This topic is about finding reliable convex wafer options for someone whose stoma has retracted after surgery. The person seeking advice is trying to help their 82-year-old mother, who is experiencing leaks because her stoma is not protruding as much as it used to. They have tried products from Hollister and Convatec and currently prefer Convatec’s moldable wafers. They are looking for recommendations and experiences with convex wafers or systems that can help reduce leakage.

Here are some helpful insights and advice shared by others:

1. Convatec Moldable Convex Wafers
- Many users find these wafers excellent for preventing leaks.
- The Durahesive version forms a tighter and longer-lasting bond, lasting up to 5 days, with minimal leakage.
- Convatec Stomahesive Convex Pouches are preferred by some athletes, lasting about 2 days even with heavy sweating.
- The Convatec Assura one-piece convex pouch works well when used with a Hollister Adapt barrier ring.

2. Hollister Convex Systems
- Switching to a Hollister Convex wafer with Adapt paste and an optional belt has helped some users eliminate chronic leaks and skin irritation.
- Good adhesion is reported during activities like golf in hot, humid conditions, with some users adding medical tape for extra security.

3. Barrier Rings, Pastes, and Seals
- A small amount of Hollister Adapt paste under any wafer can improve the seal.
- Eakin seals used under Convatec or Coloplast systems can significantly reduce leakage.
- Be cautious with extra wax spacers, as they might lift the appliance and worsen seepage.

4. Coloplast Convex Options
- The Coloplast shallow convex one-piece drainable pouch works well for some, with proper stoma measurement being crucial.
- Coloplast Easiflex Soft Seal baseplates have stopped leaks for over 16 months, with each baseplate lasting 2–3 days.

5. Pelican Healthcare
- Flexible flange pouches from Pelican Healthcare are suitable for slightly retracted stomas, though availability outside the UK may be limited.

6. New Hope Custom Appliances
- Custom-made convex wafers are available after an OT nurse takes a plaster cast of the stoma. These are effective for stomas that change shape or are close to the skin. They can be ordered through suppliers like Edgepark.

7. Additional Tips
- An ostomy belt can help keep convex wafers snug against the abdomen.
- Factors like activity level, sweat, and skin sensitivity can affect wear time, so be prepared for some trial and error with different brands.
- Stomal therapy or ostomy nurses can be invaluable for sizing and selecting the right products.
