I appreciate the comments by Ritterband et al. It is of interest that they have treated 4 patients with similar infections. In the past, acute postoperative cataract wound infections were extremely uncommon following standard extracapsular cataract surgery and phacoemulsification procedures.
It is our experience that these infections are usually caused by gram-positive organisms. Three of 4 isolates were resistant to ciprofloxacin hydrochloride and ofloxacin. All were sensitive to bacitracin. Bacitracin is readily available as an ointment. I think it is a very good drug to use postoperatively for prophylaxis.
