Orthokeratology Singapore: Complete Parent's Guide to OK Lenses and Myopia Control in Children (2026)

Introduction

If your child is becoming increasingly short-sighted, you may have heard about Orthokeratology, commonly known as Ortho-K or OK Lenses.

Parents are often surprised to learn that myopia (short-sightedness) is not simply about wearing stronger glasses every year. Progressive myopia can increase the lifetime risk of retinal detachment, glaucoma, myopic macular degeneration and other sight-threatening eye diseases.

The good news is that modern myopia control treatments can significantly slow down the progression of myopia.

Among the most effective options available today is Orthokeratology.

At The Eye Clinic by Dr Cheryl Lee, Orthokeratology is not simply about helping children see without glasses. It is part of a comprehensive doctor-led myopia control programme designed to slow eye growth, reduce future eye health risks and preserve long-term vision.

What Is Orthokeratology?

Orthokeratology (Ortho-K) uses specially designed rigid gas permeable contact lenses that are worn while sleeping.

These custom-made lenses gently reshape the front surface of the eye overnight.

When your child removes the lenses in the morning, they can enjoy clear vision throughout the day without glasses or daytime contact lenses.

The effect is temporary and reversible, which means the lenses need to be worn regularly at night to maintain clear daytime vision.

How Do OK Lenses Work?

In a short-sighted eye, light focuses in front of the retina instead of directly on it.

Ortho-K lenses temporarily reshape the cornea so that light focuses correctly on the retina during the day.

More importantly, Orthokeratology changes how light falls on the peripheral retina. This altered focus pattern appears to slow down the elongation of the eyeball, which is the main reason myopia worsens in children.

This is why Orthokeratology is considered both a vision correction treatment and a myopia control treatment.

Does Orthokeratology Really Slow Myopia?

Yes.

Multiple clinical studies have shown that Orthokeratology can slow myopia progression by approximately 40% to 60% compared with ordinary glasses.

At The Eye Clinic, we frequently use combination therapy where appropriate, combining Orthokeratology with other evidence-based treatments to achieve even stronger myopia control.

The goal is not simply to reduce dependence on glasses but to minimise the rate at which the eye continues to grow longer.

Why Is Myopia Control So Important?

Many parents think:

"My child only needs a stronger pair of glasses."

Unfortunately, every increase in myopia means the eye becomes longer.

The longer the eye becomes, the higher the lifetime risk of:

• Retinal detachment

• Myopic macular degeneration

• Glaucoma

• Early cataracts

• Irreversible vision loss later in life

Modern myopia control focuses on reducing these future risks by slowing the progression of myopia during childhood.

The earlier treatment begins, the better the long-term outcome.

Who Is Suitable For Orthokeratology?

Orthokeratology may be suitable for:

• Children whose myopia increases every year

• Children aged approximately 6 years and above

• Children involved in sports

• Swimmers

• Active children who dislike glasses

• Children with a strong family history of high myopia

• Teenagers seeking freedom from daytime glasses

A detailed examination is necessary to determine whether your child is a suitable candidate.

Why Parents Choose OK Lenses

1. No Glasses During The Day

Children enjoy clear vision throughout the day without spectacles.

Many children find this particularly useful for sports and outdoor activities.

2. Proven Myopia Control

Orthokeratology is one of the most researched and effective methods of slowing myopia progression.

3. Non-Surgical

Unlike LASIK or other refractive procedures, Orthokeratology is completely reversible.

4. Improved Confidence

Many children enjoy the freedom of not having to wear glasses every day.

Why Choose A Doctor-Led Orthokeratology Clinic?

This is one of the most important questions parents should ask.

In many clinics, Orthokeratology is managed primarily by an optometrist.

At The Eye Clinic, Dr Cheryl Lee personally supervises the myopia management programme as a specialist eye doctor.

This means your child receives:

• Medical oversight from an ophthalmologist

• Monitoring of eye growth and myopia progression

• Management of dry eye disease

• Assessment for inflammation and infection

• Long-term eye health surveillance

• Access to the full range of myopia control options

Our philosophy is simple.

The objective is not merely to fit a lens.

The objective is to control myopia as effectively as possible.

The Eye Clinic's Approach To Myopia Control

Dr Cheryl Lee is internationally recognised for her work in myopia management and vision correction.

Every child receives an individualised plan which may include:

• Orthokeratology

• Low-dose atropine therapy

• Myopia control spectacles

• Lifestyle modification

• Outdoor activity recommendations

• Regular monitoring of eye growth

We believe there is no one-size-fits-all solution.

Each child requires a personalised strategy.

Is Orthokeratology Safe?

When properly fitted and monitored, Orthokeratology is considered safe.

Like all contact lens treatments, success depends on good hygiene.

At The Eye Clinic, we place particular emphasis on:

• Eyelid hygiene

• Clean eyelashes

• Proper lens care

• Safe insertion and removal techniques

• Regular follow-up visits

Many contact lens complications can be prevented through proper hygiene and education.

What Happens During An Orthokeratology Consultation?

Step 1: Comprehensive Eye Examination

We assess your child's prescription, eye health and suitability for treatment.

Step 2: Corneal Mapping

Advanced measurements of the eye are performed.

Step 3: Trial And Fitting

Your child can experience handling and wearing the lenses before proceeding.

Step 4: Lens Ordering

Custom-designed lenses are manufactured for your child's eyes.

Step 5: Follow-Up Monitoring

Regular reviews ensure:

• Good lens fit

• Healthy eyes

• Effective myopia control

• Stable vision

Lifestyle Habits That Help Myopia Control

Orthokeratology works best when combined with healthy visual habits.

We encourage:

• One hour outdoor time minimum

• 20 minute near activities 

• 20 minutes break for far activities  

• Good reading posture

• 3 monthly eye check 

These habits support overall eye health and may reduce the risk of myopia progression.

Frequently Asked Questions

What age can a child start Ortho-K?

Many children can begin from approximately 6 years old if they are mature enough to manage lens wear with parental support.

Does Ortho-K permanently cure myopia?

No. Orthokeratology temporarily reshapes the cornea. The effect reverses if the lenses are discontinued.

Is Ortho-K painful?

Most children adapt quickly and become comfortable within a short period.

Can my child play sports?

Yes. This is one of the biggest advantages of Orthokeratology. Children enjoy clear vision without daytime glasses.

How long do OK lenses last?

Most lenses are replaced approximately once a year, depending on wear and condition.

When Should Parents Consider Orthokeratology?

If your child's prescription is increasing every year, it is worth discussing myopia control options early.

Waiting until myopia becomes severe may mean missing the opportunity to slow progression during the years when eye growth is most rapid.

Early intervention often produces the best long-term results.
