Surgeries have been standard practice among medical professionals for so long that you would be surprised if you assume that this was the sort of thing that was only done in our current highly technologically advanced era. The procedures involved in preparing for surgery have definitely improved though, and there is a pretty good chance that there is absolutely no risk of infection anymore now that surgeons know to sanitize their hands and have developed new and better ways to get inside the body so that they can do their work.
However, the truth of the situation is that surgery that is done by hand might soon become a byproduct of a far gone era. This is because of the fact that lasers are now being used to conduct surgery, and the fact of the matter is that they can help make the surgery safer than if it had been done by hand. You can click for more info, but the basic gist of what we are trying to say here is that laser surgery is better for your cataracts than traditional surgery.
With a laser surgery, the incision would end up being way more precise and there would be a far lower risk of your eye getting damaged to any extent at all. That alone makes it a great option that you might want to start exploring in the short term, but there are plenty of other things that need to be considered as well such as the improved results from the surgeries that use it. Lasers are better at making incisions than scalpels in a human hand, so you should prefer it over traditional surgery.
