Myopia, or nearsightedness, is increasingly common among children, and finding effective ways to manage it is crucial for their long-term eye health. Orthokeratology, or Ortho-K, offers a promising solution. Here’s a brief overview of what Ortho-K is, how it helps with myopia control, who it’s best for, the fitting process, and some common misconceptions.
What is Orthokeratology
Orthokeratology (Ortho-K) is a non-surgical treatment that uses specially designed contact lenses worn overnight to reshape the cornea. When the lenses are removed in the morning, they provide clear vision throughout the day without the need for glasses or regular contact lenses.
How Does It Help Myopia Control?
Ortho-K is effective in slowing the progression of myopia. By reshaping the cornea, Ortho-K lenses create a peripheral defocus that helps reduce the elongation of the eyeball, which is a major cause of myopia progression. Studies suggest that Ortho-K can cut the annual progression of myopia by up to 50%.
Who Are the Ideal Candidates for Ortho-K?
Ortho-K is suitable for:
- Children and Teens: Especially those whose myopia is still worsening.
- Stable Refractive Errors: Children with a relatively stable myopia prescription.
- Adults with Mild to Moderate Myopia: Ortho-K is best suited for those with mild to moderate myopia. For higher levels of myopia, other treatments may be recommended.
- Individuals whose cornea is not suitable (or other reasons) for laser vision correction e.g. LASIK: Ortho-K offers a non-invasive alternative
- Good Eye Health: Those with healthy eyes and no significant eye conditions.
An eye care professional can help determine if Ortho-K is the right choice for your child.
The Fitting Process of Ortho-K
Here’s a quick look at what to expect:
- Initial Exam: Comprehensive eye exam to assess vision and eye health.
- Lens Selection: Choosing or designing the right Ortho-K lenses for your child.
- Fitting the Lenses: Trying on the lenses and making necessary adjustments.
- Follow-Up: Regular appointments to monitor effectiveness and address any issues.
- Education: Training on lens care and handling.
Common Misconceptions about Ortho-K
Here are some myths and facts about Ortho-K:
- Myth: Ortho-K is dangerous. Fact: Ortho-K is FDA-approved and safe when properly used.*
- Myth: Ortho-K is just for adults. Fact: It is specifically designed for children and teens.*
- Myth: Ortho-K cures myopia. Fact: It controls, but doesn’t cure, myopia.*
- Myth: Ortho-K lenses are uncomfortable. Fact: They are designed for overnight wear and should be comfortable.*
- Myth: Ortho-K results are immediate. Fact: Most see improvement after the first night, but it takes time for full results.*
Conclusion
Orthokeratology offers an effective way to manage myopia in children and slow its progression. If you’re considering Ortho-K for your child, consult with an eye care professional to see if it’s the right fit.
