Question 1

Any age restriction for Ortho-k?

Accepted Answer

No, both adults and children can wear Ortho-K lenses. The youngest patient we have was 6 years old, her mother worked with her every night and after 2 months, this cute girl was able to insert and remove the lenses by herself under her mom&rsquo;s supervision. Also, we have few people in their 40&rsquo;s and 50&rsquo;s who love the freedom that Ortho-K brings to them. One eye was corrected for distance vision and the other for reading, this is known as &ldquo;monovision&rdquo;.

Question 2

How quickly is my vision to improve with Ortho-K?

Accepted Answer

Your vision will improve after the first night and it will improve further and stabilise over the next two weeks of Ortho-K wear because your eye shape remodel with the treatment. For higher degrees of short-sightedness and astigmatism will take longer time to achieve optimum vision.

Question 3

What prescriptions are suitable for Ortho-K?

Accepted Answer

Ortho-K typically works best for myopia (short-sightedness) between -1.00 to -6.00. The amount of astigmatism reduction depends on the type of astigmatism and amount. The upper limits for astigmatism reduction are 1.50 diopters of &ldquo;with-the-rule&rdquo; corneal astigmatism and 0.75 diopters of &ldquo;against-the-rule&rdquo; corneal astigmatism. Ortho-K will not have an effect on the internal astigmatism.
