Monitoring and Eye Care Tips During Ortho-K Lens Usage

Ortho-K lenses have been proven safe and effective in controlling the progression of myopia and temporarily correcting nearsightedness for users. However, during the initial period, patients may experience some symptoms in their eyes. Read on to distinguish common or unusual symptoms caused by Ortho-K lenses, as well as some other tips to protect your child’s eyes and maximize the benefits of the lenses during usage!

Understanding Common Symptoms in the Initial Period

While Ortho-K lenses do not affect sleep quality, users may feel slight discomfort in the first few days. This phenomenon typically improves over time, so there’s no need to worry excessively. Additionally, users can minimize this condition by applying artificial tears to enhance moisture and support lens movement on the eyes upon waking up.

Some common symptoms include:

  • Sensation of a foreign object and slight discomfort in the eyes.
  • Mild dryness and flaking at the eye corners upon waking up.
  • Unstable vision in the first few weeks of wearing Ortho-K lenses.
  • Glare and halos at night, especially in the first few months of wearing Ortho-K lenses.

Some unusual symptoms include:

  • Eye pain, light sensitivity.
  • Burning, stinging, and excessive tearing.
  • Redness of the eyes.
  • Sensation of the lens sticking to the eye and difficulty removing the lens in the morning.

When encountering unusual symptoms, users should remove the lenses, clean them with preservative-free saline solution, and then wear them again. If the symptoms persist, discontinue lens usage and visit us for examination and advice from an optometrist.

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.
