If the vitrectomy probe through a lim Pplana phacofragmentation is different bal approach is used and no vitreous prolapse is pre from that in phacoemulsification. The goal is not sent, high suction and low cutting are recommended to remove a hard nucleus. Conversely, if vitreous to crack the nucleus in half but to maintain con prolapse is suspected, the suction rate must not stant contact between nuclear material and the exceed 200 mm Hg. Should the vitrectomy probe be aspiration port by taking small bites along an introduced through the pars plana, it is difficult to advancing line (?nibbling?). If the surgeon carefully maintain its depth and prevent endothelial damage Ppolishes the anterior capsule,36 the risk of should the anterior capsule be breached. Through the nasal pars plana incision, the sur Table 21?7 provides a summary of the various extrac g tion techniques. Primary posterior capsulectomy (and anterior vitrectomy) reduces, but does not elimi nate, this risk. Because a posterior cap known before surgery, certain retinal complica sule rupture was suspected, the lens is removed with the vitrectomy probe; an iridodialysis is also present. It may be difficult to differentiate tissue lesions caused by the intervention from those caused by the original trauma.

The best treatment is lens much lower rates of complications and a significantly removal during complete pars plana vitrectomy. In the context of trauma, this recommen techniques: dation is probably even more true.

Glaucoma is caused by epithelial or fibrous obliteration of the trabecular meshwork, resulting in a reduced outflow facility.
