[Microsurgery of cataracts in glaucoma].

In a group of 205 implantations of artificial intraocular lenses in 172 patients with glaucoma the authors demonstrate that microsurgery of cataract with implantation, in particular of posterior chamber lenses, has also a permanent hypotonic effect. 155 eyes (75.6%) with primary glaucoma were operated and 50 eyes (24.4%) with secondary glaucoma, 198 times (96.6%) primary implantation was used and 7 times (3.4%) secondary implantation. The highest ratio in the group was formed by extracapsular extractions in 95.0%, intracapsular extractions in 3% and phacoemulsification in 2%. One of the greatest obstacles of microsurgery of cataract in eyes affected with glaucoma is the narrow pupil. The authors give an account of possible solutions of this problem. Vision of 5/10 or better with correction was achieved in 68.8%. The most frequent cause of reduced vision of less than 5/50 was atrophy of the TZN in 11.25% Permanent compensation of intraocular pressure without further treatment was observed in 64.4% during a mean follow-up period of 66.7 months.
