What Is Ortho-K, And How Does It Work?

Ortho-K, short for Orthokeratology, uses a customized contact lens to correct your vision by reshaping your cornea. While you wear it overnight, this particularly rigid lens slowly flattens out your cornea, improving your vision. There is no need for glasses or contacts when you awake after sleeping with Ortho-K. Ortho-K can treat myopia or nearsightedness and mild astigmatism. The effect of the Ortho-K lenses usually lasts for at least one day.

Some studies suggest that Ortho-K might slow down the progression of myopia. It is essential to understand that Ortho-K can not permanently correct your vision, and this non-surgical, non-invasive technology is safe for both adults and children.

It is an excellent option if you are tired of wearing glasses or contact lenses during the day and if other corrective surgeries are not an option for you.

Pros and Cons of Orthokeratology (Ortho-K lens)


  • Ortho-K allows you to enjoy clear vision during the day without the need for glasses or daytime contact lenses, providing freedom and convenience.
  • 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.
  • Ortho-K has been proven effective in correcting myopia and astigmatism, making it a versatile option for different vision needs.
  • Some studies suggest that Ortho-K may slow down the progression of myopia in children and young adults, helping to manage nearsightedness.
  • Gas-permeable lenses used in Ortho-K are designed for comfort during sleep, reducing dryness and irritation associated with traditional contact lenses.
  • 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.


  • 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.
  • 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.
  • It may take some time to get used to wearing the Ortho-K lenses during sleep. Initially, some people may experience discomfort or dryness.
  • 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.
  • Proper lens care and hygiene are essential to avoid eye infections and maintain eye health. Cleaning and storing the lenses correctly are vital responsibilities.
  • 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

Ortho-K lenses can be used by children and adults eight and up. Children and young adults are excellent candidates since you must be 18 to qualify for most invasive vision correction procedures.

Ortho-K might be a great option for you if:

  • 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.

To determine if Ortho-K is a good option for you or your child, an extensive eye exam has to be performed.

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.

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.

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.
