CRT & Ortho-K

CRT and Ortho-K Treatment at True Eye Experts
Eyeglasses and traditional contact lenses are proven to correct nearsightedness, farsightedness, and other visual problems. Some people will always seek the freedom & convenience of wearing no corrective lenses of any kind during their daily activities. While many are willing to go ahead with long-term solutions such as laser surgery, others would prefer a less invasive, more reversible answer. There is a solution to this known as corneal refractive therapy or CRT — overnight reshaping lenses fit and dispensed at True Eye Experts in Florida.


What is Involved in CRT Treatment?
The idea for CRT stems from the late 1950s when eye doctors noticed those nearsighted patients who wore hard contact lenses sometimes experience a temporary improvement in their unaided eyesight. That’s because the shape of the cornea plays a critical role in how light is refracted and how images are delivered to the retina. An abnormally-shaped cornea can cause myopia (nearsightedness), hyperopia (farsightedness) or astigmatism. But the cornea is also malleable — it can conform to a new shape for a short period of time. This discovery led to the development of corneal refractive therapy, also known as orthokeratology or Ortho-K.
CRT involves the use of specially designed contacts that you wear to bed at night. As you sleep, the lenses apply just enough gentle pressure to reshape your corneas into your ideal vision prescription. Upon awakening, simply remove the lenses and enjoy the entire day with clear vision without glasses or contact lenses. The effect can sometimes last for days at a time — because the CRT lenses are worn overnight, you can achieve uninterrupted vision correction with them. The fact that the effect is temporary means that you can always change your mind and take up glasses or traditional contacts whenever you feel like it. Many patients regard this flexibility as a great advantage over refractive correction surgery.

Is CRT Treatment Right For Me?
No single form of vision correction is equally right for everyone, and that goes for CRT as well. It is especially effective for children with mild to moderate nearsightedness, but it can also work for adults too. CRT is a viable solution for some cases of farsightedness or astigmatism. Severe cases of nearsightedness, farsightedness, or astigmatism may not be fully correctable with CRT, will be happy to provide you with other options for the best possible eyesight (which, after all, is the primary goal). CRT is an ideal solution for individuals who play sports or participate in other activities that make wearing lenses impractical. They may even help slow the progression of myopia in younger patients, which might mean that CRT is an amazing choice for your kids.
