MPG and fuel costs for summer trip

Wife an I have both had cataract surgery, one eye at a time each, separate surgery and recovery schedules. We both had expenisve Toric lenses installed, not covered by Medicare. My surgery was complicated a little by the fact that I had taken meds for enlarged prostate, had to do extra eyedrops week before surgery. Wife had some pain during surgery and afterward. My surgery was trickier but completely painless. They tell you to hold your eye steady and follow directions during surgery, not hard to do, eye is held mostly immobile and anesthetised. I still have some astigmatism, need glasses for reading and close work. Daylight is much brighter.
