Post-Cataract Surgery: Why Is My Right Eye Image Smaller and Blurry? - Ophthalmology

After cataract surgery, it is not uncommon for patients to experience differences in vision between their operated eye and their non-operated eye. In your case, you have noted that the image and text size appear smaller and less clear in your right eye, which underwent surgery, compared to your left eye, which has normal vision. This situation can arise due to several factors related to the surgical procedure, the type of intraocular lens (IOL) used, and the healing process.

Firstly, the type of IOL implanted during cataract surgery can significantly affect visual outcomes. You mentioned that you received a "Jiangsheng" extended depth of focus lens. These lenses are designed to provide a range of vision, allowing for better focus at various distances. However, they may not always provide the same clarity as traditional monofocal lenses, especially in the early postoperative period. The brain needs time to adapt to the new lens, and during this adaptation phase, discrepancies in image size and clarity can occur.

Secondly, the difference in refractive error between your two eyes can lead to a perception of size difference. If your right eye was significantly more myopic (nearsighted) before surgery, and the IOL was set to correct for that myopia, the brain may perceive objects viewed with the right eye as smaller compared to the left eye. This is due to the way our visual system processes images from both eyes, known as binocular vision. When one eye has a different refractive power than the other, it can create a disparity in how we perceive size and distance.

Additionally, the healing process after cataract surgery can also contribute to temporary visual disturbances. Swelling, inflammation, and changes in the cornea can affect clarity and size perception. It is essential to follow up with your ophthalmologist to monitor your healing progress and address any concerns. They may perform a thorough examination to check for any complications, such as posterior capsule opacification (PCO), which can occur after cataract surgery and lead to blurred vision.

If you are experiencing persistent blurriness and size discrepancies, it is crucial to discuss these symptoms with your eye doctor. They may recommend additional treatments or adjustments to your prescription glasses to help balance the vision between your two eyes. In some cases, further intervention may be necessary if the visual differences do not resolve over time.

In summary, while it is not unusual to experience differences in image size and clarity after cataract surgery, it is essential to communicate these concerns with your healthcare provider. They can provide guidance and reassurance, ensuring that your recovery progresses smoothly and that your visual outcomes meet your expectations. Remember, patience is key during the healing process, and many patients find that their vision stabilizes and improves over time.
