The Journey to Better Vision: Your In-Depth Guide to Orthokeratology

Orthokeratology, or ortho-k, is a groundbreaking non-surgical vision correction method, offering millions of people an exciting alternative to glasses, daytime contact lenses, and LASIK surgery. Through the use of custom-designed overnight contact lenses, orthokeratology temporarily reshapes the cornea, making it possible to improve visual acuity for common refractive errors like myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. As interest in orthokeratology grows, many patients are curious about the science behind the treatment, the journey they will undergo, and how they can maintain their improved vision long-term.

In this blog series, we will take you on a comprehensive journey through the world of orthokeratology. From exploring the fascinating science that makes vision correction possible to offering guidance on essential pre-treatment steps, discovering the typical ortho-k treatment process, and sharing valuable tips for sustaining improved vision after treatment, we aim to provide an all-encompassing view of the orthokeratology experience.

At Fenton Family Eyecare, our goal is to empower patients with the knowledge and tools they need to make informed decisions about their eye care. With this blog series, we hope to provide not only a deeper understanding of orthokeratology but also a supportive guide to accompany you on your vision correction journey. So, let’s embark on this path together, exploring the exciting world of orthokeratology and uncovering the keys to achieving life-changing vision improvement.

The Science Behind Orthokeratology: How Overnight Lenses Reshape Your Cornea for Better Vision

Orthokeratology relies on specialized gas-permeable contact lenses to gradually reshape the cornea while you sleep. The lenses are custom-designed for each patient, following a detailed mapping of the cornea’s surface. By applying gentle pressure to the cornea, ortho-k lenses encourage a more regular curvature, which allows light to enter the eye more effectively, resulting in clearer vision throughout the day.

The effects of orthokeratology are temporary, and the cornea will gradually return to its original shape if overnight lens wear is discontinued. This temporary nature makes orthokeratology a reversible alternative to surgical interventions like LASIK. It also allows for adjustments in the lens design as your prescription may change over time.

Preparing for Orthokeratology: Steps to Take Before Beginning Your Vision Correction Journey

Before starting orthokeratology treatment, there are several essential steps to ensure a successful and satisfying experience:

  1. Obtain a Comprehensive Eye Exam: A thorough eye examination helps identify any underlying eye conditions that may affect the success of orthokeratology treatment, and it allows your eye care professional to determine your eligibility.
  2. Set Realistic Expectations: While orthokeratology can provide significant improvements in vision, results may vary based on the severity of refractive errors and individual corneas’ characteristics. Discuss your personal expectations with your eye care professional, who can provide a more accurate assessment of potential outcomes.
  3. Choose a Qualified Orthokeratology Practitioner: Ortho-k fitting requires specialized skills and experience to ensure optimal results. Seek a qualified eye care professional with specific expertise and training in orthokeratology.

The Orthokeratology Process: What to Expect During Your Treatment Journey

Your orthokeratology journey will involve several key steps, as outlined below:

  1. Initial Consultation: Your eye care professional will discuss your medical and ocular history and conduct a comprehensive eye exam. They will assess your suitability for orthokeratology and answer any questions or concerns you may have.
  2. Corneal Mapping and Lens Fitting: Your practitioner will use devices like corneal topographers or tomographers to map the unique curvature and shape of your cornea to design your custom lenses. Using these detailed measurements, the lenses will be custom-manufactured to maximize comfort and vision improvement.
  3. Lens Dispensing and Initial Adjustment: Once your lenses arrive, you will return to your eye care professional to ensure a proper fit. They will train you on proper contact lens insertion, removal, and cleaning techniques.
  4. Follow-up Appointments: Routine follow-up appointments are crucial to track your progress, address any concerns, and monitor the health of your eyes. The frequency of these appointments may vary, initially occurring more frequently and tapering off as treatment progresses.

Life After Orthokeratology: Tips for Maintaining Your Improved Vision and Lens Care Best Practices

To sustain your improved vision after undergoing orthokeratology, follow these essential tips:

  1. Maintain Proper Lens Care: Caring for your ortho-k lenses is vital in ensuring their efficacy and longevity. Clean and store your lenses properly, and replace them according to your eye care professional’s recommendations.
  2. Follow a Consistent Overnight Wear Schedule: Consistency in wearing your ortho-k lenses is key to maintaining your improved vision. Skipping nights can cause your cornea to revert to its original shape and decrease the effectiveness of the treatment.
  3. Attend Regular Eye Checkups: To monitor your eye health and ensure ongoing success with orthokeratology, continue to visit your eye care professional for regular checkups.
  4. Prioritize Sleep Health: Maintaining good sleep habits is essential for both the success of orthokeratology and overall health. Aim for seven to eight hours of sleep per night to give your lenses the time they need to effectively reshape your cornea.


Orthokeratology offers a non-surgical, reversible solution for many seeking vision correction. By understanding the science behind the treatment, preparing for your orthokeratology journey, navigating the treatment process, and adopting best practices for maintaining improved vision, you can achieve life-changing vision results.
