We describe a new punch for cellulose sponges that helps to standardize the
application of mitomycin during glaucoma filtration surgery. The punch was
used to create 40 cellulose application disks. The height, diameter, and
weight were measured in both wet and dry states. The disk dimensions and
weights were reproducible, with a coefficient of variation less than 5 for
all categories. The punch has been very useful in our clinical practice and
research.
