Discomfort from cataract surgery is typically minor and may only last a few days. This can make it tempting to go right back to your previous level of activity. It is important to wait at least 10 days before doing any strenuous activity, such as heavy lifting or exercise. Try not to lift anything heavier than 5 to 10 pounds, and keep your head above your body. Avoid swimming or hot tubs for at least 3 weeks. It is important to follow all instructions and recommendations your doctor gives you for a normal recovery.
