Chapel Hill, NC-The confidence of ophthalmologists may have been shaken in regard to disinfectants used to clean examination equipment in the clinical setting. In a recent study, two of four disinfectants that were thought to work effectively to eliminate adenovirus type 8 in the ophthalmology clinic were in actuality not doing so. The good news is that two disinfectants, 70% ethyl alcohol and 5,000 parts per million (ppm) chlorine, did the job when in contact with adenovirus type 8 for as little as 1 minute.
