THE SCIENCE BEHIND CRT
Ortho-K (short for Orthokeratology) is a non-surgical solution for patients with myopia (nearsightedness) that uses specially designed contact lenses (like Paragon CRT® lenses) to improve vision.
When worn overnight, Paragon CRT® contact lenses gently corrects the curvature of the cornea, resulting in a corneal shape that focuses light correctly onto the retina. When removed in the morning, distant objects will come back into focus and patients can see clearly without the use of glasses or daytime contacts.
COULD CRT BE RIGHT FOR ME OR MY CHILD?
Myopia (nearsightedness) usually begins in childhood, as early as age 6. When left uncorrected, myopia can affect a child’s ability to learn and develop.
If you or your child suffers from any of the following symptoms of myopia, Paragon CRT® contact lenses might be right for you:
Blurred vision when viewing distant objects
Frequent squinting and blinking
Difficulty with nighttime driving
Needing to sit closer to the television or computer
Holding books and tablets uncomfortably close while reading
Falling behind in school
Corneal Reshaping (Orthokeratology)
Orthokeratology is a procedure for correcting myopia (nearsightedness) and mild astigmatism by gently reshaping the cornea with special contact lenses, which the patient places in his or her eyes overnight.
When successful, patients will experience clear vision during the day without contact lenses or eyeglasses. However, the results are temporary, so the patient must continue to wear the lenses regularly at night to maintain optimum results.
