Exploring Orthokeratology: A Non-Surgical Approach To Myopia Control Technique
In recent years, the prevalence of myopia, commonly known as nearsightedness, has been on the rise, particularly among children. In this informative article from Tosee2020, we will explore orthokeratology as an innovative solution for myopia control, discussing its benefits, the process involved, and its potential long-term impact.
Understanding Myopia and Its Impact:
Before delving into orthokeratology, it’s important to understand myopia and its potential consequences. Myopia is a refractive error characterized by difficulty seeing distant objects clearly while having a clear vision for close-up objects. It occurs when the eyeball is slightly longer than normal, causing light rays to focus in front of the retina rather than directly on it. If left unmanaged, myopia can progress over time, leading to increasingly blurred distance vision and an increased risk of eye conditions such as retinal detachment, glaucoma, and macular degeneration. Recognizing the significance of myopia’s impact on eye health, researchers and eye care professionals have sought strategies to slow down or halt its progression, and orthokeratology has emerged as a promising avenue.
Orthokeratology: How It Works?
Orthokeratology is a non-surgical method that utilizes specialized gas-permeable contact lenses to reshape the cornea temporarily. The cornea, the eye’s clear front surface, plays a crucial role in focusing light onto the retina. The cornea undergoes controlled reshaping by wearing ortho-k lenses overnight, allowing light to focus correctly on the retina. This results in improved vision during the day without needing corrective eyewear. These lenses are designed with specific curvature and thickness to achieve the desired corneal reshaping effect. It’s important to note that orthokeratology is reversible, meaning that the effects wear off if lens wear is discontinued.

Benefits of Orthokeratology for Myopia Control:
Orthokeratology offers several significant benefits as a myopia control option. Firstly, it provides clear vision during the day without needing glasses or contact lenses, offering convenience and freedom for individuals with active lifestyles or those participating in sports. Secondly, by temporarily reshaping the cornea, ortho-k lenses address the underlying cause of myopia rather than merely correcting the symptom, potentially slowing down the progression of myopia over time. Research suggests that orthokeratology may reduce myopia progression by an average of 43% compared to traditional corrective eyewear. Additionally, ortho-k lenses are safe and suitable for various age groups, including children as young as six, making them a viable option for myopia control in pediatric patients.
The Orthokeratology Process:
The orthokeratology process begins with a comprehensive eye examination by a qualified eye care professional experienced in ortho-k fitting. This examination assesses the patient’s overall eye health, refractive error, corneal shape, and suitability for orthokeratology. If deemed suitable, the eye care professional will take detailed cornea measurements to customize the ortho-k lenses for a precise fit. The patient will be trained on proper lens insertion, removal, and care. Following the recommended wearing schedule, typically overnight, is important to achieve the desired corneal reshaping effect. Regular follow-up visits will be scheduled to monitor progress, ensure the lenses fit properly, and provide the desired vision correction.
Long-Term Impact and Safety Considerations:
Orthokeratology has shown promise in slowing down the progression of myopia, which can have significant long-term benefits for eye health. By reducing the elongation of the eyeball associated with myopia, ortho-k may help mitigate the risks of developing sight-threatening eye conditions later in life. However, it’s important to note that the long-term effects of orthokeratology on myopia control are still being studied, and individual results may vary. Additionally, like any contact lens wear, proper hygiene and lens care are crucial to prevent complications such as infections or corneal irritation. Regular follow-up visits with the eye care professional are essential to monitor eye health and ensure the continued effectiveness and safety of ortho-k lenses.
Is Orthokeratology Right for You?
While orthokeratology offers exciting possibilities for myopia control, it may not suit everyone. Factors such as the severity of myopia, corneal shape, and overall eye health must be carefully evaluated by an experienced eye care professional. Commitment and compliance are also essential, as the process requires nightly lens wear and regular follow-up visits. It’s important to have realistic expectations and understand that orthokeratology provides temporary vision correction, and discontinuing lens wear will lead to a return of myopic vision. Consulting with an eye care professional specializing in orthokeratology will help determine if this non-surgical approach is the right choice for you or your child.
Conclusion:
Orthokeratology, or ortho-k, offers a non-surgical and potentially effective method for myopia control. By temporarily reshaping the cornea with specialized contact lenses worn overnight, ortho-k provides clear vision during the day without needing glasses or daytime contact lenses. The process has shown promising results in slowing down the progression of myopia, potentially reducing the risks of associated eye conditions. However, consulting with an experienced eye care professional at Tosee2020 is crucial to determine the suitability and understand the commitments and considerations involved.
