Orthokeratology (Ortho-K) is an innovative, non-surgical vision correction method that can improve eyesight without the need for glasses or daytime contact lenses. By using custom corneal molds, Ortho-K reshapes the cornea overnight. This process temporarily corrects vision problems and offers a convenient alternative to traditional methods.

Eye Society in Chicago, IL specializes in providing Ortho-K services to help patients achieve better vision. Our experienced optometrist, Dr. Tanvi Mago, dedicates herself to guiding you through the process to ensure your satisfaction. Read on to learn more about Orthokeratology and how it could be the solution you’ve been searching for.

What is Orthokeratology?

Orthokeratology is a non-invasive treatment involving the use of custom-made, gas permeable contact lenses. The design of these lenses allows for overnight wear, gently reshaping the cornea and improving vision as you sleep. Upon waking, patients can enjoy clear vision throughout the day without needing glasses or daytime contacts.

Ortho-K lenses are ideal for individuals with mild to moderate myopia (nearsightedness), astigmatism, or hyperopia (farsightedness). With proper use, the lenses can provide a temporary vision correction solution. Ultimately, they make daily activities like driving, reading, and sports more enjoyable.

Who gets Ortho-K lenses?

Ortho-K lenses are suitable for a a wide range of patients and conditions (both children and adults).

Some examples include:

  • People with mild to moderate myopia (nearsightedness)
  • Individuals with astigmatism
  • Patients with mild hyperopia (farsightedness)
  • Children experiencing myopia progression
  • People who are not candidates for corrective eye surgery
  • Individuals with dry eye syndrome or allergies, making regular contact lens wear uncomfortable
  • Athletes or those with active lifestyles who want to avoid wearing glasses or daytime contacts
  • Professionals working in environments where glasses or contacts may be inconvenient or unsafe. For instance, first responders or those in dusty, dirty, or wet conditions

They are especially popular among individuals who cannot undergo corrective eye surgery or those who prefer a non-surgical alternative. Ortho-K is also an excellent choice for people with active lifestyles, as it eliminates the need to wear glasses or daytime contacts during physical activities.

In some cases, Ortho-K can be beneficial in slowing down the progression of myopia in children. By controlling the worsening of nearsightedness, children may experience less dependence on glasses or contacts in the future.

Is Ortho-K safer than corrective surgery?

Orthokeratology is considered a safe and non-invasive alternative to corrective eye surgeries like LASIK or PRK. Since this doesn’t involve a surgical procedure, Ortho-K significantly reduces the risks associated with surgery, such as infection or complications during healing.

While Ortho-K is not entirely risk-free, proper care and hygiene can minimize potential complications. Make sure to have regular check-ups with your eye care professional, like Dr. Tanvi Mago at Eye Society. As a result, you’ll be sure to maintain optimal eye health while using Ortho-K lenses.

How effective is ortho-k in slowing myopia progression?

Ortho-K has shown promising results in slowing down the progression of myopia, particularly in children. Numerous studies have demonstrated that Ortho-K can reduce the rate of myopia progression by approximately 45% compared to conventional glasses or contact lenses. This reduction in myopia progression can lead to a lower risk of developing eye-related complications later in life.

While Ortho-K is effective for many patients, it’s essential to consult with an eye care professional to determine whether this treatment is appropriate for your individual needs.

Is orthokeratology permanent?

When you wear the lenses overnight, orthokeratology provides temporary vision correction that lasts throughout the day.

To maintain optimal vision, patients need to continue wearing Ortho-K lenses every night.

If you discontinue using the lenses, the cornea will gradually return to its original shape, and vision will revert to its pre-treatment state.

Food and Drug Administration (FDA) Approved contact lenses

The FDA regulates the manufacturing and distribution of these lenses, providing patients with peace of mind regarding the quality of the product.
