Zetsu also said
 * he didnt get hit with tsukyomi, he broke through it. yet he experienced that?
 * the air around itachi has shifed, which mean's he's finally getting down to business. can this also hint that he didnt use a serious tsukuyomi? \;_;/\'-'/

It is what sasuke experienced in the genjutsu, he experienced nothing that comes close to torture, except having his eye's plucked out, besides Itachi also made the genjutsu seem as if the battle had continued (again no torture, like in kakashi's case) he wanted to feed sasuke more lies, forcing him to think that he really wanted his eyes. Shisui had both of his eyes plucked out ,Sasuke;_;.

The content and intensity of a genjutsu doesn't strengthen it's hold?....so if itachi used genjutsu on kid sasuke, showing him cute little puppies and sun shining over a sunflower garden,he would not panic,he would be calm because that's not something worth panicking about........now show sasuke hell in a genjutsu, him being tortured by the grim reaper he would be shitting on his diaper. The contents of the genjutsu matters.

He didn't want to defeat sasuke ;_; just exhaust him till his chakra drops to zero, forcing him to squeeze more out and by doing so orochimaru himself would be squeezed out thanks to no more chakra.
