Corneal Reshaping Technique in Amarillo, TX
Corneal Reshaping Technique – also known as CRT - is a pioneering optical solution that is designed to reshape the cornea so that patients who have refractive eye errors are not dependent on prescription lenses for them to see clearly. You may also hear the corneal reshaping technique referred to as orthokeratology, or ortho-k for short.
We are proud to be able to offer corneal reshaping, carried out by our expert optometry team at our offices here in Amarillo, TX.
How does corneal reshaping technique work?
Corneal reshaping is primarily recommended for patients who have been diagnosed with myopia (near-sightedness) although it can also be used to address hyperopia (far-sightedness) and astigmatism. In patients with myopia, their cornea (the transparent dome that covers the front part of the eye) is too steep to refract light correctly onto the retina, which is the small area of light-sensitive cells at the back of the eye. The retina is responsible for receiving the refracted light and turning it into a neurological message which is then passed up the optic nerve to the brain so that we can identify what we see. When the cornea is too steep, the light is refracted in front of the retina rather than directly onto it, causing the image that we see to appear blurred.
Corneal reshaping technique is a therapeutic process, the goal of which is to reshape and flatten the cornea. This is done using bespoke contact lenses which have been designed specifically for the patient’s eyes. These lenses are made from gas-permeable materials that enable sufficient oxygen to penetrate through them and reach the eyes, keeping them comfortable and healthy whilst the lenses are being worn.
Whilst ordinary lenses shouldn’t be worn overnight, the material used to create corneal reshaping lenses mean that it is perfectly safe to wear them whilst you sleep. When in place, they apply gentle force to the cornea to direct it into a more domed appearance. In doing so, light can then be refracted correctly, and the patient can see clearly. When you wake up the next morning, you can remove your corneal reshaping lenses and your corneas should stay in their new position for a number of hours before returning to normal. Corneal lenses should be worn overnight for optimal results. Studies have shown that if you wear them consistently, you will be able to enjoy clear vision without dependence on prescription eyewear for an entire 18-hour day at a time.
Corneal reshaping technique for slowing myopia progression
Research has shown that not only is the corneal reshaping technique effective in treating myopia and eliminating patient dependency, but it can also slow the progression of the condition, particularly in childhood. This is important because controlling myopia early on may prevent your child from developing high levels of near-sightedness that will necessitate them needing thick, corrective lenses in glasses frames in the future. It could also reduce their risk of developing serious eye problems such as cataracts, glaucoma or a detached retina in the future.
What happens if I want to stop treatment?
The effects of corneal reshaping last only as long as the treatment does. If you choose to stop wearing your corneal reshaping lenses, within a few days, the shape of your cornea will have returned back to its original position and your eyesight will also return to what it was before. This gives patients the option to consider alternative treatments for their myopia should they so wish.
