OBJECTIVES: To determine whether live virus can withstand excimer laser ablation and pose a possible health hazard to medical personnel. DESIGN: Experimental study. METHODS: Fibroblasts infected with oral polio vaccine virus were ablated with an excimer laser. The plume was collected using a smoke evacuator and bubbled through viral culture media. MAIN OUTCOME MEASURES: The inlet tube from the smoke evacuator was swabbed and cultured for virus. Liquid from the bubble trap was also cultured. RESULTS: Live virus was shown in the material trapped from the laser plume. CONCLUSIONS: Oral polio vaccine virus can survive excimer laser ablation. Whether other more clinically relevant viruses, such as human immunodeficiency virus, can withstand ablation and remain infectious remains to be determined.
