Post-Cataract Surgery: Why Is My Right Eye Dimmer Than My Left? - Ophthalmology

After cataract surgery, it is not uncommon for patients to experience differences in visual clarity and brightness between their eyes, particularly if one eye has undergone a more complex procedure or if there are variations in the healing process. In your case, it sounds like your left eye is performing better than your right eye, which you describe as appearing dimmer and having a yellowish tint, similar to wearing tinted glasses.
Several factors could contribute to this phenomenon:
1. Surgical Technique and Healing: If your right eye had stitches or a more complicated surgical procedure, it may take longer to heal compared to your left eye. The presence of stitches can sometimes cause temporary changes in vision until they dissolve or are removed. Additionally, the healing process can vary significantly from one eye to another, leading to differences in visual acuity and brightness.

2. Artificial Lens Characteristics: You mentioned that both eyes received non-spherical monofocal intraocular lenses. However, differences in lens positioning, power, or even the lens material can affect how light is refracted and perceived by each eye. If the lens in your right eye is slightly misaligned or if there are any complications with the lens itself, this could lead to a dimmer appearance.

3. Postoperative Inflammation: After cataract surgery, it is common to experience some degree of inflammation, which can affect vision. If your right eye has more inflammation than your left, this could lead to a perception of dimness. The presence of blood vessels in the white part of your eye (sclera) could indicate irritation or inflammation, which may also contribute to visual changes.

4. Pupil Size and Reaction: You mentioned that your right eye's pupil has changed size. Pupil size can affect the amount of light entering the eye and can also influence depth of focus. If the pupil in your right eye is smaller, it may allow less light in, contributing to the perception of dimness. Over time, as your eye heals, the pupil may return to its normal size and function.

5. Visual Processing: The brain processes visual information from both eyes, and if one eye is not providing clear input, it can affect overall perception. This is particularly relevant if you have a history of amblyopia or other visual discrepancies.

In terms of what to expect moving forward, it is essential to follow up with your ophthalmologist. They can assess the healing process of your right eye, check for any complications, and determine if any interventions are necessary. It is also important to give your eyes time to heal; visual clarity can improve over weeks to months as inflammation subsides and the eyes adjust to the new lenses.

If you continue to experience dimness or other visual disturbances, your doctor may consider additional evaluations, such as checking for posterior capsule opacification (a common complication after cataract surgery) or other issues that could affect vision.
In summary, while it is not unusual to experience differences in vision after cataract surgery, particularly in the early stages of recovery, it is crucial to maintain open communication with your healthcare provider to ensure that any concerns are addressed promptly. Regular follow-ups will help monitor your progress and ensure the best possible outcome for your vision.
