While corrective lenses, like glasses and contact lenses, remain widely used for those with myopia, other alternatives have emerged, like Orthokeratology or Ortho-K.
What sets Ortho-K apart is its ability to address vision problems throughout the day without the need for glasses or daytime contact lenses. It is considered a non-pharmacological option for myopia control.
But does Ortho-K align with your vision needs? In order to determine if this is the right choice, it’s important to learn more about how it works and who could potentially benefit from it.
How Does Ortho-K Work?
Ortho-Kworks by using gas-permeable contact lenses that gently reshape the cornea while you sleep. These lenses apply slight pressure to the cornea, flattening it to address myopia (nearsightedness).
The process is temporary, meaning the cornea gradually changes into its original shape if the lenses are not worn regularly. Therefore, to aid with vision during the day, it is essential to wear Ortho-K lenses every night.
What Type of Lenses Are Used?
The lenses used in Ortho-K are known as "rigid gas-permeable" (RGP) lenses. They are custom-made to fit each patient’s eyes based on detailed corneal topography measurements.
How Long Does an Ortho-K Lens Last?
Ortho-K lenses last for about 1-2 years, depending on lens care and hygiene practices. However, we recommend that lenses be changed annually.
Benefits of Ortho-K
Some of the advantages of wearing Ortho-K include:
1. Freedom from Glasses and Daytime Contact Lenses
A primary advantage of Ortho-K lenses is the freedom they provide during the day. This is because after wearing the lenses overnight, you can potentially acquire optimal vision without the need for glasses or daytime contact lenses.
2. Myopia Control in Children
One of the significant benefits of Ortho-K, particularly for children, is helping slow down the progression of myopia. Studies have shown that wearing Ortho-K lensescan help reduce the progression rate of myopia in children and teenagers, making it a notable option as myopia control lenses.
3. Ideal for Active Lifestyles
Ortho-K lenses can be beneficial for individuals with active lifestyles, including athletes and outdoor enthusiasts. Without needing glasses or daytime contact lenses, there’s less worry about lenses falling out or glasses getting damaged during physical activities.
Who is a Good Candidate for Ortho-K?
Some of the deal candidates for this myopia control option include:
- Individuals with Mild to Moderate Myopia
- Children and Teenagers with Progressive Myopia
- Athletes and Individuals with Active Lifestyles
- Individuals who work in dusty environments but do not want or cannot have refractive surgery

The Ortho-K Process
The process of acquiring Ortho-K lenses will involve the following:
1. Initial Consultation and Eye Exam
You should first undergo a comprehensive eye exam to determine if you are a suitable candidate for Ortho-K. During this exam, your optometrist will assess your vision, measure the shape of your cornea, and discuss your vision needs.
2. Lens Fitting and Customisation
Once it's determined that Ortho-K is right for you, custom lenses will be designed based on the measurements of your cornea. The lenses will be tailored to your specific needs to ensure a perfect fit and optimal comfort.
3. Overnight Wear and Follow-Up Visits
You'll wear the lenses overnight, and after just one night of use, you should notice a significant change in your vision. Follow-up visits are essential to monitor the results of the lenses and to ensure your eyes remain healthy.
4. Importance of Hygiene and Lens Care
Proper care of your Ortho-K lenses is crucial for maintaining eye health. You'll need to follow a cleaning routine to prevent infections or lens damage. Your optometrist will provide detailed instructions on how to clean and store the lenses.
Cost and Considerations
The price of Ortho-K in Singaporegenerally starts at about S$2,000, and the annual cost of lens replacements starts at about S$800. Its exact price will depend on a few factors, including your prescription.
