Orthokeratology (Ortho-K/OK lens) is the fitting of special customised gas-permeable contact lenses you wear overnight. While you are asleep, the lenses gently reshape the front surface of your eye (cornea) so you can see clearly the following day after you remove the lenses when you wake up.

Orthokeratology can be a good option for adults who want an alternative to eyeglasses, refractive surgery, and especially those who experience dry eyes with soft contact lenses

But orthokeratology lenses are not only for adults. Ortho-K lenses are widely used for myopia control in children who have progressive myopia. Many studies have also shown the effectiveness of these lenses in controlling and stabilising myopia in children. It also allows children who do not tolerate glasses well or have an active lifestyle to be glasses-free throughout the day while having myopia control present at the same time.


1. A Convenient Way to Correct Your Vision

One of the benefits of using Ortho-K is that it can correct myopia and astigmatism for children and adults. Additionally, it eliminates the need for glasses or contact lenses during the day, making it a convenient solution for clearer vision.

2. Non-Surgical Solution

With Ortho-K lenses, you don’t have to worry about surgical risk or downtime. This is a non-surgical solution to reshape your cornea, unlike LASIK where the removal of corneal tissue is involved.

3. Slows Down the Progression of Myopia

Using Ortho-K lenses can also slow down the progression of myopia in children and adults. Myopia can lead to other eye conditions, such as cataracts and glaucoma. Therefore, asking for professional advice in Singapore about the use of OK lenses for your myopia can be beneficial.

4. Reversible

Corneal reshaping with an OK lens is totally reversible, and risks are very minimal with the right care and professional reviews. Plus, you can discontinue wearing the lenses at any time, provided you are ready to put on your spectacles or contact lenses again.
