Systematic and objective wet-lab testing of instruments for phacoemulsification: new Formalin Quadrant Model.

ABSTRACT:

Purpose

To validate an improved wet-lab model for systematic and objective efficiency testing of instruments for phacoemulsification.

Setting

Institute of Medical Engineering, Lucerne University of Applied Sciences and Arts, Lucerne, Switzerland.

Design

Experimental study.

Methods

Porcine lenses were incubated for different time spans in formalin to simulate different cataract densities. Lenses were cut in quadrants and emulsified in a silicone test chamber. The use of ultrasound was restricted to full occlusion and the minimal power needed to promote emulsification. Equivalence to the surgical situation and cataract consistency were judged by an experienced surgeon. Efficiency was rated by effective phacoemulsification time, liquid consumption, and total surge
