What is Orthokeratology
Orthokeratology - also know as Ortho-K - can help lower the chances of nearsightedness from getting worse. It can also correct your vision so that you don’t have to wear glasses or contact lenses during the day!
Is there a difference between ortho-k for myopia correction & ortho-k for myopia control
There's a big difference! Myopia correction, which is when an optometrist prescribes ordinary distance glasses to help your child see clearer, is only temporarily masking the condition by fixing the symptoms — blurred vision. What we do is treat the underlying condition that causes the blurred vision — abnormal eye growth and elongation — so that further vision deterioration can be prevented.

Slows down nearsightedness from getting worse
Ortho-K treatment can significantly slow down, and sometimes even halt, their eyes from further worsening that ordinary glasses and contact lenses cannot.
It is also great for kids who do not like to wear their glasses or those with active lifestyles. After wearing these lenses at night, the patient will not need to wear glasses or contact lenses during the day!

safe and reversible alternative to LASIK surgery
If you're worried about the risks of laser eye surgery, or your eyes aren't suitable or stabilized yet for LASIK, Ortho-K could just be the vision solution you need. With Ortho-K technology you can be glasses and contacts-free during your day. Restore your vision as you sleep.


How does Ortho-K slow near-sightedness?
With Ortho-K vision technology, fully customized contact lenses are made to fit the exact shape of your eyes. As you sleep, your eyelid and the lens place gentle pressure on your cornea, the clear front surface of your eye, molding its shape by a precise, pre-determined treatment amount calculated using sophisticated 3D modeling of your eye shape. Our corneal topographer precisely measures individual points on your cornea, as unique as your fingerprint, to assist us in designing Ortho-K lenses that are uniquely yours.
To understand how Ortho-K lenses work to reduce your child's myopia progression, it's important to first understand the concept of hyperopic defocus. With regular glasses and contact lenses, light is not focused uniformly across the entire surface of the retina, the light-sensing cells at the back of the eye. While central straight ahead vision is clear, peripheral light rays are focused beyond the plane of the retina instead of on it, which causes blur for that particular part of the eye. This is termed hyperopic defocus. This defocus in the peripheral retina is a stimulus for the eye to grow longer in a growing child or adolescent. When the eye grows in length, in a process called axial elongation, the eye becomes more myopic and leads to an increase in the child's short-sightedness prescription. This eye growth also leads to increased eye health risks.
Ortho-K lens treatment effectively refocuses peripheral light rays from beyond the retina to the surface of the retina, reducing the hyperopic defocus and peripheral blur, which in turn reduces the growth signal and slows axial elongation of the eyeball. How an Ortho-K lens achieves this is by creating a circular 'multifocal' shape effect on the surface of the eye, the cornea. When Ortho-K restores vision by flattening the central zone of the cornea, a redistribution of cells causes the peripheral areas of the cornea to become thicker. The thickened peripheral cornea bends light more, reducing the hyperopic peripheral defocus. So Ortho-K treatment for children simultaneously achieve two objectives: (1) Correction of their blurred distance vision, and (2) Reduces myopia progression and eye growth.
