Basics:
- Ortho-K stands for orthokeratology.
- These special contact lenses are worn overnight to gently reshape the cornea, so you can see clearly during the day without needing glasses or regular contact lenses.
- The effect is temporary, meaning you need to wear the lenses every night to maintain clear vision.
- Getting the right fit for Ortho-K lenses requires more visits to the eye doctor compared to regular soft contact lenses.
- New users may find them less comfortable at first, but comfort usually improves within a week.
- Ortho-K is safe when used correctly and with regular follow-up checkups.
What is Ortho-K?
Ortho-K lenses are custom-made, rigid contact lenses that work while you sleep. They reshape the cornea (the clear, dome-shaped front part of the eye) to correct vision, so you don’t need glasses or daytime contact lenses. Ortho-K is commonly used to correct nearsightedness (myopia) and may also help slow its progression, especially in children. These lenses are particularly beneficial for active kids and those who play sports.
How Do Ortho-K Lenses Work?
The eye works like a camera, using lenses to focus light onto the retina. The cornea provides most of this focusing power. Ortho-K lenses slightly flatten the cornea overnight, adjusting its shape to correct nearsightedness. This temporary change allows clear vision during the day without needing glasses or regular contact lenses.
Why is Ortho-K Beneficial for Children?
Ortho-K offers several advantages for children, especially those with myopia. Research suggests that Ortho-K can slow down the progression of nearsightedness, which is a major concern for parents. Additionally, since Ortho-K eliminates the need for daytime glasses or contact lenses, it’s ideal for kids who participate in sports or other activities where glasses might get in the way.
Is Ortho-K Safe for Kids?
Yes, Ortho-K is considered safe for children when used correctly. Studies show that the risk of serious eye infections is low, comparable to wearing daily soft contact lenses. Proper hygiene, correct lens care, and regular check-ups with an eye doctor ensure a safe experience.
What are the Possible Side Effects of Ortho-K?
While Ortho-K is generally well tolerated, some users may experience temporary discomfort, dry eyes, or mild visual distortions during the adjustment period. These symptoms usually improve with continued use. Maintaining good hygiene and following the optometrist’s instructions help prevent any complications.
Is Ortho-K Permanent?
No, Ortho-K is not permanent. If you stop wearing the lenses, your cornea will gradually return to its original shape within a few days. This is why nightly wear is required to maintain the effect. The temporary nature of Ortho-K makes it a flexible alternative to laser eye surgery, as it can be stopped at any time.
Can Ortho-K Slow Myopia Progression?
Yes, studies suggest that Ortho-K can slow the progression of myopia in children by about 50%. This can be beneficial in reducing the risk of long-term vision problems associated with high myopia.
How Are Ortho-K Lenses Fitted?
Getting Ortho-K lenses requires specialized testing by an eye doctor. The fitting process includes:
- Checking your eye prescription and corneal shape using a corneal topographer.
- Designing or selecting a custom Ortho-K lens based on your eye measurements.
- Teaching you how to insert, remove, and care for the lenses.
- Follow-up visits to monitor the fit and ensure the lenses are working correctly.
It usually takes about a week of nightly wear to achieve full vision correction. Some adjustments to the lens design may be needed along the way.
Do Ortho-K Lenses Hurt?
Ortho-K lenses are specially designed to fit closely to the eye, so they don’t usually cause pain. However, new users may feel slight discomfort at first, similar to having an eyelash in the eye. This sensation usually goes away as the eyes adjust to the lenses.
Do kids prefer Ortho-K over glasses?
Yes! Studies show that children aged 6-14 often prefer Ortho-K lenses. They report better vision, more confidence in their appearance, and greater freedom to participate in activities without the hassle of glasses.
How does Ortho-K help parents?
Unlike regular contact lenses, Ortho-K lenses are only worn at night while sleeping. This means parents can easily supervise lens care and cleaning at home, ensuring proper hygiene and usage.
What precautions should parents take?
The biggest risk with any contact lens is infection. To keep your child’s eyes healthy, always ensure they wash their hands before handling the lenses and never let the lenses come into contact with water. Regular check-ups with an eye doctor are also important.
Is Ortho-K Worth It?
Ortho-K is a great option for those who want clear vision without glasses or daytime contact lenses. It’s especially useful for children with progressing myopia and active individuals who play sports. However, it requires commitment to nightly wear and regular checkups to ensure eye health and proper lens function.
Where to Find Ortho-K Lenses??
Ortho-K lenses are prescribed by eye doctors who specialize in this treatment. If you’re interested, consult an optometrist to determine if Ortho-K is suitable for you or your child.
