All 20 some optometry schools in the USA now have the same curriculum, as far as I know.
I was actually pretty lucky, my optometry class was among the first ones to include the curriculum to fulfill therapeutic requirements for all states,  even though the state I was in only had diagnostic use of pharmaceuticals at that time.  So when I became licensed in another state by reciprocity, they gave me my full therapeutics license, much to my relief! and despite the fact that I had never held a license for that before.    
 
Taking the coarse requires at minimum, an intensive 3 week course, which means you are not working, you have to put yourself up in a hotel close to the school, and study your butt off.  All that to the tune of at least 15,000 USD.  Thank gawd for dumb luck.  I really dodged a bullet there and only because I saved every scrap of paper regarding my license and continuing ed.  I was nervous because I hadn't really practiced much in 14 years when I lived overseas, but worked 6 months for an opthamologist in my home town when I returned.  He got me back up to speed fast and I am so grateful for what he did for me.  Without his help, it would have been super tough.
