Parents Questions Answered Corneal Refractive Therapy

Children are becoming nearsighted at an alarming rate.
Nearsightedness, also known as myopia, is expected to impair 50% of the population by the year 2050. This increasing statistic among the younger generation have been attributed to multiple factors like the increase in technology use and decrease in outdoor activities; all have taken a toll on people’s vision.
While the numbers may seem scary, there’s something parents can do to help their children who are becoming nearsighted. Corneal Refractive Therapy can help people improve nearsightedness with the use of special contact lenses you sleep in!
What is Corneal Refractive Therapy? Corneal Refractive Therapy, also known as CRT, treats nearsightedness without daytime use of contacts or glasses. These specially designed contacts reshape the curvature of the cornea overnight. While the patient sleeps, the contacts are hard at work.
This type of treatment is also called orthokeratology, or Ortho-K for short. Ortho-K lenses provide a more active lifestyle free from glasses or daytime contacts. These overnight contact lenses gently reshape the curvature of the cornea. When they’re removed in the morning, patients will be able to see clearly.
