The use of disposable cautery to scrape corneal ulcers.
We used a handheld disposable cautery for the diagnostic scraping of corneal ulcers. Sterility of the tip is obtained by activating the unit until the tip reaches a red-hot color and then allowing it to cool. The unit has a sturdy, well-defined tip, and is self-sterilizing, reusable, readily available, and simple to use.
