[Cataract surgery in glaucoma patients. Perioperative aspects].

The development of intraocular pressure (IOP) following standard cataract surgery is extremely dependent on the type of glaucoma and the prognosis is especially good for primary angle-closure glaucoma. Cataract extraction usually induces a mid-term and long-term increase of IOP in a well-working filtering bleb. Concerning the choice of intraocular lens (e.g. multifocal or toric) the surgeon has to consider the probability of subsequent incisional glaucoma surgery and the risk of decentration of the capsular bag (e.g. in exfoliative glaucoma or hydrophthalmos). According to the results of recent studies topical prostaglandin therapy does not seem to increase the risk of postoperative macular edema if given before cataract surgery.
