After cataract surgery I have regained my balance? Why?

I need to have more information about your balance issues and the quality of your vision prior to the cataract surgery to be more certain. First, most people with vision problems do not have a great deal of problems with balance. Blind people do not fall over or have severe balance issues. It is possible that the development of a fairly thick cataract in a short period of time could make adaptation difficult and result in balance issues which would resolve with the removal of the cataract. Congratulations on your good vision and the return of your balance.
