Modeling and simulation of cataract surgery processes

In this paper, we present results of a simulation study that is related to cataract surgeries in an eye hospital in Germany. Cataract extraction is one of the most common and cost effective surgical procedures. We describe the process flow of the cataract surgeries in detail. We are interested in reducing waiting time of the patients and increase utilization of the operating rooms (OR). The data collection and input modeling effort using real-world data is described. The proposed simulation model using the SLX simulation package is presented. We discuss some suggestions for improvements based on the conducted simulation study. Possible extensions of the present research are also suggested.
