[Cataract-glaucoma combined surgery: comparison between phacoemulsification combined with deep sclerectomy, or trabeculectomy].
ABSTRACT To study the success rate of combined phaco-intraocular lens (IOL)-deep sclerectomy (P-DS), a new perforating filtering surgery, versus phaco-IOL-trabeculectomy (P-T).
Of 38 patients, 39 eyes with cataract and different types of glaucoma, 19 eyes underwent P-DS, and 20 eyes underwent P-T. Patients were prospectively studied.
The follow-up of both groups was 11 +/- 6 months. The intraocular pressure (IOP) decrease in both groups was similar (from a mean preoperative IOP of 26.5 +/- 6.8 mmHg, to a mean postoperative IOP of 14.8 +/- 1.3 mmHg in the P-DS group, vs 25.9 +/- 7.7 mmHg preoperative and 14.8 +/- 2.7 mmHg postoperative in the P-T group). The visual acuity outcome was similar in both groups. The complication rate was significantly lower in the P-DS group.
Deep sclerectomy associated with cataract surgery offers the same IOP reduction and visual acuity outcome. However, the complication rate is significantly lower and allows easier ambulatory care.

ABSTRACT: To compare the outcome of phacoemulsification-intraocular lens (IOL) implantation combined with nonperforating deep sclerectomy (P-DS) with that of phacoemulsification-IOL implantation combined with trabeculectomy (P-T). Glaucoma Unit, Department of Ophthalmology, University of Lausanne, Switzerland. This prospective study involved 60 eyes of 60 patients with cataract and various types of open-angle glaucoma. Thirty eyes had P-DS and 30, P-T. Follow-up was performed at regular intervals for up to 18 months. Mean follow-up was 12.5 months +/- 6.5 (SD) and 12.6 +/- 4.9 months for the P-DS and P-T groups, respectively. Mean preoperative intraocular pressure (IOP) was similar in both groups (24.8 +/- 5.9 mm Hg in the P-DS group and 24.6 +/- 7.2 mm Hg in the P-T group). There was no statistically significant difference in IOP decrease (14.2 +/- 4.0 mm Hg in the P-DS group and 15.2 +/- 2.8 mm Hg in the P-T group). Visual outcome was similar in both groups. The P-DS group experienced significantly less inflammation (40.0% versus 83.0%; P = .0012) and hyphema (6.7% versus 36.7%; P = .010) than the P-T group. Deep sclerectomy combined with cataract surgery resulted in an IOP reduction similar to that with phacotrabeculectomy with the same visual outcome, but the lower complication rate makes ambulatory care easier.Journal of Cataract and Refractive Surgery 04/1999; 25(3):340-6. · 2.55 Impact Factor

ABSTRACT: Filtering procedures have been the gold standard in glaucoma surgery for more than 30 years. Trabeculotomy, deep sclerectomy, and viscocanalostomy might become the procedures of first choice in the future. These new, non-penetrating procedures have not yet been compared to filtering procedures in prospective randomized studies with long-term follow-up. In addition, it is not really known how they modify outflow of the aqueous humor. The surgical technique is described and the most likely underlying effects are discussed. Fistulierende Glaukomoperationen galten in den vergangenen Jahrzehnten als Standardoperation beim Glaucoma chronicum simplex. Möglicherweise könnten die Trabekulotomie, die tiefe Sklerektomie und die Viskokanalostomie in den kommenden Jahren als chirurgische Techniken die fistulierenden Eingriffe als Operationen erster Wahl ablösen. Die Wirkprinzipien dieser neuen, nicht penetrierenden Techniken sind dabei im Detail noch nicht untersucht. Anhand eines klinisch orientierten Erfahrungsberichtes werden mögliche Wirkprinzipien aufgezeigt.Der Ophthalmologe 01/1998; 95(12):835-843. · 0.72 Impact Factor
