One-hundred donor eyes were removed with aseptic precautions and bathed in a solution of thimerosal before corneal grafting. With this treatment, there was an incidence of only 22% positive bacterial cultures, one-half of which were considered potentially pathogenic. This suggests that thimerosal is an effective antibacterial agent. Antibiotic solutions, in particular those containing neomycin sulfate and polymyxin B sulfate, appear to be more specific than thimerosal and may be used as a replacement for the latter or in conjunction with it in treating donor eyes prior to corneal grafting.
