Corneal Refractive Therapy (CRT), also known as Orthokeratology, uses therapeutic contact lenses that gently and safely reshape the cornea while you sleep to correct nearsightedness. The lenses are worn at night and removed in the morning. The result: clear vision the whole day. This process is a safe, non-surgical and non-invasive procedure that corrects myopia up to -6.00 diopters, and mild amounts of astigmatism.
Wearing CRT Contact Lenses while sleeping gives you freedom from wearing daytime contacts or glasses. This therapy offers a much more natural vision because no lens is being worn during your daytime hours.
No more dry, itchy and uncomfortable contact lenses. No hassles and interference of wearing glasses either – just great vision. Unlike refractive surgery, the process is free from surgical risk. The therapy is convenient, comfortable and can be adjusted to reflect changes in your eyesight.
