Exploring Myopia Control with Orthokeratology

What is Myopia?

Myopia, commonly known as nearsightedness, is a prevalent eye condition that affects a significant portion of the global population1. While corrective lenses such as glasses and contact lenses provide immediate relief, they do not address the underlying progression of myopia. Orthokeratology, also known as ortho-k or overnight vision correction, has emerged as a promising non-surgical method for myopia control. In this article, we will delve into the concept of orthokeratology and its effectiveness in managing myopia progression.

Understanding Myopia Control with Orthokeratology

Orthokeratology involves the use of specially designed gas-permeable contact lenses that are worn overnight. These lenses reshape the cornea while the wearer sleeps, temporarily correcting the refractive error and allowing for clear vision during the day. However, the benefits of ortho-k extend beyond immediate visual correction; research suggests that it may slow down the progression of myopia in children and adolescents2

Is Orthokeratology Safe?

Several studies have investigated the efficacy of orthokeratology in myopia control, consistently demonstrating promising results. A meta-analysis published in the journal Ophthalmology found that ortho-k significantly reduced the progression of myopia by approximately 45%3 . Moreover, long-term studies have shown that the effects of orthokeratology persist over several years, highlighting its potential as a viable myopia management strategy.

Orthokeratology’s safety profile has also been extensively evaluated. A study published in the journal Eye & Contact Lens: Science and Clinical Practice reported that adverse events associated with ortho-k were generally mild and transient, with no serious complications observed4. Nonetheless, it is crucial for individuals considering orthokeratology to undergo thorough assessments and receive guidance from qualified eye care professionals.

Importance of Early Intervention

Early intervention plays a pivotal role in myopia control with orthokeratology. Research suggests that initiating ortho-k treatment during childhood or adolescence, when myopia typically progresses rapidly, may yield the most significant benefits. Timely intervention can potentially mitigate the risk of developing high levels of myopia, which are associated with an increased likelihood of ocular pathologies later in life, such as retinal detachment, glaucoma, and myopic maculopathy5.

Orthokeratology for Myopia Control

Orthokeratology offers a promising approach to myopia control, providing both visual correction and the potential to slow down the progression of myopia. While it is not a permanent cure, ortho-k can provide a valuable means of managing myopia in children and adolescents, potentially reducing the risks associated with high myopia later in life. If you or your child have myopia, consult with an experienced eye care professional to determine the suitability of orthokeratology and embark on a journey toward clearer vision and long-term eye health.
