Orthokeratology, or ortho-k, involves using special gas permeable contact lenses to temporarily reshape the contour of the cornea. In this myopia control method, contacts are worn overnight and then removed in the morning. This treatment allows patients to see clearly throughout the day.
Read on to learn more about ortho-k and if your child is a good candidate for this treatment.
Ortho-k treatment usually lasts from one to two weeks. Your nearsightedness is gradually reduced as the treatment progresses. Due to the changes in your vision, you’ll need to wear disposable soft contacts during the day. After the treatment period, you can wear the ortho-k lenses at night only and see clearly during the day without the need for corrective lenses. Some patients only wear their ortho-k lenses every other night or once to twice a week to maintain a clear vision.
You’ll need to visit your optometrist regularly to make sure that your lenses are fitting properly and your eye are in good shape. It’s important to keep your lenses clean since they fit snugly on the eye as you sleep. You must clean and disinfect your lenses every time you remove them in the morning.
Is Your Child a Good Candidate?
There is evidence that ortho-k lenses can reduce existing myopia when worn during sleep. Numerous published clinical studies have also found that these lenses deter the growth of the eye’s axial length, which determines the severity of myopia.
Young individuals with progressing myopia are usually great candidates for ortho-k. Since they are more involved in sports, they can benefit from this treatment. They wouldn’t need to wear contacts or glasses when participating in physically-engaging activities.
