What is Ortho-K?
- Ortho-K is a specially fit pair of gas-permeable lenses that you would only wear at night. While you sleep, the lenses will gently reshape the surface of your cornea. When you wake up in the morning, you will be able to see clearly without the need for glasses or contacts.
Are the Effects Of Ortho-K Permanent?
The effects of Ortho-K are not permanent. This is why the lenses need to be worn every night. If you go 72-hours without wearing the lenses, your vision will go back to its original state.
Why Are the Ortho-K Lenses Prescribed?
There are two main reasons that these lenses are prescribed.
1) Correction of refractive errors: These lenses are most commonly used to treat shortsighted and astigmatism.
2) Slow the progression of childhood myopia: Over the last several years, these lenses have been used in children 5 to 12 years old. They have shown great success is slowing the progression of myopia in children.
What to Expect When Being Fit With Ortho-K
- To start treatment with Ortho-K, you will need a special contact lens fitting. First, your optometrist would measure the curvature of your cornea. It is a painless procedure that creates a topographical map of the surface of your eye. This test takes just a minute. You may need to wear a series of temporary lenses until you reach your prescription. This is normal.
How Long Does It Take For Ortho-K To Reach Its Maximum Effect?
- The length of time before you reach your best vision with Ortho-K depends on the strength of your prescription. For lower prescriptions, it can take just a night or two. For stronger prescriptions, it can take up to two weeks for maximum correction.
Does The Treatment Hurt?
- When you start the Ortho-K treatment, you will likely feel them in your eyes until you fall asleep It isn't pain, it is awareness. After you have been wearing them for some time, you won't feel them in your eyes any longer.
