The aim of this paper was to assess the effect of surgical extracapsular cataract extraction with implantation of a posterior chamber lens on normalization of the intraocular pressure in eyes with glaucoma. The relationship between the preoperative depth of the anterior chamber and postoperative normalization of the intraocular pressure was also investigated. The study was carried out on 138 eyes with cataract and glaucoma. Simple open-angle glaucoma was found in 37 eyes (26.8%), simple closing-angle glaucoma in 67 eyes (48.6%), and glaucoma with the pseudoexfoliation syndrome in 34 eyes (24.6%). Before the operation the intraocular pressure in patients ranged from 21-32 mmHg. The depth of the anterior chamber was measured by means of ultrasound. Intraocular pressure was checked for nine months after the operation. In patients with open-angle glaucoma, the depth of the anterior chamber ranged from 3.1-4.0 mm, in closing-angle glaucoma from 2.4-3.2 mm, and with glaucoma in the pseudoexfoliation syndrome from 3.3-4.2 mm. After operation, the depth of the anterior chamber was from 3.7-4.6 mm. Nine months after operation in 64 patients (46.3%), there was no need for pressure-reducing drugs. The highest percentage of patients who did not require treatment (73.2%) was among eyes with closing-angle glaucoma with the smallest depth of the anterior chamber before operation. It seems that measurement of the anterior chamber depth before operation in patients with cataract and closing-angle glaucoma may be an indication of whether cataract extraction with implantation of the lens is sufficient to normalize the intraocular pressure.
