Orthokeratology, commonly known as
ortho-k, is a non-surgical procedure that involves the use of specially designed gas-permeable contact lenses to temporarily reshape the contour of the cornea. This method is primarily used to correct refractive errors such as
myopia and astigmatism, and it has gained popularity in recent years as an option for children.
How Does Orthokeratology Work?
Ortho-k lenses are worn overnight and gently reshape the cornea while the child sleeps. When the lenses are removed in the morning, the temporary reshaping allows for clear vision during the day without the need for glasses or contact lenses. The effect is not permanent, thus requiring the lenses to be worn regularly to maintain vision correction.Is Orthokeratology Safe for Children?
Orthokeratology is considered safe for children when prescribed and monitored by an experienced eye care professional. Proper hygiene and handling of the lenses are crucial to minimize the risk of
eye infections. Studies have shown that ortho-k can be an effective method for not only correcting vision but also slowing the progression of myopia in children, which is a significant concern for many parents.
What Age is Appropriate for Orthokeratology?
Ortho-k can be considered for children as young as 7 or 8 years old, although the appropriate age may vary depending on the child’s level of responsibility and ability to handle contact lenses. The primary consideration is whether the child and their parents are committed to the nightly lens-wearing routine and follow-up visits with their eye care professional.What Are the Benefits of Orthokeratology for Children?
Natural Vision: Children can experience clear vision during the day without the need for glasses or daytime contact lenses.
Slowing Myopia Progression: Studies indicate that ortho-k can slow the progression of myopia in children, potentially reducing the risk of developing high myopia and its associated complications later in life.
Active Lifestyle: Ortho-k is ideal for children who participate in sports or other activities where glasses or contact lenses might be inconvenient or impractical.
Commitment: The treatment requires a high level of commitment from both the child and the parents to ensure proper use and maintenance of the lenses.
Risk of Infection: As with any contact lens use, there is a risk of
corneal infection. Proper hygiene and regular follow-up visits are essential to minimize this risk.
Cost: Orthokeratology can be more expensive than traditional glasses or contact lenses, as it involves specialized lenses and frequent monitoring by an eye care professional.
How to Determine if a Child is a Good Candidate for Ortho-k?
Not all children are suitable candidates for ortho-k. An eye care professional will conduct a comprehensive eye exam to determine if ortho-k is appropriate. Factors considered include the child's refractive error, corneal shape, and overall eye health. The child's maturity and willingness to adhere to the lens care regimen are also assessed.What is the Process for Starting Orthokeratology?
The process of starting ortho-k involves several steps: Initial Consultation: An eye care professional will evaluate the child's eye health and discuss the benefits and risks of ortho-k.
Lens Fitting: Custom ortho-k lenses are fitted based on precise measurements of the child's cornea.
Adaptation Period: The child will need time to adapt to the lenses, and frequent follow-up visits will be scheduled to monitor progress and make necessary adjustments.
Regular Follow-up: Regular check-ups are essential to ensure the health of the eyes and the effectiveness of the treatment.
Conclusion
Orthokeratology presents a promising option for children with myopia or astigmatism, offering the benefits of clear daytime vision and potentially slowing myopia progression. However, it requires a commitment to proper lens care and regular follow-up visits. Parents and children should work closely with an experienced eye care professional to determine if ortho-k is the right choice for their specific needs.
