Cut to fit ostomy wafers come with a very small hole cut out of the center, which you then cut further to fit your stoma. You can customize these ostomy barriers based on the size and shape of your stoma. Cut to fit ostomy wafers are especially beneficial for new ostomates because after surgery, your stoma may be swollen and could change as your body is healing. Cut to fit wafers are also helpful for people who are in between sizes or don’t have a perfectly round stoma. Cut to fit wafers are available on both 1-piece ostomy pouches and 2-piece ostomy pouches.
