Orthokeratology (Ortho-K)

Orthokeratology, often abbreviated as Ortho-K, is a non-surgical method of vision correction that involves the use of specially designed rigid gas permeable (RGP) contact lenses to temporarily reshape the cornea of the eye. The primary goal of Ortho-K is to correct vision problems, particularly myopia (nearsightedness), but it can also address mild astigmatism and hyperopia (farsightedness) to some extent.

Here’s how Ortho-K works:

  • Custom-Fitted Contact Lenses: An eye care professional designs and fits custom-made RGP contact lenses based on the individual’s eye shape and prescription.
  • Nighttime Wear: These lenses are typically worn overnight while sleeping. During the night, the lenses gently reshape the cornea by applying controlled pressure on the front surface of the eye.
  • Temporary Reshaping: The corneal reshaping effect allows light to be properly focused onto the retina, correcting refractive errors. When the person removes the lenses in the morning, they can enjoy clear vision throughout the day without the need for glasses or regular contact lenses.
  • Daily Maintenance: Proper lens hygiene and regular follow-up appointments with an eye care professional are essential to ensure the safety and effectiveness of Ortho-K.
  • Ortho-K is particularly popular among individuals who want to reduce their dependence on glasses or daytime contact lenses but are not interested in or eligible for surgical procedures like LASIK. It’s also considered a reversible vision correction method; if a person stops using Ortho-K lenses, their corneas will gradually return to their original shape, and their prescription will revert.

It’s important to note that Ortho-K may not be suitable for everyone, and its effectiveness can vary depending on factors like the degree of refractive error and corneal shape. Consultation with an eye care specialist is necessary to determine if Ortho-K is a suitable option for your vision correction needs.
