For Anastigmatic we have a term and definition in Telescope.

Anastigmatic (Telescope)

Loosely, "corrected for astigmatism", but the more technically correct sense of this term is to describe an optical system which is corrected for spherical aberration, coma, and astigmatism. The point is, that in many common optical designs, spherical aberration and coma tend to be more serious problems than astigmatism, so there isn't much point in correcting astigmatism unless the other two are already dealt with.
