#1. What is Ortho-K?
Specially designed eye lenses that you can wear even when you are sleeping, allow you to see clearly next morning when you wake up after removing them. These are gas permeable which gently reshapes the front surface of your eye called the cornea.
Any progression in myopia during childhood can be slowed down with it. Any refractive error like nearsightedness, hyperopia or presbyopia can also be corrected with this.
#2. How long does the effects of Ortho-K last?
If you wear the ortho-k lenses for one night, you can see clearly for a day or two. So, it is recommended to wear them every night for achieving great results.
#3. What is Corneal Reflective Therapy?
Similar to Ortho-K, Corneal Reflective Therapy (CRT) is used for similar purposes. Generally, your eye specialist prescribes which therapy is suitable for you depending upon the issues related to your eyes.
#4. Which vision problem is treated by Orthokeratology?
Myopia also known as nearsightedness is generally treated with Ortho-K. Lesser degrees of presbyopia, astigmatism as well as hyperopia can also be treated effectively with Orthokeratology. However, this treatment differs from case-to-case depending upon the severity of the problem.
#5. Who should go for Ortho-K?
Any one suffering from mild to moderate myopia can opt for Ortho-k. However, you should know that the corneal reshaping is temporary and prone to some risks. The wearer can stop using the lenses at any point and can get back to their normal contact lenses or eye glasses.
Children and young ones who cannot go with LASIK treatments due to their low age can also opt for Ortho-K. Also, those of you who work in dusty environments which are not appropriate for wearing contact lenses can ideally choose the Ortho-k treatment.
#6. What are the expected results from Ortho-K?
Although the eye practitioners claim a result of 20/20, the acceptable result of Ortho-K treatment is 20/40 which is legally defined as well. Clinical studies reveal that the FDA approved lenses yield 20/40 or better results for 95% or more.
#7. When can you start with Orthokeratology?
Corneal Topographer is an instrument which is used by the eye specialists to measure the curvature of your cornea. It is a painless procedure and efficiently produces the map of your eye surface in less than a minute. To reach a desired prescription, you may be required to use a series of lenses, but mostly three pair of lenses helps in attaining the maximum vision correction effect. Initially, you might not be at your ease when you start using such lenses when you are asleep. But gradually you will become comfortable from the moment of its insertion in your eyes.

#8. How much time does it take to achieve the maximum result of Ortho-K?
There are various factors which influence the time taken for achieving the maximum results of Ortho-K. The intensity of nearsightedness is the key among all. Few people may observe an excellent vision just in 2-3 days.
Ortho-K is not free from side effects. So, you should take an informed decision after taking into account all the considerations. For the treatment of Ortho-K, FDA approved highly breathable GP lenses should only be used. There are many renowned brands in the market which offer such lenses of high quality.
