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 syste
m. The device fits on standard laboratory plastic containers with inte
grated caps. Undiluted vitreous accumulates in the container, which is
then removed and sent to the laboratory. With a new container in plac
e, vitrectomy can be continued as usual. This technique is simple, saf
e, effective, and inexpensive.
