Ortho K Lenses Can Decrease Progression Of Myopia/Nearsightedness
What Is Orthokeratology?
Utilizing Ortho K lenses, Orthokeratology (ortho-k) is the process of wearing a customized gas permeable contact lens only at night (while sleeping). Orhto k lenses gently reshape the front surface of the eye, known as the cornea. In the morning, after the user removes the lenses, they are able to see clearly for most of the day.
With very early orthokeratology dating back to the 1960’s, this treatment has been given various names over the years:
- Ortho K lenses or OK Lenses
- Overnight contact lenses
- Corneal Refractive Therapy (CRT)
- Corneal reshaping contact lenses
- Gentle Shaping System
- Corneal Moulding
- Wave Front Corneal Moulding
With advances in technology, most OK lens users today find they are able to see properly without prescription glasses or contact lenses for one to two days after sleeping with the Ortho K lenses.

When Is Ortho K Prescribed?
The fitting of OK lenses is usually prescribed for the following:
- To slow the progression of myopia (nearsightedness) in children and teenagers.
- To correct refractive errors in adults and children such as myopia/nearsightedness and astigmatism.
OK lenses are an excellent option for children who are experiencing a progression of myopia/nearsightedness. Adults and children are good candidates for these types of lenses if they:
- Are physically active with sports
- Do not want to wear glasses during the day
- Are unable to wear contact lenses
- Or are not ready for more permanent Laser Eye Surgery
Do OK Lenses For Myopia Actually Work?
The result of orthokeratology will depend on your prescription, age, and treatment goals. Younger eyes mould faster, therefore children and teenagers can often achieve results in just a couple nights. Adults with higher prescriptions will typically take longer.
In many patients, orthokeratology can temporarily correct nearsightedness of up to -6.00 diopters of myopia. In order to maintain the results, you will need to continue using Ortho K lenses. When you stop wearing these lenses at night your vision will return to its original baseline.
During your initial orthokeratology evaluation, our Unionville Optometrists will discuss the potential outcome of your specific treatment plan.
What Should I Expect At My OK Lens Assessment & Am I A Candidate?
Patients will have a full eye exam with one of our doctors as well as imaging and measurement of corneal curvature to establish candidacy. Once confirmed, these diagnostic tests combined with a topographical map of the ocular surface, will generate custom Ortho K lenses specific to each patient.
Typically, patients will return for a second visit and spend time with our staff learning how to insert and remove their Ortho K lenses. This typically takes two to three 20-minute sessions and/or until patients are comfortable handling the Ortho-k lenses themselves.
Patients will be seen for follow-up appointments where refraction and imaging takes place to ensure optimal fit and vision.
