CRT/Ortho-K

CRT stands for corneal refractive therapy (also known previously as Orthokeratology). These custom-fitted, gentle vision shaping contact lenses are worn while your child sleeps to temporarily reshape the cornea to improve vision during the day. Your child will be able to see clearly without the need for eyeglasses or contact lenses! This method has been proven to be the most effective way to slow down myopia progression and works best with children whose vision correction is about -4.00D or less.

This method has been proven to be the most effective way to slow down myopia progression and works best with children whose vision correction is about -4.00D or less. We now have new lenses available that can help children with higher amounts of myopia (over -4.00D) and astigmatism (over 1.00D). A landmark study by the NIH (national institute of health) has shown the clinical effectiveness and safety of orthokeratology lenses over a 12 year period.
