Post-Surgery Strabismus Issues: Managing Astigmatism and Eye Alignment - Ophthalmology

Postoperative issues following strabismus surgery?


Hello, doctor.
Thank you for answering my questions.
I previously underwent surgery for exotropia, but postoperatively, I developed high astigmatism and my left eye has a tendency to see objects tilted.
This condition has not improved with age, and as I get older, I notice that when I look at the same object for a long time or take a passport photo, my left eye tends to turn inward, which has significantly affected my confidence in social situations.
I am currently wearing glasses with prisms, but sometimes even with the glasses on, my vision appears tilted.
Additionally, when I wear the glasses to read or focus on nearby objects, I experience a sense of distance and slight blurriness, but it improves when I look at things farther away.
I am unsure if this is related to wearing the prisms.
Could you please advise on ways to improve these two issues?

Dear Ms.
Amy: Regarding the questions you raised: 1.
High astigmatism can be addressed with laser treatment.
2.
The misalignment of your vision indicates that the previous strabismus surgery was insufficient, and a second surgery may be necessary.
The Hualien Hospital of the Ministry of Health and Welfare is concerned about you.

Post-surgery strabismus issues, particularly those involving astigmatism and eye alignment, can be quite challenging for patients. It’s understandable that you are feeling concerned about your vision and its impact on your confidence, especially in social situations. Let’s break down your concerns and explore potential solutions.

Firstly, it’s important to recognize that strabismus surgery aims to improve eye alignment, but it does not always resolve all visual issues, such as astigmatism. Astigmatism occurs when the cornea or lens of the eye is irregularly shaped, leading to blurred or distorted vision. In your case, the presence of high astigmatism post-surgery may be contributing to the visual distortions you are experiencing, such as the "tilting" of objects and the distance perception issues when reading or focusing on near objects.

The fact that you are experiencing left eye inward deviation (esotropia) when focusing on objects for extended periods suggests that your eye muscles may not be functioning optimally together. This could be due to a variety of factors, including muscle imbalance, the effects of surgery, or even the adaptation to your new visual environment. The use of prism glasses is a common approach to help manage strabismus and can assist in aligning the images seen by both eyes, but it may not completely eliminate the symptoms you are experiencing.

Here are some strategies that may help improve your situation:
1. Regular Follow-Up with an Eye Specialist: It is crucial to maintain regular appointments with your ophthalmologist or optometrist. They can monitor your eye alignment and astigmatism and make necessary adjustments to your prescription or treatment plan.

2. Vision Therapy: Vision therapy is a structured program of visual activities designed to improve eye coordination and focusing abilities. This therapy can be particularly beneficial for individuals with strabismus and may help in retraining your eyes to work together more effectively. Discuss this option with your eye care provider.

3. Adjusting Prism Prescription: If you are currently using prism glasses, it may be worthwhile to revisit your eye care professional to reassess the prism strength. Sometimes, adjustments can lead to significant improvements in comfort and visual clarity.

4. Contact Lenses: In some cases, contact lenses can provide a better visual experience than glasses, especially for individuals with high astigmatism. They can reduce distortion and provide a wider field of vision, which may help with your perception issues.

5. Surgical Options: If your strabismus and astigmatism remain problematic despite conservative measures, further surgical intervention may be considered. This would typically involve a thorough evaluation by a specialist in strabismus surgery to determine if additional procedures could help align your eyes more effectively.

6. Lifestyle Adjustments: Incorporating regular breaks during activities that require prolonged focus, such as reading or using a computer, can help reduce eye strain. The 20-20-20 rule is a useful guideline: every 20 minutes, look at something 20 feet away for at least 20 seconds.

7. Counseling and Support: If your visual issues are affecting your confidence and social interactions, consider seeking support from a counselor or therapist. They can help you develop coping strategies to manage any anxiety related to your vision.

In conclusion, while post-surgery strabismus issues can be complex, there are multiple avenues to explore for improvement. Collaborating closely with your eye care team will be essential in finding the most effective solutions tailored to your specific needs. Remember, you are not alone in this journey, and with the right support and interventions, there is potential for improvement in your visual experience and overall confidence.
