I wore bifocals and had both eyes done last year, one at a time, about 6
months apart. Both times, they sent a van to pick me up and bring me
back, and also for the next days follow-up. You'll definitely need to
find transportation if they don't provide it.
When the cataract was removed, they implanted a lens in my right eye to
correct for distant vision, and in my left eye to correct for near
(reading) vision. I slept through both procedures.
I had to apply eye drops several times a day for a week or two. There
was a patch, made of rigid plastic, I used for 3 - 4 nights to protect
the eye when I slept.
Afterward, I needed to bring a voucher to the registry to remove the
restriction for glasses when I drive. Now I can read, drive, etc.
without needing glasses.
I did have glasses made for times when I want both near and distant
vision in both eyes. Very seldom do I wear them.
No matter how low the risk, there's no guarantee. I would never think of
doing the second eye until I was sure The first was exactly what I wanted.
Your best option now is to go for it and take it one step at a time.
Good luck.
