Orthokeratology, also known as ortho-k, is the temporary reshaping of the cornea for better eyesight. It is accomplished with specially crafted and fitted contact lenses. The procedure is frequently compared to dental braces since it is similar to orthodontics for your eyes.
With this procedure, you may cure your refractive problem without having to undergo eye surgery. Instead, you put on breathable and firm therapeutic contact lenses at night for clearer vision in the morning. As you sleep, the gas-permeable lenses alter the shape of your cornea. The cornea can last for 24 to 36 hours after being reshaped. Although vision enhancements are temporary, they can be kept if you continue to use the lenses as instructed.
The cornea is a transparent window that is responsible for eye focusing abilities. It directs light onto the retina. It has a very elastic tissue.
Using a device known as a corneal topographer, an ophthalmologist will map and measure the surface of your cornea before creating a lens specifically for your eye. By reflecting light off the eye's surface, the cornea map is made. Your eye is not touched by the instrument, and there is no discomfort. Your optometrist can see the curves of your cornea thanks to the corneal topography map.
By flattening the cornea's center, the lenses alter how light is bent as it enters the eye. Most orthokeratology lenses are removed throughout the day after being worn overnight to flatten the cornea.
When you quit using the lenses, your cornea will return to its normal shape, which will cause your eyesight to return to where it was prior to beginning the treatment.
While ortho-k lenses may correct a variety of refractive problems, nearsightedness (myopia) is where they work the best. These lenses may be recommended by eye doctors for different types of vision conditions, including:
age-related farsightedness (presbyopia).
