Don't know if it's still the same, but my mother had to go into her next door neighbour's a couple of times a day, for 4 weeks, to put drops in her eyes after the op because she was afraid to do it - and she had to do it twice! Now my mother is on the waiting list and I can't help but wonder if the neighbour would do the same in return! I'm under the impression the procedure is different these days.
The ops went well, and her sight was much better, so it seems like it's pretty successful, either way.
