Is Ortho-K suitable for my child?
Ortho-K is suitable for most people with nearsightedness (myopia), astigmatism and farsightedness. Our Ortho-K eye lenses are made with an advanced gas permeable material which allows for high breathability and provides adequate oxygen to the tissues in the eyes, hence it is also recommended for people with dry eyes or allergies.
Ortho-K is also popular with people whose lifestyles require excellent vision, such as pilots, professional athletes and lifeguards.
Age-wise, our patients range from as young as 4 years old, up to 67 years old.
Is Ortho-K safe?
Ortho-K is considered a safe eye treatment for myopia because of its non-surgical and reversible nature. The risk of infection is relatively low too. However, do note that Ortho-K should only be performed by certified eye specialists like our orthokeratologists at Titus Eye Care.
Is Ortho-K painful?
Wearing Ortho-K lenses is similar to wearing contact lenses, meaning your child will not feel any pain. Furthermore, these eye braces are worn to sleep, which decreases the lens sensation compared to when the eyes are open.
As with the wearing of other types of contact lenses, proper lens care and handling are important to maintain eye health.
How are Ortho-K lenses different from regular contact lenses?
Our Ortho-K lenses are specially designed to exert a gentle force on the eye to reshape it, leading to clearer vision. Each pair is created with our advanced Myo-Control technology, which maps the eyes’ details out accurately, to make sure they fit the unique shape of the patient’s eyes.
Does it really help to slow down myopic progression?
Yes. Ortho-K has been shown to have up to 77% effectiveness in controlling myopia progression and is a much sought-after way of myopia control treatment by parents for their kids.
How long will it take for good vision to set in?
The patient should experience immediate improvement in vision within minutes. After as little as one night of wearing the Ortho-K lenses, the patient will be able to see clearly. In the case of children, their corneas are more easily “moulded”, which means that vision improvement takes effect even quicker than adults.
Patients with higher prescriptions may take a longer time to regain clear vision. In rare cases that the eyes don’t respond to the eye braces, our orthokeratologists will re-evaluate the design of the lenses.
How long is the Ortho-K treatment process?
The Ortho-K treatment process depends on the wearer’s myopia condition and its complexity. Expect 4 to 6 visits over a 3 to 6 month period. The first follow-up visit will be on the next day after the Ortho-K lenses have been prescribed.
What is the difference between Ortho-K and LASIK?
The concept behind both procedures is similar, in that both alter the corneal curvature of the eyes, to allow light to be refocused onto the retina. However, Ortho-K is non-surgical whereas LASIK involves using laser technology to ablate part of the corneal tissue.
Ortho-K uses a mould to reshape the corneal curvature overnight and is reversible and relatively risk-free. On the other hand, LASIK, being a permanent surgery, has higher risks of scarring and weakening the corneal foundation.
How has the Ortho-K technology improved since 10 years ago?
There have been significant improvements over the past 10 years. The introduction of new materials with higher permeability for the construction of the lenses means a reduced risk of corneal infection. New corneal topographic technology also allows for more accurate and faster mapping of the cornea.
Does this mean I have to wear Ortho-K lenses for the rest of my life?
How often Ortho-K lenses need to be worn vary from person to person. Some patients reported having to wear them three times per week, while others need them every night. It is worth noting that there has been progress in the Ortho-K field—eye braces that require only once-a-week wearing are currently under testing.
Can any eye care specialist design Ortho-K?
No. Ortho-K moulds are not like normal contact lenses. It is important to consult a fully-accredited orthokeratologist because the moulds require a great deal of knowledge in the design, fitting and review process.

How long do Ortho-K moulds last?
With proper maintenance and care, the moulds can last up to 4 years. However, it is recommended to have them replaced every other year. Our Ortho-K specialists will be able to assist to review if your Ortho-K moulds need to be replaced.
How much does Ortho-K cost?
As Ortho-K is a longer process than other invasive myopia control techniques such as LASIK surgery; and requires the wearer to come back for follow-ups over a 6-month period, it can mean a higher cost.
In addition, the GP material used for Ortho-K moulds are more costly than the usual contact lenses. Prices are also dependant on the experience and skills of the orthokeratologist, and the complexity of the case.
What if Ortho-K does not work well for me?
The patient can simply stop wearing the Ortho-K lenses. Most Ortho-K specialists offer warranty in the form of a partial refund and a pair of quality glasses in the event that Ortho-K does not work well. Reversibility and money-back guarantee are the main differences between LASIK and Ortho-K.
