Why are my pupils different sizes after cataract surgery?
This may be caused by different levels of inflammation, as postoperative inflammation has been shown to vary similarly. Lens thickness may also contribute to the decreased pupil size, as intraocular lens intraocular lens (IOL) is much thinner, thus protruding the iris less than the larger cataractous eye lens.
Can cataracts change pupil size?
This novel investigation of digital analysis in standard Scheimpflug imaging suggests that cataract surgery results in reduced photopic pupil size and resulted in a more circular shaped pupil. These changes appear to be more significant with advancing patient age.

What would cause one pupil to be bigger than the other?
Adie syndrome : Sometimes called Holmes-Adie syndrome, it makes one pupil larger than normal and slow to react to light. The cause is often unknown, but it sometimes happens after an injury or lack of blood flow.
