Abstract

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.
