Saline eye wash is fine to use or you can make your own sterile saline solution at home.And I know this is an odd question, but do I need to get some sterile water somewhere or will saline solution that we use be ok to flush it out with before I put the vetericyn in?
For Eyes:
Mix 2teaspoons table salt to a quart of water, bring to boil, reduce to a simmer for 15minutes. Cool. Store in a sanitized jar for up to 24hrs, then make fresh.
