How Do Ortho-k Lenses Slow Myopia Progression?

Nearsightedness, or myopia, is a widespread eye disorder that primarily affects young individuals. Myopia is correctable using eyeglasses and contact lenses. However, they do not fix the underlying problem. Orthokeratology, or ortho-k, lenses are a nonsurgical and noninvasive option for slowing myopia progression in children and adults. 

What Are Ortho-k Lenses?

Ortho-k lenses, also known as corneal reshaping lenses, are a type of contact lens worn at night while sleeping. These lenses gradually reshape the cornea, the eye's transparent outer layer. The new shape allows the retina at the back of the eye to receive light with perfect focus. This results in clearer vision during the day without needing glasses or contact lenses.

How Do They Work to Slow Myopia Progression?

As ortho-k lenses correct vision, they also slow the progression of myopia, particularly in children. When the eyeball becomes too long, light focuses in front of the retina rather than on it, resulting in nearsightedness. This results in blurry distance vision.

Ortho-k lenses work by gently flattening the central cornea. This reduces the overall length of the eye. By reducing the length of the eye, the lenses slow the progression of myopia. As it is, the elongation of the eye is a critical element in the onset and progression of myopia. 

Orthokeratology lenses can assist in preventing the development of high myopia by reducing the eye's elongation. Otherwise, this condition may lead to severe eye issues such as cataracts, glaucoma, and retinal detachment.

Who Can Benefit From Ortho-k Lenses?

Ortho-k lenses can be a good option for kids and adults with myopia who want to slow its progression. They may also benefit individuals with difficulty wearing glasses or traditional contact lenses. These include athletes and people with dry eye syndrome.
 

Additionally, kids who wear ortho-k lenses may experience improved academic performance. This is owing to the fact that myopia can negatively impact academic achievement. Still, note that ortho-k lenses are not a one-size-fits-all vision correction solution. They require a customized fitting process; not all individuals may be suitable candidates. Your eye doctor can help determine if they may be a good option for you or your child.

How to Get Ortho-k Lenses

The first step is to make an appointment with an eye specialist specializing in fitting ortho-k lenses. During the appointment, the doctor will evaluate your eyes and determine whether these lenses suit you or your child.
 

If they are a good fit, the doctor will take measurements of your eyes and order custom lenses. You must wear the lenses every night while sleeping to maintain their effect on the cornea. Following the doctor's care instructions and maintenance of ortho-k lenses is essential to ensure optimal comfort and effectiveness. 

Conclusion

Ortho-k lenses are promising for slowing myopia progression in kids and adults. By gently reshaping the cornea, the lenses can reduce the elongation of the eye, a significant contributing factor to the development and progression of myopia. Schedule an appointment with an eye specialist to determine if ortho-k lenses are a good choice.
