[Cataract operation following goniotrepanation]. / Die Kataraktoperation nach Goniotrepanation.

Cataract surgery after goniotrepanation has been performed on 75 eyes at the St. Demetrius Hospital Eye Clinic in Thessaloniki , Greece, in recent years. The patients' ages ranged from 46 to 84 years. Intraocular pressure was between 8 and 19 mm Hg in all but 4 eyes which had IOPs of between 22 and 30 mm Hg. In order to leave the fistula untouched, the incision with the Graefe knife was made in the area of the cornea close to the limbus; it was closed with 7 sutures (7-0 silk). Prolapse of the vitreous occurred in 7 cases. It was possible to follow up 52 of the eyes: IOP remained regulated postoperatively with one exception (26 mm Hg); the upper pressure limit was 18 mm Hg.
