Orthokeratology reshapes the cornea overnight using special lenses to correct myopia and astigmatism, offering a reversible and convenient alternative to surgery. Understanding how it works and potential complications is important for making an informed decision about this non-surgical vision correction method.
Orthokeratology, or ortho-k, is a non-surgical method to correct vision problems like near-sightedness (myopia). It involves wearing special contact lenses that reshape the cornea, the clear front part of your eye, while you sleep. This reshaping helps you see clearly during the day without the need for glasses or regular contact lenses.
Think of ortho-k as braces for your eyes. Just as braces slowly move teeth into the correct position, ortho-k lenses gently mold the cornea to improve vision. The changes are temporary but can be maintained by wearing the lenses every night.
Ortho-k is suitable for people of all ages, especially those who don’t want surgery. It’s often recommended for children and teenagers whose vision is still changing. This method may also help slow down the progression of myopia in children.

Orthokeratology works by using specially designed contact lenses to temporarily reshape the cornea, the clear front part of your eye.
Ortho-k lenses are rigid and gas-permeable, meaning they are sturdy enough to gently reshape the cornea but still allow oxygen to reach your eye, keeping it healthy. By flattening the center of the cornea, the lenses change how light is bent when it enters the eye, correcting your vision.
When you wake up and remove the lenses, your cornea retains its new shape for a while, giving you clear vision throughout the day.
Here’s a simple breakdown of how it works:
Ortho-k is ideal for people who want to correct their vision without surgery. It’s especially beneficial for:
Ortho-k is safe for both children and adults. It is particularly recommended for children whose vision is still developing. Since surgical options like LASIK and PRK are not suitable for children, ortho-k offers a non-invasive way to manage their vision.
A study published in the Eye & Contact Lens: Science Journal found that children who wore ortho-k lenses experienced significant improvements in quality of life and behavior. They were more confident, willing to try new activities, and participated more in sports and outdoor activities.
For adults, ortho-k provides an alternative to glasses, contact lenses, and surgery, offering flexibility and convenience.
Unlike LASIK and PRK, which involve surgical procedures to permanently alter the cornea, ortho-k is non-surgical and reversible. This makes ortho-k a preferred choice for those who are not ready for surgery or who want a reversible solution. It’s also a great option for those who have conditions that make them unsuitable candidates for laser surgery.
Undergoing orthokeratology treatment involves a few steps and requires some adjustments to achieve the best results. Here’s what you can expect during the treatment process:
Most patients begin to notice vision improvement within a few days to a couple of weeks. The full effect can take up to two weeks or more, depending on the individual’s initial prescription and the rigidity of their cornea. Some people experience significant improvement in just a few days.
During the initial phase of treatment, you may need several follow-up visits to adjust the fit and effectiveness of the ortho-k lenses. These visits are crucial to ensure the lenses are reshaping your cornea correctly and comfortably. Your eye specialist may modify the lenses based on how your cornea responds.
Several factors can influence how quickly you see results with ortho-k:
By following this routine, you can maintain clear vision throughout the day without the need for glasses or daytime contact lenses. Regular follow-up visits are essential to ensure the treatment continues to work effectively and safely.
Orthokeratology, or ortho-k, is generally considered a safe and effective way to correct vision. However, like any contact lens treatment, it comes with some risks that you should be aware of.
One of the primary risks associated with ortho-k is eye infection. Just like with regular contact lenses, improper handling, and poor hygiene can lead to infections. This risk is particularly concerning for children, who might not always follow the best hygiene practices. To minimize the risk:
According to Live Science publication, nearly a million Americans visit their doctor each year due to eye infections caused by contact lenses. Infections can range from mild irritations to more serious conditions that could lead to vision impairment.
Regular check-ups with your eye specialist are essential when using ortho-k lenses. These visits help monitor the health of your eyes and ensure that the lenses are fitting correctly and effectively reshaping your cornea. During these check-ups, your doctor can:
The cost of ortho-k treatment can vary widely based on several factors, including the practitioner’s expertise, geographic location, and the specific needs of the patient.
Generally, the initial fitting and first set of lenses in the US can cost between $1,000 and $4,000. This fee typically includes:
In addition to the initial costs, there are ongoing expenses for maintaining the lenses, including:
Orthokeratology, often called ortho-k, is a non-surgical procedure that uses specially designed contact lenses to temporarily reshape the cornea, correcting vision problems like near-sightedness, farsightedness, astigmatism, and presbyopia. These lenses are typically worn overnight, allowing users to enjoy clear vision during the day without the need for glasses or regular contact lenses.
Ortho-k lenses work by gently flattening the central area of the cornea while you sleep. This reshaping changes how light is focused onto the retina, resulting in clearer vision. The effects are temporary, so the lenses need to be worn regularly to maintain vision correction.
Ortho-k is suitable for people of all ages, including children and adults, who want to avoid glasses or are not ready for surgical options like LASIK. It's particularly beneficial for individuals with near-sightedness, farsightedness, astigmatism, and those experiencing presbyopia.
Orthokeratology (ortho-k) offers a non-surgical, reversible solution to vision correction by reshaping the cornea overnight with specially designed lenses. Suitable for both children and adults, ortho-k provides a flexible alternative to glasses and surgical options. With proper care and regular check-ups, ortho-k can effectively improve vision and potentially slow myopia progression in children.
