Benefits of CRT Lenses VS Laser Eye Surgery
A long time ago, back in the 1960′s, two California doctors when getting feedback from their patients who wore contact lenses, kept hearing the same type of story over and over again. Many times their patients would leave their home, drive to work and then halfway through the day notice that they were not wearing their contact lenses. And they were seeing perfectly well. It appeared that the constant wearing of the contact caused a gradual reshaping of their cornea, improving their ability to see. This chance discovery eventually led to experimentations and studies on shaping the eyes using contact lenses.
Corrective eye braces or CRT (Corneal Refractive Therapy) lenses as they are formally known, are hard contact lenses that act much like a retainer or braces do on your teeth. You put them on at night just before you go to bed. During the night, while you sleep, they reshape the cornea of your eye. When you wake up in the morning, your blurred vision is gone. You can see the pictures on your wall, the buttons on your clothes, and the alarm clock on your dresser. You have 20/20 vision.
When you have cosmetic laser eye surgery, the changes are permanent. With this method, however, it’s a bit different. The changes to the cornea will last only a day on some people. On others, it has lasted up to a week.
Vision is one of the most critical and important senses that we, as humans, possess. So it makes sense that many people are apprehensive of making any kind of permanent modification to them. In addition, the increasing number of malpractice lawsuits involving refractive surgery, and some people, especially those already mistrustful of surgical operations, start to look for other ways of improving their vision. For them, eye braces are a good compromise between permanent contact lenses and laser eye surgery.
