Correct Nearsightedness With Ortho-K Lenses
Thirty to forty percent of adults in the United States live with nearsightedness, also known as myopia. A defect in the contour of the cornea is a major contributing factor in myopia. Ortho-k lenses are worn overnight to reshape the cornea so that you do not need vision correction during the day. Dr. Jenny Choi, our optometrist at See 20/20 Optometry in Santa Ana, CA, will help you to determine if ortho-k is the right solution for you.
What Is Nearsightedness?
The clear layer of tissue covering the pupil and iris of your eye helps to focus light onto your retina. The retina is located on the back wall of your eye and translates information contained in light into neural signals that the brain can read. The brain then translates the signals into images.
Nearsightedness occurs when the focused light falls short of the retina. This causes objects at a distance to appear blurry. This is often due to a misshapen cornea. The reshaping action of ortho-k lenses corrects this problem. Symptoms of nearsightedness include:
- • Objects appearing blurry at a distance
- • Squinting to see better
- • Headaches related to eye strain
- • Problems seeing while driving, particularly at night
How Do Ortho K Lenses Correct Nearsightedness?
Corneal reshaping therapy uses contact-like lenses to reshape the contours of the cornea. The gentle pressure they put on your cornea corrects its curvature. The lenses are worn while sleeping. After waking up, you take the lenses out and carry on with your day. Over time, the shape of your cornea will improve to the point where you will not need glasses or contacts.
To begin the process of having ortho-k lenses made for you, our optometrist will measure the size of your cornea. A topographical map of your cornea will also be created. This map allows our optometrist to determine what adjustments need to be made to your cornea's curvature. Ortho-k lenses are created to the specific measurements of your eyes to make these adjustments.
