Ortho-K is a type of contact lens that is worn overnight while you sleep. It is made to temporarily reshape your cornea, so that when you wake up and take out the lenses, your vision will be corrected for the day. While it is not a permanent solution, it can offer significant relief from myopia, or nearsightedness. In some cases, it may even be possible to avoid progressive myopia, or the worsening of your vision over time.
If you are considering ortho-k to treat your myopia, it is important to consult with an eye doctor to see if you are a good candidate for the procedure. There are a few factors that may make you ineligible, such as having certain eye conditions or taking certain medications. Once you have been cleared for ortho-k, your eye doctor will take measurements of your eyes and create a custom set of contact lenses for you.
You will need to wear these lenses every night, for at least 8 hours, in order to achieve the desired effect. Over time, you may need to have your lenses replaced or adjusted, as your eyes may change shape. However, with proper care and maintenance, ortho-k can offer a safe and effective way to improve your vision.

Is ortho k permanent?
Ortho-K is a type of contact lens that is meant to be worn for a specific amount of time, typically overnight, in order to gently reshape the front surface of the eye (cornea). The goal of Ortho-K is to reduce or eliminate the patient’s dependence on vision correction devices such as glasses or daytime contact lenses. In most cases, the effects of Ortho-K are temporary and the patient will need to continue to wear the lenses nightly in order to maintain their good vision. However, there are some patients for whom the Ortho-K treatment may be considered “permanent” in the sense that they may only need to wear the lenses on a occasional basis, or not at all, once their vision has stabilized. This is typically true for young children who are still growing and whose corneas are still changing shape. For these patients, once their corneas have reached a certain point of stability, they may no longer need to wear the Ortho-K lenses at all. It is important to note, however, that even in these cases, the child’s vision could still change over time and they may need to revisit Ortho-K treatments later on in life.

How long does ortho k last?
Orthokeratology, or ortho-k, is a type of corrective lens that is worn overnight. The lenses gently reshape the cornea, the front surface of the eye, while you sleep. This enables you to see clearly during the day without wearing contacts or glasses.
The duration of ortho-k's effect varies from person to person, but generally lasts for one to two years. Once the desired level of vision correction is achieved, the lenses can be worn as needed to maintain that level of vision.
Ortho-k is an effective and safe alternative to LASIK surgery for those who are not suitable candidates or who are not ready for such a permanent solution. It is also a good choice for people who play sports or work in occupations where glasses or contacts can be a hindrance.
If you are considering ortho-k, be sure to consult with an experienced and reputable eye care professional to find out if it is right for you.

How often do I need to wear ortho k?
Assuming you are asking about Orthokeratology, or Ortho-K, the frequency of wear depends on the specific brand of lenses and the person's individual corneal shape. In general, Ortho-K lenses are worn overnight and then removed during the day. The lenses reform the cornea so that the patient can see clearly during the day without lenses or glasses.
Ortho-K is usually a temporary adjustment and most people will eventually need to wear glasses or lenses during the day as their vision changes. However, people with certain corneal shapes may be able to maintain their results with only periodic overnight Ortho-K lens wear.
What are the side effects of ortho k?
There are a number of potential side effects that can occur when using ortho k. These can include:
- blurred vision - dry eyes - eye irritation - headaches - nausea
All of these potential side effects are generally mild and temporary. In rare cases, more severe side effects can occur, such as:
- corneal injury - excessive Consumer Reports findings include side effects such as "corneal deposits," "decreased vision quality," and " worsened myopia." However, the study also found that "most people who use Ortho-K experience little to no adverse effects."
Can I still wear contacts or glasses with ortho k?
Ortho-K is a type of vision correction that uses special contact lenses to gently reshape your cornea overnight. This temporary change in your cornea’s shape allows you to see clearly during the day without glasses or contacts.
Ortho-K is safe and effective for all ages, including children. The lenses are FDA-approved and have been used for over 25 years to correct vision.
Ortho-K can be used to treat nearsightedness, farsightedness, and astigmatism. It is a good option for people who are not candidates for LASIK surgery or who don’t want to undergo surgery.
Ortho-K is not permanent and you will need to wear the lenses every night to maintain clear vision during the day. You will need to visit your eye doctor for periodic follow-up appointments to make sure your vision is still corrected and to check the health of your eyes.
If you stop wearing the lenses, your vision will gradually return to its pre-treatment state.
What happens if I stop wearing ortho k?
If you stop wearing ortho k, your myopia will gradually return. Within 6 to 12 months, you will likely be back to your original eyeglass prescription or even slightly worse. Wearing ortho k is a lifetime commitment to maintaining good vision.
Frequently Asked Questions
What is ortho-k (orthokeratology)?
Ortho-k (orthokeratology) is the fitting of specially designed gas permeable contact lenses that 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. What are ortho-k lenses used for? Ortho-k contact lenses are often prescribed by an eye doctor to decrease dependency on eyeglasses or sunglasses and provide a more comfortable vision experience. Additionally, ortho-k contact lenses may be prescribed for patients with keratoconus, astigmatism, and other refractive errors who experience significant pain and discomfort from wearing glasses or sunglasses. The gas permeable contact lens material allows for a gradual release of pressure over a period of eight hours so the cornea does not stretch excessively during sleep. Ortho-k lenses are also frequently prescribed to improve night vision and reduce fatigue
What are the benefits of ortho-k?
- Safe, comfortable and effective vision correction. Ortho-k lenses gently reshape the curvature of the eye overnight. The cornea plays a key role in creating a sharp, optical focus. Upon waking, the slight change in cornea curvature is enough to create clear, sharp vision for the duration of the day. - Reduced potential for keratoconus and other forms of corneal ectasia. Ortho-k lenses offer effective plumping to help protect your delicate cornea from further deterioration and thus decrease your chances of developing keratoconus or other types of corneal ectasia. - Improved vision during evenings and at night due to reduced stress on the eyesight muscles caused by morning sunlight glare. Unlike regular glasses or contact lenses which require you to constantly adjust their position, ortho-k lenses stay in place throughout the day and into the evening hours, allowing you more restful sleep. Who is best suited for orth
Can Ortho-K lenses be used with other lenses?
Yes, Ortho-K lenses can be safely and successfully performed with other gas permeable (GP) lenses and corneal reshaping fitting techniques. However, please consult with your eye doctor to ensure the best fit for your individual needs.
What is ortho-k treatment for myopia?
Ortho-k treatment is a procedure that uses special contact lenses to temporarily change the curvature and shape of your cornea. Ortho-k treatment can improve your myopia by correcting the eye's natural spherical shape.
What is orthokeratology and CRT?
Orthokeratology is a treatment used to reshape the curvature of the cornea. CRT is an acronym for cyclic refractive therapy, and it uses small bursts of light energy to alter the shape of the eye lens. These treatments can be used together or separately.
