Orthokeratology, commonly referred to as “ortho-k,” is a revolutionary non-surgical procedure that corrects vision problems by reshaping the cornea while you sleep. It involves wearing specially designed rigid gas-permeable contact lenses overnight, which temporarily correct nearsightedness (myopia), farsightedness (hyperopia), and astigmatism so that you can have clear vision during the day without needing glasses or contact lenses. This blog from Estero Optics in FL explores how ortho-k works, its benefits, who can use it, and what to expect if you decide to pursue this treatment option.
What is Orthokeratology?
Orthokeratology is a form of corneal refractive therapy that offers a reversible, non-invasive solution to correct vision. The specially designed ortho-k lenses gently reshape the curvature of the cornea—the clear front surface of the eye—over time. This reshaping corrects refractive errors by altering the way light enters the eye, ensuring it focuses correctly on the retina for clear vision.
How Does Ortho-k Work?
Ortho-k lenses are made from a rigid, gas-permeable material that allows oxygen to pass through to the cornea, which is crucial for overnight wear. Before starting ortho-k, an eye care professional conducts a thorough eye exam to map the cornea using a corneal topographer, which creates a detailed image of the eye’s surface. This map is used to design custom lenses tailored to the specific contours of your eyes.
When you sleep wearing ortho-k lenses, they apply gentle pressure to reshape the surface of the cornea. By the time you wake up and remove the lenses, the cornea holds its new shape for part or all of the following day, providing you with clearer vision without additional corrective eyewear.
Benefits of Orthokeratology
- Temporary Correction of Refractive Errors: Ortho-k is particularly effective for those with mild to moderate myopia. It can also correct hyperopia, astigmatism, and presbyopia to varying degrees, depending on individual factors like the severity of the refractive error and corneal thickness.
- Non-Surgical: Ortho-k offers a non-surgical alternative to LASIK and other vision correction surgeries. It’s an attractive option for those who want to avoid surgery due to personal preferences or medical reasons.
- Reversible and Adjustable: Unlike surgical options, the effects of ortho-k are completely reversible. If you stop wearing the lenses, your corneas will gradually return to their original shape. This adjustability also means that as your vision changes, your lenses can be updated to fit new prescriptions.
- Ideal for Dry Eyes: For those who suffer from dry eyes, ortho-k can be a better alternative to daytime contact lenses, which may exacerbate eye dryness.
- Suitable for Active Lifestyles: Ortho-k is popular among athletes and those with active lifestyles, as it eliminates the inconvenience of wearing glasses or contact lenses during the day.
Who Can Use Ortho-k?
Ortho-k is suitable for individuals of all ages, including children, teens, and adults. It’s particularly beneficial for:
- Children and Adolescents: Research suggests that ortho-k may help slow the progression of myopia in children and adolescents, making it a valuable preventive tool for young individuals with rapidly deteriorating vision.
- Adults with Lifestyle Constraints: Adults who engage in sports or work in dusty, dry, or windy environments often find ortho-k a practical solution.
- Those Not Suitable for LASIK: Individuals who are not candidates for LASIK due to thin corneas, dry eyes, or other corneal issues may consider ortho-k as an alternative.
What to Expect with Ortho-k
1. Fitting Process: The fitting process for ortho-k lenses is critical and involves several visits to an eye care professional. This ensures the lenses are customized for the most effective and comfortable fit.
2. Adaptation Period: There may be a short adaptation period as your eyes adjust to wearing lenses overnight. Initial mild discomfort and blurry vision may occur as the corneas begin to reshape.
3. Maintenance and Care: Proper lens care is essential to prevent infection. Lenses must be meticulously cleaned and stored according to your eye care provider’s instructions.
4. Regular Follow-ups: Frequent follow-up visits are necessary to monitor eye health and the effectiveness of the treatment, especially in the early stages.
Orthokeratology is a compelling option for those seeking a reversible, non-surgical solution to correct refractive errors and potentially slow the progression of myopia in children. By wearing custom-designed lenses overnight, you can enjoy clear vision during the day without the need for glasses or contact lenses.
As with any medical treatment, a thorough evaluation by a qualified eye care professional is essential to determine if ortho-k is the right choice for you. With proper fitting, adaptation, and care, ortho-k can significantly enhance the quality of life for those with vision impairments, providing freedom from conventional eyewear during the day and a safe alternative to corrective surgery.
