Post-Vitrectomy Vision Changes: Recovery and Correction Options - Ophthalmology

Post-vitrectomy


Hello, Doctor Gao:
I had a vitrectomy on my right eye at Taichung Veterans General Hospital a month ago due to retinal issues.
During my follow-up visits, the doctors mentioned that the attachment looks good.
I feel that my vision in the right eye is slowly recovering, but I am experiencing problems with objects appearing smaller and distorted, which is causing a disparity with my other eye.
I would like to ask:
1.
Will the issues of size reduction and distortion in the surgical eye have a chance to improve during the six-month recovery period?
2.
Can the difference in size perception between my two eyes be corrected by getting new glasses? (My old prescription is R: -8.75, L: -8.25).
Currently, wearing these glasses causes focusing issues.
Thank you for taking the time to answer my questions!

Hello:
1.
Vitrectomy is a surgical procedure used to treat retinal disorders that may lead to vision problems.
The recovery process after surgery varies from person to person; some individuals may gradually recover within a few months, while in some cases, recovery may take longer.
2.
The occurrence of size distortion in vision after surgery may be due to changes in refractive error caused by the procedure.
In this situation, getting new glasses may be a solution.
You mentioned that the glasses you are currently wearing have focusing issues, indicating that your prescription may need adjustment.
It is recommended that you consult your attending physician to determine whether a new prescription is necessary.

Post-vitrectomy vision changes can be a complex issue, and it's understandable to have concerns about your recovery and the potential for vision correction. Let's address your questions one by one.

1. Will the issues of reduced size and distortion in vision improve within the six-month recovery period?
After vitrectomy, it is common for patients to experience changes in their vision, including distortion and size perception issues. These symptoms can be attributed to several factors, including changes in the eye's refractive state, the healing process of the retina, and the brain's adaptation to new visual inputs.
Typically, the recovery period after vitrectomy can last up to six months or longer, and many patients do notice gradual improvements during this time. The brain often requires time to adapt to changes in vision, especially if there has been a significant alteration in the eye's structure or function. While some patients may experience substantial improvements, others may find that certain visual distortions persist.
It is essential to maintain regular follow-ups with your ophthalmologist, who can monitor your recovery and provide guidance on what to expect. If your symptoms do not improve or worsen, further evaluation may be necessary to rule out any complications.

2. Can the size discrepancy between the two eyes be corrected with new glasses?
Yes, it is possible to address the size discrepancy and distortion through corrective lenses. The difference in vision between your two eyes can lead to issues such as double vision or difficulty focusing, which can be particularly frustrating.
Given your previous prescription (R: -8.75, L: -8.25), it is crucial to have a comprehensive eye examination to determine if your current prescription is still appropriate. Changes in the eye's refractive state after surgery can necessitate adjustments in your glasses prescription.
Your ophthalmologist or optometrist can perform a refraction test to assess your current vision and determine the appropriate lens power needed to correct any discrepancies. Additionally, if you are experiencing focusing issues, they may recommend specific lens designs, such as progressive lenses or bifocals, to help with near and distance vision.

In some cases, prism lenses may also be beneficial to help align the images seen by both eyes, reducing double vision and improving overall visual comfort.
Additional Considerations:
- Visual Rehabilitation: If you continue to experience significant visual distortions or difficulties, consider discussing visual rehabilitation options with your eye care provider. This may include vision therapy, which can help improve coordination and integration of visual information from both eyes.

- Patience and Adaptation: Recovery from vitrectomy can be a gradual process, and it is essential to be patient. Your brain may take time to adapt to the new visual signals, and some symptoms may improve as your eyes heal.

- Regular Follow-ups: Keep up with your scheduled follow-ups with your ophthalmologist. They can provide ongoing assessments of your vision and make necessary adjustments to your treatment plan.

In conclusion, while there is potential for improvement in your vision over the next few months, it is crucial to maintain open communication with your eye care provider and address any concerns you may have. They are best positioned to guide you through your recovery and help you achieve the best possible visual outcome.
