Can anything be done to permanently treat crow's feet?

Given your history I would suggest looking into microneedling. Not RF microneedling but regular microneedling with perhaps the addition of PRP. This procedure has a very low risk of pigmentation issues. You will require several sessions and yearly maintenance along with Botox but you will get very nice results.

Great question - it would be wonderful to eliminate the lines permanently if it could be done, however it can't be done.
The reason is that the lines are mostly from contraction of the underlying muscles. The muscles can be weakened with Botox or other neuromodulators to reduce the lines. Using the right dose in the correct area regularly can really help. These medications usually need to be repeated 3-4 times per year.
If you have permanent lines as well as lines from muscle movement, they can be helped with laser treatments, and this can be done at or around the time of upper eyelid surgery, however as you mentioned, you will have to be careful about this due to your skin type and the redness that occurs.
All the best to you,

Botox is the quickest way to soften the appearance of crow's feet. If you are finding that it doesn't produce the results you want you may be a better candidate for either laser resurfacing or a lift. Nothing is permanent as you will continue to age, but there are treatments for improvement. I encourage you to meet with a board certified plastic surgeon near you to discuss your concerns and learn more about options.
