Orthokeratology
Orthokeratology, otherwise known as orthoK, is a process that uses gas permeable contact lenses to reshape or mold the cornea, similar to retainers for your teeth.
What is orthokeratology?
- Orthokeratology, otherwise known as orthoK, is a process that uses gas permeable contact lenses to reshape or mold the cornea, similar to retainers for your teeth.
- Contacts are worn overnight to reshape the cornea.
- Best for children with an active lifestyle who do not want to wear correction during the daytime.
How does it slow down myopia?
- OrthoK lenses work by promoting myopic defocus on the retina, which optically inhibits ocular elongation.
Advantages
- Wearer is not required to wear any correction or instill any eye drops, ultimately correcting their myopia during waking hours.
- Full treatment is typically achieved in 1-2 weeks depending on the child’s prescription.
- Less invasive and reversible alternative to surgery or more permanent treatment options available.
- Less risk of infection compared to soft lenses.
- Parents are able to help with contact lenses during nighttime compared to soft lenses worn during the day at school.
Disadvantages
- For best results, orthoK lenses should be worn every night for at least 7-8 hours.
Initial lid adaptation and discomfort compared to soft lenses.
