• Purpose To evaluate intraocular pressure (IOP) during femtosecond laser–assisted cataract surgery using a fluid-filled interface. Setting Ruhr University Eye Clinic, Bochum, Germany. Design Prospective clinical trial. Methods The absolute IOP was measured with a modified Schiotz tonometer before and after laser-assisted cataract surgery with and without a fluid-filled interface (Liquid Optics interface, Catalys Precision Laser System). Results The study evaluated 100 eyes. Tonometry and laser cataract surgery were completed successfully in all eyes. The mean preoperative IOP was 15.6 mm Hg ± 2.5 (SD). Upon application of the suction ring and vacuum, the mean IOP rose to 25.9 ± 5.0 mm Hg and remained nearly constant after the laser procedure (27.6 ± 5.5 mm Hg). After removal of the suction ring, the mean IOP was 19.1 ± 4.4 mm Hg. The IOP 1 hour after surgery was not significantly higher than the preoperative values. Conclusions The results indicate a minor increase in IOP using the fluid-filled interface. This is in strong contrast to substantially higher values reported in the literature with flat and curved applanating contact interfaces.
