Left is soft contact lens. Right is Ortho-K lens.
Ortho-K lenses are specially designed contact lenses worn overnight to gently reshape the cornea. By morning, your child can enjoy clear, natural vision all day without the need for glasses or contact lenses. OrthoK is an innovative, non-surgical solution particularly effective for managing myopia (nearsightedness) in children.
The ortho-k lenses are worn at night to reshape the front surface of the eye while you sleep. Vision improvements are reversible but can be maintained if you keep wearing the lenses as directed.
The lenses work by flattening the center of the cornea, changing how light is bent as it enters the eye. Most Ortho-K lenses are worn overnight to flatten the cornea, then removed during the day. These overnight lenses are rigid, gas-permeable lenses that are sturdy enough to reshape the cornea, but also allow oxygen through so your eye stays healthy.
When ortho-k lenses are removed, the cornea stays flattened for a while and vision is corrected without the need for glasses. If you stop wearing the lenses at night, your eyes will eventually go back to their original shape and the refractive error will return. You have to keep wearing the lenses regularly to keep the vision correction.
Research indicates that children who wear Ortho-K lenses show a 30-50% reduction in myopia progression compared to those who wear regular eyeglasses or contact lenses. This reduction is achieved by temporarily reshaping the cornea overnight, resulting in clear vision during the day and minimizing the eye’s tendency to grow longer, which is a primary cause of worsening myopia.
Orthok lenses are not typical contact lenses that you can buy from a shop and whether it is good has nothing to do with the brand.
Every pair of orthok lenses needs to expertly fitted in order for treatment to take effect. We will map and measure the surface of your cornea using an instrument called a corneal topographer and then design a lens especially for your eye. The cornea map is created by reflecting light off the surface of the eye. The machine doesn’t touch your eye, and there is no pain. The corneal topography map shows the shape and curves of your cornea.
