What are the essential points to consider when getting eye surgery?

I would like to ask a question to those considering eye surgery. What specific precautions should be taken before and after the surgery? Are there any special methods to reduce pain or swelling? Additionally, I would appreciate advice regarding potential issues that may arise during the recovery process leading back to daily life. I would like to hear from those who have personally experienced this. Any information would be of great help to others who are struggling with this decision.
