Used to work for a major LVC provider. The procedure is one of the safe around, however if Lasik (most popular) then you are creating a flap (cutting into the corneal layer using either a blade or laser), lifting it and reshaping the cornea with a laser (this is where a wavefront or custom procedure helps, it is more specific to your cornea). Mild common complications are dry eye, halos (usually when driving at night) through to infections, flap complications or shifts up to sight affecting complications.
Commercially the starting price is rarely paid. Its ratcheted by prescription. then add ons are getting the flap created by a laser (Intralase where i worked though different names at different clinics) which makes a cleaner more consistent cut but doesn’t affect the outcome and wavefront guided which is the custom treatment and should reduce the likes of halos and generally gives a better outcome.
I know people that had it done and were delighted. I know how many people came through the doors and were happy. There are a small few problem cases which should be / are managed like any surgery complications.
Also at 50 you will get nature age related problems with the eye focusing due to the lens losing elasticity which generally results in readers so its not a glasses free for life solution.
