Surgical outcome of combined phacoemulsification and trabeculectomy.
BACKGROUND
A retrospective study was undertaken to evaluate the results of phacoemulsification, intraocular lens implantation, and trabeculectomy in patients with cataracts coexisting with glaucoma.


METHODS
This study consisted of 20 eyes from 19 patients. Fifteen eyes had chronic angle-closure glaucoma and 5 eyes had primary open-angle glaucoma. All cases were followed for a minimum of 6 months (range, 6 to 16 months). The mean preoperative intraocular pressure (IOP) was 17.3 +/- 4.5 mmHg. The mean preoperative visual acuity was 0.05 +/- 0.19. The mean number of preoperative antiglaucoma medications per patient was 2.3.


RESULTS
Postoperatively, all patients except for one no longer required antiglaucoma medication. The mean IOP was 10.7 +/- 3.7 mmHg one month postoperatively and 13.7 +/- 4.3 mmHg at the final follow-up visit. Vision improved in 80% of the patients and remained unchanged in 20%. The failure to achieve improvement was due to advanced optic atrophy. The mean level of surgically induced astigmatism at the final visit was 0.98 +/- 0.91 diopters as calculated by vector analysis. Various extents of fibrin exudate was found in 10 eyes (50%). The most serious postoperative complication, occurring in one eye (5%), was temporary hypotony with moderate choroidal effusion, which later resolved spontaneously.


CONCLUSIONS
Combined phacoemulsification and trabeculectomy is an effective and safe approach for obtaining good visual rehabilitation and glaucoma control.
