I remember watching some North Korea documentary where an eye surgeon was visiting to do cataract replacements. He set up in some community center and had dozen of people waiting for surgery. It can take about 10 minutes to perform the replacement and you can leave pretty quickly afterwards. It's an amazingly simple surgery that has a massive increase in quality of life for the patient. The only aftercare is an eye patch and drops to increase tear production to help heal the incision. Once a doctor has all the equipment set up, they could easily do a hundred replacements over a few days. Add to the fact that these doctors and nurses are doing work in third world countries where they may be there as volunteers and the price of the surgery is massively reduced.
