For many analyses of the vitreous, it is essential to obtain undiluted vitreous specimens under sterile conditions intraoperatively. In this new technique, a metal device is integrated into the aspiration system. The device fits on standard laboratory plastic containers with integrated caps. Undiluted vitreous accumulates in the container, which is then removed and sent to the laboratory. With a new container in place, vitrectomy can be continued as usual. This technique is simple, safe, effective, and inexpensive.
