I have used Diamond Eyes with some success on my papillon, and I know people who swear by a smear of vaseline to keep the hair around the eyes from getting moist. Angel Eyes (the antibiotic based treatment) is no longer allowed to be sold in the UK, but a product called Angels Delight has had good reviews. It was originally developed as a nutritional supplement, so should be safe enough. I am now making my own wash - a pinch of Borax substitute, boiled water and Witch Hazel (which seems to be more or less the recipe of the various washes you can buy). It works if I clean her eyes at least once a day, and dry them thoroughly.
