In 2004 the committee did not come to a consensus on routine use of pre-, peri- or postinjection antibiotics. Since then evidence has emerged suggesting that peri-injection antibiotics do not meaningfully lower the risk of post-injection infection and periodic multi-day administration of topical ophthalmic antibiotics facilitates the colonization of drug-resistant bacteria. For these reasons in 2014 the committee decided against recommending routine antibiotics.
