[Cataract extraction and lens implantation in glaucomatous eyes after trabeculectomy].

PURPOSE

Presentation of problems connected with an implantation of eye lens after trabeculectomy with changed anatomic conditions.

PATIENTS AND METHODS

In 51 cases of patients with cataract and glaucoma, following a trabeculectomy operation, ECCE was made by corneal incision and lens implantation into posterior chamber. In the analysis, the following were taken into consideration: state of the eye before cataract operation, intrasurgical difficulties with necessary application of additional surgical actions, evaluation of postoperative course.

RESULTS

In 41.1% of patients, surgical operations followed a non-typical way and the below procedures were necessary: loosening of adhesions, mechanical pupillary dilation, tearing off fibrous or stained membrane, iridorrhaphy and pupil reconstruction. Posterior chamber lens was implanted in 96% of patients and the following acuity was achieved: 0.5-1.0 in 25 eyes, 0.3-0.4 in 13 eyes, 0.02-0.2 in 10 eyes. There was no acuity improvement in 3 eyes only.

CONCLUSIONS

Operation posterior chamber lens implantation after trabeculectomy can proceed in a non-typical way because of changed anatomic conditions. Postoperative functional results depend on the degree of nerve lesion (injury), but they are often better than preoperative prognoses indicate.
