Yes, I felt a lot of pressure when I would bend over after my surgery, that lasted for months. I learned to squat or sit while doing things to eliminate any problem. It's always better to be more cautious than not when dealing with your vision and potential problems.
It depends on how your eye has healed and what extent of surgery was required. If you call your doctor with a specific question, he should be able to give a yes or no answer. Ask direct questions (Could I garden? Could I bend? etc).
