Abstract Details


to reveal the features complicating phacoemulsification surgery


The Khabarovsk branch of the State Institution Eye Microsurgery Complex named after S.N. Fyodorov, Khabarovsk, Russia


61 patients (61 eyes) with combination of primary open-angle glaucoma (POAG) and age-related cataract for whom phacoemulsification was planned. Age - from 56 to 87 years. Men - 29, women - 32. In all patients permanent normalization of intraocular pressure (IOP) was reached. Initial stage of POAG - 17 eyes, developed - 12, hard - 32. Level of IOP made from 10 to 15 mm Hg, on the average - 12,2 mm Hg. In 34 eyes normalization of IOP was reached after antiglaucoma surgeries. In 27 eyes - due to instillations of hypotensive preparations. Any anatomo-morphological factors creating risk of development intra- and postoperative complications after phacoemulsification were revealed.


In all 12 eyes after antiglaucoma surgeries of penetrating type the narrow, rigid pupil was noted: in 7 eyes there were extensive back pigmentary synechia, the pupil didn't extend after mydriatics instillations. In 5 eyes maximum medicamentous mydriasis made 4-5 mm. The lens incomplete dislocation, defects of Zinn's ligament tissues of ¼-½ circles were found in 4 eyes. In all 12 eyes after antiglaucoma surgeries of penetrating type the dense nucleus of a lens was noted. In 20 eyes after antiglaucoma surgeries of non-penetrating type the rigid pupil was revealed, in 17 eyes - mydriasis to 5 mm, in 14 eyes - a dense nucleus of a lens, in 6 eyes - the lens incomplete dislocation. In 16 eyes on a hypotensive regimen the rigid pupil was noted (maximum mydriasis to 5-5,5 mm), in 13 eyes - a dense nucleus of a lens, in 3 eyes - a lens incomplete dislocation took place.


1. At combination of POAG and cataract the increased risk of complications of a phacoemulsification takes place in 79%. 2. Most often met: rigid pupil, lens incomplete dislocation; the increased density of a lens nucleus, back pigmentary synechia. FINANCIAL INTEREST: NONE
