Do you or your child have trouble seeing things far away? When you’re looking at road signs, do you sometimes find yourself squinting? Is your child’s vision changing rapidly? You or your child may have myopia, otherwise known as nearsightedness. Corneal Refractive Therapy (CRT) can help with myopia control in both children and adults alike.

What is Myopia?

  • Myopia is a common condition that researchers project to affect almost half the population in the near future. Myopia can occur when the eyeball is too long or the cornea is more curved than normal. Light rays will land in front of the retina resulting in myopic blur.
  • Most myopia progression happens at a young age. Most deal with glasses help them see clearly in the short-term. However, myopia still progresses and worsen as the child ages.

Possible Treatments for Myopia

  • There are many treatment options for people with myopia, such as:
    • Glasses
    • Contact lens
    • Corneal Refractive Therapy (CRT) 
    • Multi-focal contact lens
  • Myopia can is typically manageable with glasses and soft contact lenses. However, these methods of correction are not suitable for everyone’s lifestyle. Some people may be athletes or simply may not enjoy wearing them. For people with dry eyes, soft contact lens may be uncomfortable for continuous daily wear.
  • You may want to consider Corneal Refractive Therapy (CRT) if the following conditions listed above apply to you.

What is Corneal Refractive Therapy (CRT)?

  • Corneal refractive therapy (CRT) can be thought of as a gentle reshaping of the front surface of the cornea. CRT involves wearing a special type of contact lens that is uniquely designed to fit each patients’ eyes. 
  • It works by gently reshaping the cornea while you’re sleeping. So that, clear day time vision is possible once you remove them in the morning.

The Advantages of Corneal Refractive Therapy (CRT)

  • No need for glasses or soft contact lenses at all! Perfect for individual with active lifestyles!
  • Because CRT lenses treat your eyes while you sleep at night, you will have less of the dryness symptoms that daytime soft contact-wearers may experience.
  • More than helping you to see clearly, CRT can also help slow the progression of myopia, especially in kids. Children are more at risk for myopia progression because their eyeballs are still growing. Not only that, myopia puts you at risk for other more serious eye conditions. Thus, it is especially important to manage it early on.  

Multi-focal Lens 

  • For myopia control in children, multi-focal contact lenses are another option.
  • Unlike soft contact lenses, multi-focal lenses are blurred around the edges.This blurriness slows down eye growth thus slowing down myopia progression. Therefore, your child can correct their vision while wearing them to see during day time.
