What Is Corneal Refractive Therapy?
Orthokeratology, is also known as corneal refractive/reshaping therapy (CRT). It involves using specialty gas permeable contact lenses to reshape the surface of the eyes while one is sleeping. This process, available through Monterey Bay Eye Center, temporarily corrects one’s nearsightedness to enable a person see clearly during the day without glasses or contact lenses.
What Are Some Of The Advantages Of Corneal Refractive Therapy?
CRT is ideal for people who are involved in sports or very active. It is also a great choice for nearsighted children with progressive nearsightedness. This therapy has the potential to stop or slow the progression of nearsightedness. Additionally, it is a good option for adults with dry eyes or whose hobbies and careers make it inconvenient for them to wear glasses or contacts.
Many people have stopped wearing soft contact lenses due to discomfort. Corneal refractive therapy is a healthier alternative. It can help them see clearly throughout the day. Parents can easily monitor their children’s contact lens care and wear with CRT contact lenses. Because the lenses do not ever leave home, parents do not have to worry about the child losing them while he or she is playing. They also do not have to worry about the lens getting dirty.
Many children are embarrassed to wear glasses. That is why many parents are opting to get CRT contact lenses for their children. CRT contact lenses can help increase self-esteem because children do not have to worry about wearing glasses during the day. It is very important for children to wear protective eyewear when they are playing sports. Children who use CRT contact lenses can wear non-prescription goggles or glasses while they are playing sports. This can help parents save a lot of money.
Additionally, people who have dry eyes may notice that the problem is worsened by traditional contact lenses during the day. CRT contact lenses can be a great alternative for these patients.
Myopia And Corneal Refractive Therapy
Myopia, or nearsightedness, is becoming more common. In the 1970’s an estimate of 25% of the U.S. population is myopic between the ages of 12-54. This number has risen to ~41% in 2000’s. Fortunately, corneal reshaping have shown to have the potential to stop or slow down myopia progression.
Are CRT Contact Lenses Safe?
Yes, CRT contact lenses are very safe. Even though many types of contact lenses cannot be safely worn at night, the Food And Drug Administration has approved CRT contact lenses for overnight wear. It is estimated that there have been over one million CRT contact lenses sold. Only three adverse events have been reported so far. All of those problems have been resolved. Corneal reshaping has been proven to be both effective and safe.
Are CRT Contact Lenses New? Why Haven’t I Heard About Corneal Reshaping Before?
CRT was first approved by the Food And Drug Administration back in 2002. CRT is considered a specialty as it requires professional certification for eye doctors to fit these lenses. Therefore, not many eye care offices offer this treatment option for nearsightedness. However, with the rise in myopia, CRT is gaining popularity.
