Ortho-K cannot completely restore clear vision after just one night of use. Instead, patients will gradually notice positive changes in their vision.

First day

After the first night of wearing Ortho-K lenses, patients may experience significantly improved vision but not yet fully sharp. It’s essential to persist in wearing them and follow up with regular appointments with an optometrist to assess compatibility and make necessary adjustments to ensure safety and effectiveness.

After one week

For some patients, vision may already be restored to sharpness at this point. Additionally, patients may notice halos around lights, especially in low-light conditions. This is normal and will typically disappear within a few days to a few weeks.

After one month

Most patients can achieve clear daytime vision after one month of using Ortho-K lenses. To ensure long-term stability and effectiveness, it’s important to adhere to regular follow-up appointments every 1-3 months with an optometrist.

Depending on the degree of refractive error and the level of adjustment of the lenses, patients can expect their vision to improve as follows:

  • For low myopia (under -2.00D), clear vision can be achieved after 3-4 days of use.
  • For mild to moderate myopia (-2.00 to -4.00D), clear vision can be achieved after 1 -2 weeks of use.
  • For moderate to high myopia (-4.00 to -6.00D), clear vision can be achieved after 2-6 weeks of use.
  • For high myopia (over -6.00D), clear vision can be achieved after 3-8 weeks of use.

Guidelines for Usage

To achieve the desired effectiveness, patients need to adhere to several rules during the usage process:

  • Visit an optometrist and purchase Ortho-K lenses as prescribed. Do not buy Ortho-K lenses of unknown origin or quality on the market without proper guidance.
  • Follow the instructions for usage (wearing and removing lenses) as directed by the optometrist.
  • Store the lenses properly to prevent breakage, reduce the risk of infection, and extend their lifespan.
  • Adhere to the regular follow-up schedule with the optometrist: 1 week – 1 month – 3 months. Contact the optometrist immediately if experiencing any unusual symptoms for timely assistance.

Following these guidelines will ensure a safe and effective Ortho-K lens experience, while also maintaining optimal eye health.

How to Fit Your Child with Ortho-K

The process of fitting ortho-k lenses is similar for children and adults. Initially, their eye prescription and corneal shape profile are measured to determine suitability for ortho-k.

Prior to wearing the lenses, your child will receive instructions on how to insert and remove them, as well as the necessary care steps. Research indicates that children quickly become proficient at handling contact lenses, typically taking only slightly longer than teenagers to learn.

Once your child feels comfortable handling ortho-k lenses, overnight wear will commence, usually for just one night initially. Corneal topography measurements are then repeated the following morning.

During follow-up appointments, refraction and corneal topography are re-measured to compare against previous readings, assessing the extent of corneal flattening.

Assuming all progresses well, overnight wear continues, with adjustments to the ortho-k lens design made as needed if the changes in eye shape deviate from expectations.

Tips to Care For Your Ortho-K Lenses

Caring for your Ortho-K lenses is crucial to maximize the benefits of this vision treatment and avoid complications. Here are 5 handy tips for safe and effective lens care:

1. Cleaning:

  • Use a specialized cleaning solution provided by your optometry team.
  • Wash your hands thoroughly before handling lenses.
  • Gently massage the cleaning solution on both surfaces for at least one minute.

2. Rinsing:

  • Thoroughly rinse off the cleaning solution using a sterile saline solution.
  • Ensure no residue remains to prevent eye irritation.

3. Storing:

  • Fill the case with a soaking solution after cleaning the lenses.
  • Air dry the case after each use in a clean, non-irritating environment.
  • Replace the case every 2-3 months for optimal cleanliness.

4. Insertion and Removal:

  • Wear Ortho-K lenses while asleep to reshape the cornea.
  • Follow the cleaning and storing steps upon waking up for evening wear.
  • Avoid wearing lenses for extended periods while awake to prevent discomfort.

5. Follow-Up Visits:

  • Your optometry team will monitor your eye health with follow-up appointments.
  • Regular eye exams every 6-12 months ensure the lenses are effective and your eyes remain healthy.

By following these simple yet crucial tips, you can maintain your Ortho-K lenses effectively, ensuring optimal vision correction and eye health.
