Topic: focal length to set with cataract surgery?

I am looking forward to imminent cataract surgery and wonder how reed-making can be affected by this?  my doc advised that i will love living without the glasses, but i love having the four focal lengths with my very near-sighted eyes and tri-focals.  can the detail of reed-making be clear enough with just reading glasses, and does this work without extra lights and magnifiers and hoopla?
