First keep in your mind that any of the described complication can occur with either ICCE or ECCE. However, ECCE (leaving capsule behind) decreases the chances of many complications. Complications decreased by ECCE are :-Vitreous prolapse & loss Endophthalmitis      Cystoid macular edema Aphakic glaucoma        Fibrous & endothelial ingrowth     Retinal detachment     Neovascular glaucoma          Corneal endothelial damage Anterior uveitis    So, almost all complications are decreased by ECCE except for after cataract, which occurs with ECCE. Once again I remind that any of the complications can occur with ECCE, but the chances are reduced.
