Eye drops like Vigamox(moxifloxacin) are good ones. Other anti-biotics that you can use include Gatifloxacin, Chloramphenicol, Tobramycin, Ofloxacin etc. Purulent discharge(yellowish in colour) is suggestive of bacterial conjunctivitis. If the discharge is watery then it may be viral conjunctivitis which will not respond to vigamox. Thanks and best wishes.
