Parents often ask whether orthokeratology (Ortho-K) is safe for children.
Ortho-K has been used for many years and is considered safe when properly prescribed and monitored by an eye care professional.

How Ortho-K Works
Ortho-K lenses are custom-designed contact lenses that are worn overnight while sleeping.
These lenses gently reshape the front surface of the eye so that light focuses correctly on the retina. In the morning, the lenses are removed and many patients are able to see clearly during the day without glasses or contact lenses.
Why Ortho-K Is Used for Myopia Management
In addition to providing clear daytime vision, orthokeratology has been shown to help slow the progression of myopia in many children.
Slowing myopia progression is important because higher levels of myopia are associated with increased risks of certain eye conditions later in life.
Monitoring Treatment Effectiveness
A key part of safe and effective Ortho-K treatment is regular follow-up care.
At Northern Optics, we also use axial length monitoring to track eye growth over time. This allows us to evaluate whether myopia progression is slowing and adjust treatment if necessary.
With proper care and monitoring, orthokeratology can be a safe and effective option for managing myopia in children.
