Usually. With modern cataract surgery, the visual results are usually excellent. Assuming the person does not have any underlying issues with the health of their eye, cataract surgery generally provides excellent vision at distance, usually without glasses. Patients usually need reading glasses with routine cataract surgery.
Most of the time! With today's procedures and lens implants most people can see immediately after surgery. It is not uncommon for the vision to fluctuate after the surgery. This usually is blurring /and clouding of the vision and usually resolves in the first 24 hours. Some people may take longer, and usually is not a reason for concern. Follow with your surgeon if you have a concern.
