Orthokeratology (Ortho-K/OK lens) is the fitting of specially designed gas-permeable contact lenses you wear overnight. While you are asleep, the lenses help reshape the front surface of your eye (cornea) so you can have better vision the following day upon removing the lenses when you wake up.

Orthokeratology may be suitable for adults seeking an alternative to eyeglasses or refractive surgery, and especially for those who experience dry eyes with soft contact lenses.

But orthokeratology is not only for adults. Ortho-K lenses are generally recommended for myopia control in childrenwith progressive myopia. Many studies have also shown the effectiveness of these lenses in managing and stabilising myopia in children. It also allows children who do not tolerate glasses well or have an active lifestyle to be glasses-free throughout the day while having myopia control present at the same time.



One of the benefits of using Ortho-K lenses is that they can help address myopia and astigmatism in children and adults. They may also minimise the need for glasses or contact lenses during the day, making the lenses a potential solution for better vision.


With Ortho-K lenses, you may worry less about surgical risk or downtime. This is a non-surgical approach to help reshape your cornea, unlike LASIK, which involves the removal of corneal tissue.


Ortho-K lenses may help manage myopia progression in children and adults. Myopia can lead to other eye conditions, such as cataracts and glaucoma. Therefore, you should seek professional guidance about using OK lenses for myopia.


Corneal reshaping with an OK lens is reversible with minimal risks when combined with proper care and professional guidance. You may discontinue wearing the lenses at any time, provided you are ready to put on your spectacles or contact lenses.



1. Consultation & Assessment

The optometrist will begin the consultation with a pre-assessment to gauge your suitability for Ortho-K lenses and discuss the expected outcomes.

2. Collection of Lenses

Lenses will be ready for collection within two weeks of purchase. During the collection, the optometrist will guide you on proper OK lens insertion, removal, and care techniques.

3. Follow-up Reviews

It is advisable that you attend regular check-ups to ensure optimal fit and efficacy. The optometrist may schedule these appointments after your first overnight use, followed by one-week, one-month, three-month, and half-annual reviews.


The comfort level of the Ortho-K lenses may vary from person to person. However, on the first night of use, there may be slight discomfort, but the comfort level may improve with continued use. Feel free to consult an optometrist to learn how to minimise the discomfort when using your Ortho-K lenses.


When considering vision correction in Singapore, Ortho-K and LASIK are two popular options, each with its own benefits.

Ortho-K is a non-surgical approach involving overnight wear of custom-designed lenses that helps reshape the cornea temporarily. This method is reversible and may be suitable for those who prefer a non-invasive option or are not candidates for surgery due to age, lifestyle, or corneal thickness. Ortho-K may also be recommended for children for myopia control.

LASIK, on the other hand, is a surgical procedure that may help to reshape the cornea to improve vision permanently. It is a quick approach with a longer recovery period and may be suitable for adults looking for a permanent fix to their refractive errors. However, it may not be suitable for everyone, especially those with certain medical conditions or thinner corneas.

While Ortho-K may offer a flexible and reversible approach, especially for children and those hesitant about surgery, LASIK provides a more permanent correction with surgical risks and limitations. It is advisable that you consult a professional optometrist to learn about your options.


Understanding the cost of Ortho-K lenses in Singapore is crucial when considering it as a vision correction option. The price reflects the customisation and potential care involved in the process. Let’s delve into the details:

  • Customisation: Each Ortho-K lens is designed to the individual's specific eye shape and vision requirements, ensuring optimal comfort and effectiveness. This personalisation is a key factor in the overall cost.
  • Ongoing Professional Care: The cost may include not just the lenses but also the professional services of the optometrists. Regular follow-ups ensure the lenses perform as intended and allow adjustments as needed.
  • Long-term Benefits: Investing in Ortho-K is not just about immediate vision correction; it's about ongoing eye health, which is especially crucial for children in managing myopia progression.

While the initial cost may be higher than regular glasses or contact lenses, Ortho-K offers a potential blend of safety, effectiveness, and convenience, especially for myopia control in children and adults seeking a non-surgical solution.
