I'm not who you asked, but my family and one of my friends were all the same.

My mom sees halos around lights at night, so much so that she can't drive after sunset. Her eyes are so dry that she gets plugs inserted into her tear ducts to help retain moisture.

My friend who had it done also has severe dry eyes, to the point that he constantly uses eye drops.

In all four cases I know of, the good vision only lasted a few years. Eventually, glasses will be needed again to keep 20/20 vision.
