How Does Orthokeratology Help Slow Myopia Progression?

Myopia or nearsightedness is a common eye problem where distant objects appear blurry. Apart from weak vision, myopia can lead to physical changes to the eye structure. The condition can cause the cornea to steepen, or it can lead to an increased lengthening of the eye. 

The impact of myopia on the eye tissues can result in an increased risk of developing eye diseases. Treatments like glasses or contacts can help correct myopia, but the result is temporary. The vision undergoes correction only when an individual is wearing the lenses. The options cannot prevent the progression of myopia.

Understanding Orthokeratology

Orthokeratology is a myopia treatment option that offers several benefits. The treatment, also called ortho-k, involves the use of special gas permeable lenses. The contact lenses help reshape the cornea while the patient sleeps. Ortho-k lenses need custom-fitting to suit each eye. 

This involves taking measurements of the eye and the cornea curvature to create the lenses. The lenses are custom-fitted for the unique shape of the patient’s eyes. The lenses fit perfectly over the cornea, allowing air to pass through, which helps with moistness and comfort. 

How Ortho-k Lenses Work

The patient going through orthokeratology will wear the special lenses before going to bed. One wears the lenses overnight, during which time the lenses work to reshape the cornea. In the morning, the individual removes the lenses and goes about their daily routine without glasses. 

Reshaping the cornea allows individuals to see clearly throughout the day without using their prescription eyeglasses or contacts. The clear vision will usually last all day. For best results, one must wear the ortho-k lenses every night. 

Slowing Myopia Progression

Myopia typically worsens with age. Orthokeratology works to effectively slow down the progression of myopia in children. Children and teens can benefit from slowing myopia progression. Slowing down the process can help prevent the development of high myopia. 

Children can benefit greatly from ortho-k treatment. The treatment is most effective when it begins at an early age, usually between the ages of six to eight. Patients who have pupils that are larger than average can also benefit from orthokeratology. 

Why Slow Myopia Progression?

It is vital to slow the progression of myopia because if left untreated, it can lead to serious eye problems. People with myopia have a high risk of developing eye conditions such as glaucoma, cataracts, retinal detachment, and macular degeneration. 

Pediatric eye doctors recommend starting treatment as soon as possible if your child has signs of being myopic. Kids need to have a clear vision to ensure they have an optimal learning experience. 

Effectiveness of Orthokeratology

Ortho-k is proving to be very effective for myopia control. Orthokeratology lenses help flatten the central cornea while causing the mid-peripheral cornea to steepen. Reshaping the cornea helps reduce myopia. 

The treatment is effective, and it eliminates the need to wear corrective lenses throughout the day. The earlier the treatment begins, the more effective it is. The degree of myopia varies in individuals. The goal of treatment is to keep myopia from progressing to a high level. If your child shows signs of being nearsighted, it is a good idea to talk to an eye doctor about orthokeratology.
