Had cataract surgery 4 years ago and have off and on dizzy and light headed times
Did you have both eyes done, or just one eye? If you only had one eye done, and there is too much of an imbalance between your eyes, your brain will never adjust to the difference.
Please provide additional info. why are you linking your dizziness to a cataract surgery 4 years ago?
Likely another source. You should seek out a medical doc - it could even be changes in your blood pressure.
