Addressing Issues with Orthokeratology Lenses: Solutions for Double Vision - Ophthalmology

More Info

---

When dealing with issues related to orthokeratology lenses, particularly the experience of double vision or ghosting, it’s important to understand the underlying factors that may contribute to these symptoms. Orthokeratology, or ortho-k, involves the use of specially designed contact lenses that reshape the cornea to temporarily correct refractive errors such as myopia (nearsightedness). While many patients experience significant improvements in their vision, some may encounter complications, including double vision.

In your case, the fact that your left eye is performing well while your right eye continues to present issues suggests a few potential areas to explore. Here are some considerations and recommendations:
1. Lens Fit and Position: Although your doctor has indicated that the lenses are positioned correctly, it may be worthwhile to have a second opinion or a more detailed assessment of the lens fit. An improper fit can lead to uneven pressure on the cornea, resulting in visual disturbances. Ensure that the lenses are not only centered but also that they maintain their position throughout the night.

2. Adaptation Period: While your doctor mentioned that adaptation could be a factor, it’s essential to recognize that the adaptation period can vary significantly from person to person. Some individuals may take longer to adjust to ortho-k lenses, especially if there are discrepancies in the refractive correction between the two eyes. If you are still experiencing double vision after a month, it may be worth discussing with your eye care provider whether additional time or adjustments are necessary.

3. Visual Axis and Eye Alignment: Double vision can sometimes be attributed to issues with eye alignment or the visual axis. If one eye is not aligned properly with the other, it can lead to diplopia (double vision). A thorough examination by an eye specialist, including tests for binocular vision and alignment, may help identify any underlying issues.

4. Corneal Shape and Health: The reshaping of the cornea can lead to temporary irregularities in corneal topography. If the cornea is not reshaping evenly, it can cause visual distortions. Regular follow-ups with your eye care provider to monitor the corneal shape and health are crucial. They may recommend additional treatments or adjustments to the lens design.

5. Sleep Position and Lens Care: While your sleeping position may not seem to be a significant factor, it’s still worth considering how you handle your lenses. Ensure that you are following the recommended care instructions for your ortho-k lenses, including proper cleaning and storage. Additionally, if you notice that certain sleeping positions exacerbate your symptoms, it may be beneficial to adjust your sleep habits.

6. Consultation with a Specialist: If the issues persist, consider consulting with a specialist in orthokeratology or a corneal specialist. They may have more advanced techniques or insights into your specific situation and can provide tailored solutions.

7. Alternative Options: If after thorough evaluation and attempts to resolve the issue you continue to experience double vision, it may be worth discussing alternative vision correction options with your eye care provider. This could include switching to different types of contact lenses or considering refractive surgery if appropriate.

In summary, while orthokeratology lenses can provide excellent vision correction, they are not without potential complications. Continuous communication with your eye care provider is essential to address any ongoing issues effectively. Regular follow-ups, thorough examinations, and possibly seeking a second opinion can help ensure that you achieve the best possible outcome with your vision correction.
