Common Issues After Wearing Orthokeratology Lenses: What to Know

Issues After Wearing Orthokeratology Lenses

Hello Doctor, I started wearing orthokeratology lenses in early March this year, and I have been wearing them for about five months now.
However, during this time, my vision has not been very stable.
My original prescription was -5.25 in the right eye and -5.75 in the left eye.
Recently, I have noticed a problem, but when I went to the ophthalmologist for an examination, they said everything was fine.
The issue is that my left eye becomes very blurry in the afternoon.
When looking at traffic lights, instead of seeing just one light, I see multiple blurred circles around it.
I consulted the doctor who prescribed my glasses, and he said it was glare, but I don't think it is glare because glare typically has a halo effect, while what I see are many blurred circles.
(In the morning, after I take them off, my vision is normal.)
Another problem is that my vision often appears hazy, as if there is a layer of fog in front of my eyes.
However, strangely, if I yawn and a little tear comes out, my vision becomes very clear.
I have returned to my doctor several times regarding this issue, and each time he tells me that I am still adjusting.
The thing is, I have already experienced the optimal effects of orthokeratology, and it is hard for me to believe that this less-than-perfect correction is still in the trial phase.
I feel like he might be hiding something from me, so I wanted to ask you.

P.S.
I went to another ophthalmology clinic, but they said everything was fine and only prescribed artificial tears.
I genuinely feel that my visibility is lower, but it's strange that no issues have been detected.

Hello Jack,
It is evident that the distribution of tears is uneven, which can create a foggy sensation and cause lens displacement.
This can lead to astigmatism.
Wishing you peace and health.

Sincerely,
Komeilan

It sounds like you are experiencing some frustrating visual issues after starting orthokeratology (OK) lens treatment. Orthokeratology lenses are designed to reshape the cornea overnight to reduce refractive errors, allowing for clearer vision during the day without the need for glasses or contact lenses. However, as with any medical treatment, there can be side effects and complications that arise during the adjustment period.

1. Visual Fluctuations: It's not uncommon for patients to experience fluctuations in vision during the initial adjustment period. This can be due to several factors, including the cornea's response to the lenses, the fit of the lenses, and even environmental conditions. Your description of seeing multiple light sources, especially at night, could be related to corneal irregularities or lens positioning. This phenomenon is often referred to as "ghosting" or "halos," which can be exacerbated by dry eyes or improper lens fit.

2. Dry Eyes and Tear Film Stability: The fact that your vision improves after yawning and producing tears suggests that your eyes may not be adequately lubricated. Dry eyes can lead to blurred vision and discomfort, especially with contact lens wear. Artificial tears can help alleviate this issue, but it's essential to use preservative-free options to avoid irritation. If your eyes are consistently dry, it may be worth discussing with your eye care provider about adjusting your lens wear schedule or exploring additional treatments for dry eye syndrome.

3. Adaptation Period: While your eye doctor has mentioned that you are still adapting to the lenses, it's important to communicate your concerns clearly. The adaptation period can vary from person to person, and while some may experience immediate improvement, others may take longer to adjust. However, if you feel that your vision has not stabilized after several months, it may be worth seeking a second opinion from another eye care professional who specializes in orthokeratology.

4. Lens Fit and Prescription: The fit of the orthokeratology lenses is crucial for optimal vision correction. If the lenses are not fitting correctly, they may not reshape the cornea as intended, leading to visual disturbances. Your eye care provider should perform regular follow-ups to assess the fit and make necessary adjustments to your prescription. If you feel that your concerns are not being addressed, it may be beneficial to seek a consultation with a specialist who has extensive experience with OK lenses.

5. Underlying Conditions: Although your previous eye exams have not revealed any significant issues, it’s essential to rule out any underlying conditions that could be contributing to your symptoms. Conditions such as keratoconus or other corneal irregularities can affect vision and may not always be apparent in standard examinations. A thorough evaluation, including corneal topography, may provide more insight into your situation.

In summary, while some visual disturbances can be expected during the adaptation phase of orthokeratology, persistent issues warrant further investigation. It's crucial to maintain open communication with your eye care provider and advocate for your needs. If necessary, don't hesitate to seek a second opinion to ensure that your vision is being managed effectively. Your comfort and clarity of vision are paramount, and there are solutions available to help you achieve the best possible outcome with your orthokeratology treatment.
