Ortho-K (Orthokeratology): Non-Surgical Vision Correction Technique

Imagine waking up every morning with a clear vision, free from the constraints of glasses or contact lenses. For those seeking an alternative to traditional vision correction methods, Orthokeratology, also known as Ortho-K or corneal reshaping therapy, presents an innovative and non-surgical solution. In this blog, we explore the world of Ortho-K, its benefits, and how it can transform your vision and lifestyle.

What is Orthokeratology (Ortho-K lens)?

Orthokeratology, commonly known as Ortho-K lens or corneal reshaping therapy, is a non-surgical vision correction technique. It involves the use of specially designed gas-permeable contact lenses that are worn overnight to gently reshape the cornea, the clear front surface of the eye. This temporary reshaping of the cornea allows light to focus accurately on the retina, providing clear vision during the day without the need for glasses or daytime contact lenses. Ortho-K is effective in correcting myopia (nearsightedness) and astigmatism. It offers a reversible and non-invasive alternative to traditional vision correction methods and is particularly suitable for individuals with active lifestyles seeking freedom from glasses.

How does Ortho-K Work?

Ortho-K, or Orthokeratology, is a non-surgical vision correction method that uses specialized gas-permeable contact lenses worn overnight. These lenses gently reshape the cornea, the eye’s front surface. The corneal reshaping temporarily corrects refractive errors like myopia, and astigmatism. Upon waking, the lenses are removed, allowing you to enjoy clear vision during the day without glasses or daytime contact lenses. The effect is temporary, necessitating nightly lens wear to maintain clear vision. Regular follow-up visits are essential to monitor progress and ensure effective vision correction. Ortho-K lenses offer a safe and reversible alternative for active individuals seeking freedom from glasses during the day.

Pros and Cons of Orthokeratology (Ortho-K lens)


  • Glasses-Free Daytime Vision: Ortho-K allows you to enjoy clear vision during the day without the need for glasses or daytime contact lenses, providing freedom and convenience.
  • Non-Surgical and Reversible: It is a non-invasive and reversible procedure, meaning that if you decide to stop using Ortho-K lenses, your cornea will return to its original shape.
  • Effective for Various Refractive Errors: Ortho-K has been proven effective in correcting myopia and astigmatism, making it a versatile option for different vision needs.
  • Potential Myopia Control: Some studies suggest that Ortho-K may slow down the progression of myopia in children and young adults, helping to manage nearsightedness.
  • Comfort and Convenience: Gas-permeable lenses used in Ortho-K are designed for comfort during sleep, reducing dryness and irritation associated with traditional contact lenses.
  • Suitable for Active Lifestyles: Ortho-K lenses are ideal for athletes and individuals with active lifestyles, as there are no lenses to worry about during sports or physical activities.


  • Compliance and Adherence: Successful Ortho-K requires strict adherence to wearing the lenses every night and follow-up visits with the eye care professional. Non-compliance may lead to less effective results.
  • Temporary Correction: The reshaping effect of Ortho-K is temporary. If lenses are not worn regularly, the cornea will return to its original shape, and the vision correction will be lost.
  • Adaptation Period: It may take some time to get used to wearing the Ortho-K lenses during sleep. Initially, some people may experience discomfort or dryness.
  • Not Suitable for Everyone: Ortho-K is not recommended for individuals with certain eye conditions or irregular corneal shapes. An eye care professional will determine candidacy based on a comprehensive evaluation.
  • Maintenance and Hygiene: Proper lens care and hygiene are essential to avoid eye infections and maintain eye health. Cleaning and storing the lenses correctly are vital responsibilities.
  • Cost: Ortho-K lenses can be more expensive than traditional contact lenses. However, long-term savings on glasses and daytime contact lenses may offset the initial cost.

Candidates for ortho K lenses

Candidates for Ortho-K, or Orthokeratology, are typically individuals who meet certain criteria and have specific vision needs. The following are potential candidates for Ortho-K:

  • Mild to Moderate Myopia: Ortho-K is effective for correcting myopia up to around -6.00 diopters.
  • Astigmatism: It can also correct astigmatism, with or without myopia.
  • Active Lifestyles: People with active lifestyles, athletes, and those engaged in sports may benefit from Ortho-K as it offers freedom from glasses and daytime contact lenses during physical activities.
  • Seeking Freedom from Glasses: Individuals who desire freedom from wearing glasses or traditional contact lenses during the day may find Ortho-K appealing.
  • Not Suitable for LASIK: Ortho-K can be considered as an alternative for those who are not suitable candidates for laser eye surgery.
  • Children and Teens: Ortho-K can be a good option for children and teenagers who may not be comfortable with regular contact lens wear.
  • Dry Eye Concerns: Individuals with dry eye issues may find Ortho-K lenses more comfortable than traditional daytime contact lenses.

Safety and Monitoring

When performed by a qualified eye care professional and with proper patient compliance, Ortho-K is considered safe. Regular follow-up visits are essential to monitor the progress of your treatment and ensure the lenses fit correctly and comfortably.

Orthokeratology, or Ortho-K, opens up a world of possibilities for those seeking an alternative to glasses or daytime contact lenses. With its non-surgical approach and impressive benefits, Ortho-K offers freedom from vision correction devices during the day, clearer vision, and the potential to control myopia progression. If you are looking to transform your vision and lifestyle, consider exploring the world of Ortho-K with the guidance of an experienced eye care professional. Embrace this visionary approach to reclaiming clear, unobstructed sight and experience life without the hassle of glasses or contact lenses.

Is it possible to purchase Ortho-K lenses from retail stores or online shops?

Orthokeratology (Ortho-K) lenses are not typically available for purchase at regular stores or online shops like standard contact lenses or glasses. Ortho-K lenses are specialized medical devices that require precise fitting, customization, and ongoing monitoring by a qualified eye care professional.

If you’re interested in trying Ortho-K for vision correction, the process usually involves the following steps:

  1. Consultation: Schedule an appointment with an optometrist or ophthalmologist who specializes in Ortho-K. They will evaluate your eye health, measure your cornea, and determine if you are a suitable candidate for the treatment.
  2. Fitting and Prescription: If you’re a good candidate, your eye care professional will take detailed measurements of your cornea to design custom Ortho-K lenses that will reshape your cornea overnight.
  3. Trial and Adjustment: You will be provided with the specialized Ortho-K lenses and instructions on how to wear and care for them. You’ll wear these lenses while you sleep, and they will gently reshape your cornea to provide clear vision during the day. There might be a period of adjustment as your eyes adapt to the lenses.
  4. Follow-Up Visits: Regular follow-up appointments will be scheduled to monitor your progress, make any necessary adjustments to the lens fit, and ensure your eyes are responding well to the treatment.
  5. Ongoing Care: Ortho-K lenses need ongoing care and maintenance. Your eye care professional will guide you on proper lens care and replacement schedules.

Given the specialized nature of Ortho-K, it’s important to go through this process under the guidance of a qualified eye care professional. Attempting to purchase Ortho-K lenses without proper fitting and monitoring could lead to discomfort, vision problems, or even eye health issues. Always consult with an eye care professional for personalized advice and treatment.

Ortho-K vs. LASIK: Which is Right for You?

Orthokeratology (Ortho-K)

Ortho-K is particularly popular among people who are looking for a non-surgical, reversible option for vision correction. It’s often used for children and teenagers as it may slow down the progression of myopia.


LASIK is generally chosen by adults who are looking for a permanent solution to their vision problems. It offers rapid improvement in vision and typically involves a short recovery period.

Differences and Considerations between Ortho-K and LASIK

  • Ortho-K is non-surgical and reversible, while LASIK is a permanent surgical procedure.
  • LASIK offers immediate results, while Ortho-K’s results become evident after wearing the lenses for a few nights.
  • Ortho-K is often recommended for younger individuals to control the progression of myopia, whereas LASIK is more suitable for adults.
  • LASIK requires a more thorough eye examination to determine eligibility due to the surgical nature of the procedure.
  • Both Ortho-K and LASIK have their own candidacy criteria and potential risks, which should be discussed with an eye care professional.

Whether Ortho-K or LASIK is the better choice depends on an individual’s specific needs, lifestyle, age, and preferences. It’s essential to consult with an eye care specialist to determine which option is most suitable for your vision correction goals.
