Cataract surgery...

I had both done, at different times. Happy with the results although I had to go back and have them tweek one with some laser. Am very sensitive to bright lights and sunshine but can drive and pass the drivers eye exam without glasses.

My understanding is "most" will need it at some point since it's a cloudy film over the lense of the eye.

Again was awake but not really aware of anything and didn't even have as bad of side effects as a regular eye exam.

Not cheap but worth it if you know the end result.
