This patient has a case of reverse pupillary block, also called LIDRS (lens iris diaphragm retropulsion syndrome) where the iris gets pushed onto the anterior lens capsule and a block is created so that the pressure in the anterior chamber is higher than the pressure in the posterior chamber. This causes the anterior chamber to become very deep and the capsular bag is pushed into the vitreous cavity. This can happen in post-vitrectomy eyes and also those with high myopia, so why is it happening in this case where we are implanting a +20.0 D IOL for emmetropia?
