Combined small-incision cataract surgery and trabeculectomy--technique and results

Int Ophthalmol. 1992 Sep;16(4-5):409-14. doi: 10.1007/BF00918002.


In a prospective study 35 eyes of 25 patients with coexisting cataract and glaucoma underwent trabeculectomy, phacoemulsification and implantation of a folded polyHema intraocular lens through the trabeculectomy opening. Follow-up ranged from 6 to 27 months (mean 13.3). The mean age was 76.4 (68 to 88 years). 22 eyes suffered from primary open angle glaucoma, 10 eyes from a pseudoexfoliation glaucoma and 3 eyes had a chronic angle closure glaucoma. Preoperatively intraocular pressure was controlled in 10 eyes with a mean medication of 2.1 but uncontrolled in 25 eyes (mean medication: 2.5). The preoperative visual acuity ranged from 20/40 to hand motions. Postoperatively intraocular pressure was controlled (< 18 mmHg) in all (100%) eyes and without therapy in 32 (91%) eyes. Three (9%) eyes had to be treated with topical timolol twice a day after surgery. Mean intraocular pressure dropped from 21.2 +/- 6.0 mmHg preoperatively to 13.5 +/- 2.1 mmHg postoperatively. Vision improved in all but 4 eyes, 25 (74%) achieving a visual acuity of 20/40 or better. The causes for failed improvement or deterioration of vision were senile macular degeneration in 2 eyes and central retinal vein occlusion and vascular optic nerve atrophy in one eye respectively. Post-operative complications included hyphema in 9 (26%) eyes, fibrin effusion to a various extent into the anterior chamber in 19 (54%) eyes and delayed hypotony (< 5 mmHg) with chorioidal effusion in 1 (3%) eye. Fibrin effusion was frequently observed in eyes with intraocular pressure below 10 mmHg, iris surgery and hyphema. Finally the complications did not effect the results regarding visual acuity or glaucoma control.(ABSTRACT TRUNCATED AT 250 WORDS)
