RnB,
I had my cataract surgery more than 20 years ago.
They were privately funded as I had abandoned health insurance once I got my cancer diagnosis. Public hospital care (without a gap payment) was identical to what my insurance offered WITH a gap payment! Same hospital (Royal Melbourne). Even the same doctors.

So, given that I would be up for a couple of thousand dollars per eye, I planned to have one eye done immediately and wait a month to get the other eye fixed.
The difference the surgery made to that eye was so incredible, the day after surgery I phoned the surgeon and booked my second operation ASAP. One week later I had the second eye surgery.
The surgeon’s secretary said this was a common experience.
SO…
My recommendation is that you book yourself in to have BOTH eyes done on the same day.
You’ll need a driver to bring you home.
And I didn’t experience any pain.
I had no eye patches or the like, just eye drops for a few days. Driving again after 2 days (eye test at local optometrist to confirm visual acuity for VicRoads & change licence to remove the requirement for glasses).
All in all, a very positive experience.
Go for it!
