For 30 years of professional flying I wore contacts for distance correction.
In later life as I began to need reading glasses, I wore those on top of the contacts.
I have a pair of Bi-focal glasses as emergency back up.
My ophthalmologist spotted the start of a cataract in my left eye about 10 years ago (outside the bit I looked through).
It is only now that this cataract has developed sufficiently to reduce my vision in that eye to become a problem.
I will have a new lens put in this winter (fixed, for distance vision), which will correct my myopia in that eye at the same time. This will be done privately, as I`m not blind enough for the NHS to do it.
From all that I have read/heard, choose a surgeon who does lots of them and is aware of the caa rules etc. and it is very straightforward.
