Ortho-K (Orthokeratology)

Ortho-K lenses, also known as night-time or overnight contact lenses, OK lens, or eye retainers.

Ortho-K is (1) worn only during sleep to gently reshape the
cornea, (2) removed after a night of rest the following day, for (3) clear vision throughout the day, an alternative to glasses.

A safe and effective solution for myopia control for children to experience clear vision without glasses or contact lenses during the day; Ortho-K can effectively slow the progression of myopia in children by approximately 50%.

What do we mean by slowing myopia progression?

If a child's prescription (e.g. 100 deg) increases by 1 diopter (100 deg) per year, it could worsen by 5 (500 deg) diopters in 5 years, a significant decline in vision (600 deg). With Ortho-K, the progression could be reduced by about 50%, increasing by only 2.5 (250 deg) diopters instead over the 5 years.

This non-surgical intervention reduces the risk of myopia-related issues and support long-term eye health without the need for frequent prescription adjustments.

Common Questions About Ortho-K Lenses Answered

Why do parents go for Ortho-K over other myopia control programmes?

Parents often share these two key reasons associated with health and well-being of their children: (1) effective myopia control with minimal compliance, and (2) non-invasive enhancement to their child's self-esteem and lifestyle.

1. Effective Myopia Control with Minimal Compliance. Ortho-K lenses are worn only while sleeping, providing continued myopia control effectiveness throughout the night until removal in the morning. This routine not only ensures treatment effectiveness, but also encourages good habits in hygiene and sleep.

Unlike myopia control glasses or daytime contact lenses, which rely on the child’s daytime compliance, Ortho-K eliminates the risk of reduced effectiveness due to compliance issues e.g. a child's forgetfulness or insufficient wear time.

Therefore, parents who want to take proactive steps to slow rising rates of myopia effectively without relying on the child's compliance often choose Ortho-K.

2. Enhancing self-esteem and lifestyle.

On top of improving their child's eye health, Ortho-K provides a non-invasive solution for parents who are concerned about the impact of glasses on their child's self-esteem and lifestyle.

With Ortho-K allowing their children to enjoy sports and activities without glasses or daytime contact lenses, Ortho-K addresses self-esteem concerns especially for myopic children who may face teasing or bullying for wearing glasses.

Parents themselves also value the convenience and lifestyle benefits of their child being glasses-free.

These advantages make Ortho-K a preferred option for proactive parents aiming to manage their child's myopia effectively and holistically.

What should I expect during and after my Ortho-K appointment?

Aside from a comprehensive eye exam to check your eye health and vision, our qualified optometrist use a special equipment to "map" the highs and lows of your cornea.

Similar to how a map shows hills and valleys, this measures the natural shape of your cornea which we will use to design your Ortho-K lenses.

If you are deemed suitable
You can expect to collect your customised Ortho-K lenses within 2 weeks.

Ensuring quality Ortho-K care
Upon collection, you will need to return the next day for an overnight review after your 1st night of Ortho-K wearing. Followed by 1-week, 1-month, 3-month, and 6-month reviews.

We would guide you and emphasise hygiene and care instructions to minimise risks (as with any contact lens use), ensuring a comfortable and safe experience for your brand new glasses-free lifestyle.

Are Ortho-K lenses worth it?

Yes, Ortho-K lenses can be good for many individuals, especially children. These myopia control lenses offer a non-surgical solution for controlling myopia, enhancing vision without the need for daytime glasses or contacts. The convenience of overnight-only wear and the potential to slow down vision deterioration make them a valuable investment in eye health. Because Ortho-K works when someone is sleeping, it ensures treatment effectiveness while removing daytime compliance challenges.

How long does an Ortho-K lens last?

Ortho-K lenses typically last about a year. Their lifespan depends on factors like maintenance, usage, and individual eye health. Regular checks with your optometrist is essential to monitor the condition of the lenses and ensure optimal performance throughout their lifespan.

Is Ortho-K permanent or temporary?

Ortho-K is a temporary, safe and reversible approach in reshaping the cornea to provide clear vision. The lenses must be worn regularly overnight. After removing the Ortho-K lenses, vision is clear for 24 to 72 hours. Regular use is necessary to maintain clear vision without glasses or contacts during the day.

How does Ortho-K work?

How Does Ortho-K Lenses Work?

Orthokeratology uses specially designed lenses to reshape the cornea while you sleep. Much like a dental retainer, but a retainer for the eyes. Here’s a closer look at how the process works:

Corneal Mapping: The process of designing Ortho-K lenses begins with corneal mapping, where we use a corneal topographer to map out a detailed view of the cornea shape and curvature.

Lens Design: Based on the corneal map, we design rigid, gas-permeable lenses that are safe for overnight use, to gently reshape the cornea. These lenses reduce the need for glasses or daytime contact lenses.

Overnight Wear: You wear the contact lenses while you sleep, allowing your cornea to reshape throughout the night. This overnight process is comfortable and non-invasive. When you remove them in the morning, you’ll enjoy clear vision during the daytime.

Can adults use Ortho-K?

Yes, most definitely. Ortho-K lenses are suitable for adults.

Our orthokeratologist will share some important considerations such as compliance, eye health and many more during the consultation, and the difference in expectations compared to regular soft contact lenses.

The best way to determine if Ortho-K is right for you is to consult with an orthokeratologist like Amanda. She will assess your individual needs, expectations, and suitability for the care you receive.

Can children wear Ortho-K lenses?

Yes, children can wear Ortho-K lenses. Clinical studies show Ortho-K significantly slowing myopia progression by about 50%. Additionally, they reduce the risk of eye injuries from broken glasses or dislodged contacts during activities.

The daily 1-min cleaning routine also promotes self-discipline and proper eye hygiene, fostering healthy habits for overall eye health.

Can Ortho-K help with astigmatism?

Yes, Ortho-K lenses can help individuals with mild to moderate astigmatism. They reshape the cornea while sleeping. Individuals with mild and rapidly progressive myopia, with or without mild astigmatism, up to -8.00Ds of myopia and -2.00Ds of astigmatism, may be suitable for Ortho-K lenses. An eye examination is required before we can recommend contact lenses for astigmatism.

Do I need regular checks while using Ortho-K lenses?

Yes, regular visits are essential during the first few weeks when you start using Ortho-K lenses. These appointments allow our optometrist to monitor your eye health and ensure proper lens fit.

Our Ortho-K clients get unlimited consultations to ensure their eye health is well taken care of.

Does Ortho-K slow down myopia progression?

Yes, Ortho-K significantly slows down myopia progression, a growing concern among parents in Singapore due to the high rates of myopia.

Clinical studies indicate that it can reduce the rate of myopia worsening by approximately 50% in children. By reshaping the cornea overnight, Ortho-K lenses help control the elongation of the eyeball, which is a key factor in myopia progression.

Who is suitable for Ortho-K lenses?

Individuals Managing Myopia: Those with mild to rapidly progressive myopia (with or without mild astigmatism) can be potential candidates for Ortho-K lenses. The ideal age for managing myopia in children is between 6 and 12 years when progression is most pronounced.

Those Seeking Freedom from Glasses: Children and adults in Singapore looking to live without glasses can benefit from Ortho-K lenses. This option is particularly suitable for individuals who are not eligible for LASIK or have other reasons to avoid traditional corrective eyewear.

Active Individuals and Those in Challenging Environments: Sporty individuals or people working in dusty environments may find Ortho-K lenses particularly useful, as they offer clear vision without the discomfort or complications of regular contact lenses.

What are some tips for healthy vision?

Maintaining a healthy diet: Certain nutrients are essential for eye health.

Protecting your eyes from UV rays: Wear sunglasses that block UVA and UVB rays.

Practicing good vision habits: Take breaks from near work to prevent eye strain.

Get regular comprehensive eye exams: A comprehensive eye exam reviews the front, back, and pressure of your eyes, in addition to your vision. Early detection of any potential eye problems is crucial for proper eye care and maintaining good vision throughout your life. Certain eye conditions, such as glaucoma, may result in irreversible vision loss if detected and treated too late.
