Myopia control Ortho-K lenses | Dr Rakib Hasan |Myopia Treatment

Orthokeratology (OK) is a non-surgical procedure that uses specialized contact lenses to reshape the cornea while you sleep, with the goal of controlling myopia (nearsightedness) progression. Here’s an overview:

What is Orthokeratology?

Orthokeratology, also known as corneal reshaping or corneal molding, is a procedure that uses customized contact lenses to gently reshape the cornea while you sleep.

How Does OK Work?

  1. Customized lenses: OK lenses are designed to match the unique shape of your cornea.
  2. Worn overnight: You wear the lenses while you sleep, typically for 6-8 hours.
  3. Corneal reshaping: The lenses gently reshape the cornea, flattening it to reduce myopia.
  4. Corrected vision: When you remove the lenses in the morning, your vision is corrected, and you can see clearly without glasses or contacts.

Benefits of OK for Myopia Control

  1. Slows myopia progression: OK has been shown to slow the progression of myopia in children and young adults.
  2. Corrects vision: OK can correct myopia, reducing or eliminating the need for glasses or contacts.
  3. Reversible: The effects of OK are reversible, meaning that if you stop wearing the lenses, your cornea will return to its original shape.
  4. Non-surgical: OK is a non-invasive, non-surgical procedure.

Candidacy for OK

  1. Children and young adults: OK is most effective for children and young adults with progressive myopia.
  2. Mild to moderate myopia: OK is suitable for individuals with mild to moderate myopia (up to -6.00 diopters).
  3. Healthy eyes: Candidates should have healthy eyes, free from diseases or injuries that could affect the cornea.

Risks and Side Effects

  1. Discomfort: Some patients may experience discomfort or dryness when wearing the lenses.
  2. Infection risk: As with any contact lens wear, there is a risk of eye infection with OK.
  3. Corneal abrasion: Rarely, the lenses can cause corneal abrasions or scratches.

Cost and Insurance

  1. Cost: The cost of OK varies depending on the location, doctor, and lenses used.
  2. Insurance: Some insurance plans may cover OK, but coverage varies widely.

Conclusion

Orthokeratology is a safe and effective procedure for controlling myopia progression and correcting vision. If you’re interested in OK, consult with an eye doctor to determine if you’re a suitable candidate.
