Worn only while sleeping, Ortho-K lenses gently reshape the cornea overnight. By morning, the lenses are removed, leaving the child with sharp vision for the day.
Beyond convenience, Ortho-K has another important role: slowing down the progression of myopia. This makes it an attractive choice for families concerned about the long-term risks of high myopia, such as glaucoma or retinal detachment.
How Ortho-K Work
Orthokeratology (Ortho-K) Lenses for Children are specially designed rigid gas permeable contact lenses. They temporarily flatten the central cornea overnight, changing how light focuses on the retina. By correcting the eye’s focusing power during sleep, children wake up with clear vision that lasts throughout the day.
This corneal reshaping effect is reversible and requires consistent overnight wear to maintain results. When fitted and monitored by an eye specialist, Ortho-K is safe and effective for children.
Benefits of Orthokeratology (Ortho-K) Lenses for Children
Spectacle-free daytime vision: ideal for sports, outdoor play, and active lifestyles.
Clinically proven myopia control: research shows Ortho-K can slow progression by 30–60%.
Suitable for astigmatism: customised designs can correct both myopia and astigmatism.
Non-surgical and reversible: unlike LASIK or other permanent procedures, effects stop once lenses are discontinued.
Who Is Suitable for Ortho-K?
Children may be candidates for Ortho-K if they:
Have mild to moderate myopia (typically up to -6.00 diopters)
Have astigmatism (up to certain limits, depending on corneal shape)
Are motivated to avoid wearing glasses or daytime contact lenses
Are responsible enough, with parental supervision, to manage lens care and hygiene
The Fitting and Care Process
Comprehensive assessment: eye mapping and corneal topography determine suitability.
Lens fitting and training: child and parents are taught lens insertion, removal, and cleaning.
Initial trial period: follow-up reviews are scheduled to fine-tune the fit and monitor eye health.
Ongoing care: regular check-ups every 3–6 months ensure continued safety and effectiveness.
Frequently Asked Questions
1. Is Ortho-K safe for kids?
Yes. When prescribed and monitored by a trained eye specialist, Ortho-K is safe for children. The key to safety lies in strict hygiene and regular follow-ups.
2. At what age can children start Ortho-K?
Children as young as 7 or 8 may be considered suitable if they can handle lenses responsibly, with parental support.
3. How effective is Ortho-K in slowing myopia?
Studies show Ortho-K can slow myopia progression by 30–60%, making it one of the most effective non-surgical options available today.
4. Can Ortho-K correct astigmatism?
Yes, specially designed Ortho-K lenses can correct certain levels of astigmatism in addition to myopia.
5. What if my child forgets to wear the lenses at night?
The reshaping effect is temporary. If lenses aren’t worn, vision gradually returns to the original prescription within 24–48 hours.
6. How comfortable are the lenses?
Children often take a few nights to adapt, but most report little to no discomfort after the adjustment period.
7. Are there risks with Ortho-K?
As with all contact lenses, risks include infection or corneal abrasion, but these are rare when hygiene and follow-up care are maintained.
8. Is Ortho-K covered by Medisave or insurance?
No, Ortho-K is not claimable under Medisave. Some private insurance wellness plans may provide partial coverage.
