Had both my eyes done two years ago (one week apart). Surgeon told me different quality of lenses, hence different prices, go for standard lens, you may still need reading glasses with bifocals
1) Painless
2) Drops in eyes, every 10-15 mins for one hour before op
3) Shield on eye for 24 hours post surgery. On eye at night time for one month
4) Drops in eye post surgery through out the day for one month
5) After one month can do everything just as before
Hope that helps
