My mom had it done in her eighties she had very cloudy vision from the cataracts and was able to see clearly as soon as she woke up each time. When tested after the recovery period she had almost 20/20. She needed glasses though for double vision so she had to have prisms. It had nothing to do with the cataracts or the surgery.
The recovery was basically a little over a week and involved antibiotic drops as well as wetting solution and wearing a plastic cupped patch at night so she didn’t bang or rub up against her eye. She also had to wear wrap around dark glasses for a while outside.
