Zusammenfassung

Hintergrund Eine postoperative Druckerhöhung nach Kataraktoperation ist ein bekanntes Problem. Eine Operation ohne Viskoelastika kann die Drucksteigerung minimieren.

Patienten und Methoden In einer Gruppe von 33 Augen bei 33 Patienten wurde der Intraokulardruck (IOD) einen Tag vor, sowie 6, 24 Stunden und 7 Tage nach Phakoemulsifikation und Implantation einer faltbaren Silicon-Plattenhaptik Hinterkammerlinse, ohne Viskoelastika und mit Hilfe eines Injektors und eines limbalen Infusionsterminals gemessen.

Resultate Präoperativ betrug der Durchschnittsdruck 16,1 ± 3.9 mm Hg (10 - 28 mm Hg). Die postoperativen Druckmessungen ergaben folgende Werte: nach 6 Stunden: 12,3 ± 3,3 mm Hg (5 - 18 mm Hg, p < 0,0001), nach 24 Stunden: 13,8 ± 2,8 mm Hg (7 - 19 mm Hg, p=0,032), nach einer Woche: 15,5 ± 3,4 mm Hg (10 - 24 mm Hg, p=0,39). In keinem der Augen war der Druck während der ersten 24 Stunden höher als 18 mm Hg. Die 4 Patienten mit Glaukom, bzw. mit PEX, verhielten sich ähnlich. Ihr Ausschluss aus der Gesamtgruppe änderte nichts an den Resultaten.

Schlußfolgerung Der postoperative Druckanstieg nach Kataraktoperation kann vermieden, bzw. minimiert werden, wenn man auf den Gebrauch von Viskoelastika verzichtet. Neben der erhöhten Sicherheit ist die Kostenreduktion ein angenehmer Nebeneffekt.

Background A rise in intraocular pressure (IOP) after cataract operation is a well known problem. Avoidance of the use of viscoelastics seems to solve the problem.

Patients and methods The IOP was measured in a group of 33 eyes of 33 patients one day before, as well as 6 hours, 24 hours, and 7 days after phacoemulsification and implantation of a foldable silicone plate haptic intraocular lens without viscoelastics and by means of an injector and of the anterior chamber maintainer.

Results Mean preoperative IOP was 16.1 ± 3.9 mm Hg (range 10 to 28 mm Hg). Postoperatively mean IOP was 12.3 ± 3.3 mm Hg (range 5 to 18 mm Hg) after 6 hours (p < 0.0001), 13.8 ± 2.8 mm Hg (range 7 to 19 mm Hg) after 24 hours (p= 0.032), and 15.5 ± 3.4 (range 10 to 24) after one week (p= 0.39). In none of the eyes was the pressure in the first 24 hours higher than 18 mm Hg. When excluding the 4 patients with glaucoma and PEX or when taking them as a separate group, the results were similar.

Conclusions Pressure elevation after cataract operation without the use of viscoelastic substances can be avoided, thus contributing not only to lower costs but also to a higher safety.
