Vision imbalance after two eye surgeries - #18127

Hello Souhaib Thanks for explaining your situation so clearly. What you’re describing—unequal vision, eye strain, and difficulty focusing—can definitely happen if there’s residual astigmatism or anisometropia (difference in prescription between the two eyes) after surgery. Even if your vision is “90%,” small leftover curvature or differences can cause the symptoms you’re feeling.

Here’s what could be going on: - Residual Astigmatism: If a small amount remains, it can cause blurry or strained vision, especially for tasks like reading or using screens. - Anisometropia:If your two eyes have different refractive powers, your brain struggles to merge the images, leading to discomfort and imbalance. - Post-Surgery Effects:Some people need glasses even after surgery, especially if the correction wasn’t perfect or if healing changed the shape slightly.

Is this normal? Mild imbalance or strain can happen after eye surgery, but ongoing discomfort and poor daily vision aren’t something you should just accept. Many people benefit from glasses or other corrections even after surgery.

What should you do? - Get a comprehensive eye exam: Visit an ophthalmologist or optometrist for a detailed refraction test. This will check for any remaining astigmatism or prescription difference. - Tests recommended: - Refraction (to measure exact prescription for both eyes) - Keratometry or corneal topography (to map the curvature of your cornea) - Visual acuity test (to check sharpness of vision) - Discuss glasses:If tests show residual astigmatism or anisometropia, glasses can help balance your vision and reduce strain.

Thank you

It sounds like your symptoms of vision imbalance could indeed be related to residual astigmatism or possibly anisometropia, where there’s a notable difference in refraction between the two eyes leading to discomfort and strain. Having some remaining astigmatism post-surgery isn’t uncommon, and in some cases, this could necessitate additional correction, often through glasses or contact lenses, to harmonize the visual acuity between both eyes. It’s quite important to reassess your visual prescription in this context. A comprehensive eye examination by an optometrist or ophthalmologist is crucial at this stage. They would likely conduct a refraction test to see if glasses could improve your vision balance. Other tests might include corneal topography to assess the corneal curvature and check for any distortions that weren’t fully corrected post-surgery. In some situations, even though the vision is considered functionally acceptable by surgical standards, the subjective experience you describe, such as difficulty focusing and eye strain, can’t be overlooked. Glasses, even for minimal correction, might provide substantial relief in everyday tasks like reading or screen work. It’s not unusual for patients to require further adjustments or interventions to achieve optimal comfort and function following eye surgery. Rarely, a more invasive revision procedure could be warranted, but typically non-invasive solutions are explored first. Do discuss these symptoms with your eye care provider to pinpoint the cause and devise a suitable management plan tailored specifically for your situation.
