Optimization of the Oertli CataRhex 3 phacoemulsification machine.

Purpose: The aim of this study was to determine optimal bottle height, vacuum, aspiration rate, and power settings of the Oertli CataRhex 3 phacoemulsification machine.

Methods: Porcine lens nuclei were hardened with formalin and cut into 2.0 mm cubes.

The effect of increasing power when grooving using phacoemulsification.

Purpose: To determine optimal power settings on the Centurion Vision System during the grooving step in cataract surgery.

Methods: Intact porcine lenses hardened by formalin and placed in a chamber designed to simulate the anterior chamber of the eye were used to test longitudinal power at 40%, 70%, and 100% and torsional power at 0%. Flow rate was set at 40 mL/min.

Effect of increasing flow when grooving during phacoemulsification.

Purpose: To determine optimum flow settings on the Centurion Vision System during the grooving step in cataract surgery.

Setting: John A. Moran Eye Center Laboratory, University of Utah, Salt Lake City, Utah, USA.

Identification of Nocardia Species by Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry.

Matrix-assisted laser desorption ionization-time of flight mass spectrometry for identification of Nocardia species remains challenging. By identifying 83.1% (64 of 77) and 80% (8 of 10) to the species and complex levels, respectively, and 94.
