Complications occurring during cataract extraction surgery (e.g., torn anterior capsule; posterior capsular rupture, corneal injury such as significant detachment of Descemet’s membrane or significant corneal endothelial damage, inability to adequately remove the crystalline lens material, 2. Vitreous loss or prolapse 3. Zonular weakness, dehiscence or rupture 4. Any capsular bag pathology, fibrosis, or opacification that could not be visualized prior to removing the cataract 5.
