I had LASIK in the 3rd year of medical school. I don't regret it. I had bilateral mild nearsightedness combined with moderate bilateral astigmatism. Because of the astigmatism, I couldn't tolerate contacts well. Glasses were fine but I didn't like wearing them for activities.
After the procedure, I had some halos, mostly during night driving, which resolved over weeks to months. I also had dry eyes that were worst in the first six months that got progressively better over time. For 6 months I used drops frequently (4+ times a day), then a couple of times a day, and now rarely. Overall, my visual quality now is substantially better than my prior corrected vision. I sometimes get halos or visual effects related to dry eyes which are transient and related to dry eyes. This is resolved with drops or blinking more.
The whole thing about night vision and halos is a little overblown. Put on your glasses, drive down the street at night and look up and stare at the street lamps. Do you see halos and linear streaky reflections radiating out from the light? Probably. Dry eyes as well. Wear your contacts and stare at a PACS monitor for 12 hours and tell me if your eyes are dry. Contacts and glasses don't perfectly correct vision either. They are just (mostly) reversible. Some complications of contacts (severe infection, etc) can have permanent effects as well.
That said, there are complications related to LASIK and you need to be aware of them prior to getting it. I know of at least 5-6 residents in my program who have had it at some point, at least one during residency. It's all about how much risk you can tolerate in your life. The truly bad outcomes are quite uncommon, but read about it and decide for yourself. Then when you decide to get it have the best available person who has done the maximum amount of procedures.
