Axial Length monitor of myopia control with IOL Master®
Axial Length monitor of myopia control with IOL Master®
AOK Accelerated Orthokeratology Eye Braces
has been well studied to give
between 35 to 85% myopia control.
AOK lens design is critical in the amount of myopia control. The more myopic peripheral defocus, the more efficacious.
Our doctor's experience in lens design & expertise will allow your child to get the most optimal myopia management, getting good stable vision & in the safest, healthiest way possible.
Dr Albert Ng, OD, FAAO, FIOMC, has been managing myopia with AOK Eye Braces for more than 30 years, including his own children.
The benefits of overnight AOK Eye Braces include that there is no lenses needed to be worn during daytime with excellent myopia control. Thus, it is more comfortable & convenient in many activities.
It also has been FDA approved for overnight wear. Many studies has confirmed it's efficacy & safety in young children. Studies have shown children 8-12 years old are safer contact lens wearers than teens & adults, with a lower rate of infection.

Axial length measurement
using the IOL Master® optical biometer is the most accurate method to monitor the effectiveness of your child's
myopia control treatment.
Increase in axial length means Increase in Myopia.
The IOL Master® optical biometer is more accurate & easier to do on children compared to ultrasound methods of axial length measurement.
Axial length elongation is recognized by the medical research community as the gold standard for monitoring myopia progression.
Annual Axial Length measurements is critical
because :
• A longer eye have
(1) a higher risk of myopia progression
(2) a higher risk of myopic disease
• Risk of eye disease increases exponentially for axial length > 26.0 mm
• More accurate than measuring power of your lens Rx to monitor the myopia control efficacy of your treatment.
Atropine Rx drops 35-50%

multifocal contact lenses & multifocal glasses 30-52%
In our Atropine Myopia Control Program,
our doctors will monitor the effectiveness of different dosages of atropine for your child with axial length measurements using the
IOL Master® .
Measurement of axial length elongation is recognized as the gold standard of monitoring myopia control treatment efficacy.
Compounded low dose atropine prescription eye drops reduce progression by 35 to 50%.
Atropine combined with AOK Eye Braces & other optical peripheral defocus therapy has shown to give additionally 5-10% more myopia control.
Different children respond differently in efficacy & side effects. The higher the dosage, the more efficacious but the more potential side effects.
Our doctors will evaluate which is the
optimal dosage for your child.
We will add adjunct myopia control therapy such as AOK Eye Braces, multifocal contact lenses or peripheral defocus spectacles if atropine therapy alone is not sufficient or when your child is ready for other myopia control therapy.
multifocal contact lenses & multifocal glasses 30-52%
multifocal contact lenses & multifocal glasses 30-52%
multifocal contact lenses & multifocal glasses 30-52%
Multifocal contact lenses & Peripheral Defocus Glasses
has shown to be effective between
30 to 52% myopia control.
They are now available in RGP or daily & monthly disposable soft contact lenses.
Our doctors can evaluate whether if daytime multifocal lenses or Day Eye Braces are suitable for you.
Peripheral Defocus glasses in the new DIMS lens technology is also promising.
Presently, only MiSight® daily soft multifocal contact lenses are FDA approved for myopia control. All other modalities including AOK, low dose atropine, peripheral defocus spectacles are used for myopia control in an "Off Label" basis.
outdoor time
multifocal contact lenses & multifocal glasses 30-52%
reduce screen time
Outdoor time
has been shown in many studies in slowing myopia progression for Pre-Myopes,
before your child is myopic.
Doctors believe that only the very bright ambient light outdoors is useful in myopia control. Bright light indoor does not seem to have the same therapeutic effect. It may also be due to increased Vitamin D or less near work & screen time.
It is not due to looking at "green plants"
or from Blue Light as some myths tell us.
reduce screen time
multifocal contact lenses & multifocal glasses 30-52%
reduce screen time
Any screen time is bad for us.
Minimize any unnecessary phone, iPad & computer usage other than for school or work.
- It is making us more myopic, even in adulthood.
- Digital Device Addiction is prevalent in both kids & adults.
- Socially, we no longer talk to each other. We spend more time on our phones than to interact with others.
- Physically, many of us are not taking time to exercise but on our devices.
AOK Eye Brace 箍眼 近視控制
conventional glasses & contact lenses increase myopia
Research now clearly show conventional glasses & contact lenses causes hyperopic defocus on the peropheral retina. This induces elongation of the eye which cause myopia to progress.
AOK Eye Brace
AOK (Accelerated orthokeratology or Ortho-K) is the fitting of specially designed high oxygen gas permeable contact lenses that you wear overnight.
While you are asleep, the lenses gently reshape the front surface of your eye (cornea) by gentle tear pressure that causes the migration of the corneal epithelial cells. When you remove the lenses when you wake up, you are able to see clearly.
Clinical Studies confirms safety & efficacy of Myopia Control
In 2016, Dr M Liu PhD, University of California, Berkley and Dr Xie, MD, PhD, Peking University publishes a major Review of 170 clinical studies that summarized the safety of orthoK.
"Conclusions: There is sufficient evidence to suggest that
OrthoK is a safe option for myopia correction and retardation.
Long-term success of OrthoK treatment requires a combination of
1) proper lens fitting,
2) rigorous compliance to lens care regimen,
3) good adherence to routine follow-ups, and
4) timely treatment of complications."

multiple research on AOK safety & efficacy
Since 1990,
there has be an exponential number of studies
overwhelmingly confirming
both the
efficacy & safety of AOK
for myopia control
in children
FDA approval since June 2002
Dr George Jessen created one of the earliest orthokeratology contact lens in the 1960s which he marketed as "Orthofocus" contact lens. In the 1990s, computerized corneal topography & high oxygen permeable lenses allowed orthokeratology becoming an overnight procedure that accelerated the cornea reshaping effect safely & effectively. Hence, AOK, Accelerated Orthokeratology.
The FDA, USA Food & Drug Administration, approved the first orthokeratology lens design for overnight wear made by Paragon Science
in June , 2002.
