I also had PRK after RK surgery, age 52. My RK surgery was also done nearly 20 years ago in both eyes. Target - distance vision.

Question

5 months post-op distance vision poor. Near vision is 20/20. My vision has diurnal fluctuation over 1 diopter that occurs from morn-eve, measured by refraction specialist. Both corneas steepen symmetrically and become more myopic morn-eve. Morning refraction test used for PRK surgery. Distance vision deteriorates horribly from morn-eve because of diurnal shift. Chief complaint-initial visit was fluctuating vision. No multiple refraction tests done morn-eve pre-surgery. Expert comment on this?

PRK after RK can be effective for changing refraction and often has the reputation of helping with the swings in refraction. If you are good in the distance but becoming more myopic later then that's probably the best situation you could hope for. It would be nice to swing between 0 to -1.00 if you have to have variable refraction.
Some have advocated corneal crosslinking but many advise against it with prior RK as corneal irregularities can worsen in theory.
