Indexing and cursors are two different concepts and cursors will use indexes.
Cursor (databases) - Wikipedia, the free encyclopedia[^]
Database index - Wikipedia, the free encyclopedia[^]

As for performance, when you are using cursors you are iterating through the result set and the bottle neck will be your code and not the cursor, and generally if you can do the work without the cursor you are better off.
