Orthokeratology (Ortho-K)

Orthokeratology (Ortho-K) is a non-surgical method used to correct refractive vision problems, primarily myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. The technique involves wearing specially designed gas-permeable contact lenses overnight that reshape the cornea (the front surface of the eye) temporarily, allowing for clear vision during the day without the need for glasses or contact lenses.

Here’s how it works:

1. Lenses are worn overnight: The Ortho-K lenses gently flatten the central part of the cornea while you sleep. This reshaping is temporary, lasting only for a day or two.
2. Clear daytime vision: After removing the lenses in the morning, you experience clear vision throughout the day without the need for corrective This effect lasts for about 24-48 hours, at which point you would need to wear the lenses again overnight to maintain the effect.
3. Gradual improvement: Over time, with consistent use, Ortho-K can help slow the progression of myopia in children and For adults, it’s mainly used as a way to correct vision without resorting to glasses or surgery.

Benefits:

• Non-surgical: Unlike LASIK or other refractive surgeries, Ortho-K is reversible and non-invasive.
• Convenience: Clear vision during the day without glasses or contact lenses.
• Potential to slow myopia progression: Especially beneficial for children, Ortho-K can slow down the worsening of myopia, potentially reducing the need for stronger prescriptions over time.

Who can benefit from Ortho-K?

• Myopia: Especially in children or teens who may have rapidly progressing
• Mild to moderate astigmatism
• People who want to avoid surgery or are not candidates for procedures like LASIK
• Athletes or people in jobs that require clear vision without glasses 

Limitations:

• Temporary results: The effects are not permanent, meaning you need to wear the lenses regularly to maintain clear vision.
• Not suitable for everyone: Those with certain eye conditions or corneal irregularities might not be good candidates.
• Comfort and care: The lenses need to be cleaned and maintained properly to avoid eye infections or other issues.

It’s a great alternative for people who want to avoid the hassle of glasses or the risks of surgery, but it does require dedication to nightly wear for the desired results.
