Refraction changes after cataract surgery?

A little over two years ago, I had cataract surgery on my right (good) eye.
After a few months, presumably after my eye stabilized, I was rerefracted
for glasses. Since then, it appears that that ey has become more myopic.

Is that common? How much time is reasonable after the surgery before glasses
should be fitted? Can the eyeball shape change over a period of 18 months in
someone in his seventies? I have been perusing the recent posts on
defocusing.

It's common to have some change over time even for pseudophakes, but
ususally the changes are small. I'd guess you were "made" a bit myopic
on purpose, as most people are happier with a slight myopia than a
slight hyperopia when accommodation is zero. In fact, I reommend the
first eye to have cataract surgery should be targeted for mild myopia.
Then when the second eye is done, you can target closer to emmetropia if
that's what the patient wants.
