CRT® Brand Contact lenses are therapeutic contact lenses that correct nearsightedness by gently and safely reshaping the cornea while you sleep. Referred to as “Corneal Refractive Therapy (CRT)” or “Orthokeratology,” CRT is a safe, non-surgical and non-invasive procedure that temporarily corrects nearsightedness, up to -6.00 diopters, and mild to moderate amounts of astigmatism.
How does CRT work?
When worn overnight, CRT® Brand Contact Lenses gently and safely flatten the front surface of the cornea, resulting in a corneal shape that focuses light correctly onto the retina. When removed in the morning, distant objects will be back into focus.
The CRT effect occurs in the corneal epithelium, which is the top layer of the cornea. The treatment is specifically designed to alter the shape of this tissue and as a result, it corrects your vision.
What are the benefits of CRT for children and younger adults?
Children and younger adults will show a significant slowdown in the progression of myopia (nearsightedness) and, in most cases, may also reduce the risk of developing eye diseases later in life, such as Glaucoma, Cataracts, and Macular Degeneration. In addition to these benefits, the patient will have no need for optical correction during daytime hours.
Because CRT is a non-surgical and reversible option, in cases when the patient has a lack of adaptation, the patient can simply discontinue use of the lenses.
