The world of eyecare is one of the fastest-evolving fields in medicine today. Never before have there been so many new techniques and scientific breakthroughs. Corneal Refractive Therapy (CRT) is a safe, non-surgical contact lens procedure to reduce or eliminate blurred vision caused by nearsightedness and astigmatism. It dramatically improves the natural vision. CRT was developed in 1962 and has provided corrective care to thousands of patients through this therapeutic application of contact lenses. A series of special lenses is fit in stages to gently reshape the cornea and improve vision without surgery or damage to the cornea.
|Benefits of Corneal Refractive Therapy|
basic purpose of Corneal Refractive Therapy (CRT) is to improve visual
function using custom contact lenses, shaped specifically for each patient. In people of all ages with increasingly stronger prescriptions, corneal refractive therapy
can slow down or stop the ever-increasing need to get stronger glasses. Not
everyone can presently benefit by this procedure. Yet,
for many, this is a safe, non-surgical approach to improving
and restoring vision. The doctors at Arizona's Vision will
evaluate your eyes and your vision to determine whether you are a good
candidate for corneal refractive therapy. As shown in the video below,
Arizona's Vision is a Certified Wave™ Designer, one of the advanced
technologies we use for custom contact lens fitting and as an applied
technology within CRT.

On the first day of your
procedure you should arrive at the office as rested and relaxed as possible. Expect this visit to last approximately
Results vary from
person to person, so it is not always possible to predict your exact
response to this therapy. Myopia, or nearsightedness of mild or
moderate degrees (20/200 or better), usually can be corrected to 20/20-20/30.
Higher degrees of myopia may gain dramatic improvement, allowing that person
to function without lenses. Astigmatism of moderate amounts can also be
reduced or eliminated, enhancing visual performance. With today's advanced
computerized lens design and manufacturing equipment, better and faster results
are obtained. The contact lens materials have also made technological
advances, allowing better
safety and retention.
|Rare Risks and Complications|
Your eyesight changes slightly over time, even if you do nothing to enhance
your vision. This does not mean this procedure is unstable. Many
outside factors affect vision progression, like age, eye growth in children
and close work, as well as other factors. However, in most patients, vision does
significantly with proper retainer lens wear.
