Why do I have glare, flicker, and burning tired eyes?

I am now 68, had Cataract Surgery Feb 2017 with Silicon lenses. Then 5 months later I had YAG, then March 2018 I had PRK to adjust for wrong lenses Rx +1. Eyes feel like I have a cold, but no. Vision now - Left eye has about a -.25D correction and -.25 astigmatism. Right eye just -.25D. Single vision lenses, so I need +2.0 readers. Vision is pretty good but still need glasses for sharp vision to drive and golf. Glare is with single point lights, Flicker bright lights from side. Steve
