Capsulorrhaphy under local anesthesia?! (photos)

I have assymetry s/p breast aug 4 months post op (transax unders, 405 R, 485 L). My plastic surgeon thinks my left breast(your left as well in pic) appears larger because he made the pocket too big. He is recommending a capsulorrhaphy under local anesthesia. Is this procedure normally done under local or general? Do you think this will fix the problem or did he just choose the wrong implant size? Also, does the right breast look normal? Does not look rounded underneath. Please advise. Thank you.
