# Amniotic membrane

Amniotic membrane is a thin tissue from the innermost layer of the placenta that can be processed and used as a graft on the eye surface. It promotes healing and reduces inflammation in certain corneal and conjunctival diseases.

## When it is used

Surgeons apply it in theatre or clinic.

- Persistent epithelial defects or non‑healing corneal ulcers
- Chemical injuries or severe ocular surface inflammation
- Pterygium surgery or conjunctival reconstruction
- As a temporary bandage or permanently sutured graft

## Benefits

The membrane acts as a biologic dressing.

- Provides a smooth surface that supports regrowth of healthy tissue
- Contains natural anti‑inflammatory and anti‑scarring factors
- Can reduce pain and speed recovery in selected cases
- Derived from screened donors and processed to meet safety standards
