Abstract

[automatically translated] Objective: To evaluate and compare the effectiveness of the most common types of disinfectants for the disinfection of Tonometer cones and draw some indications on the applicability to clinical-diagnostic reality in the field of ophthalmology. Materials and methods: sterile disposable Tonometer cones, previously contaminated with standard strains of Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa and Candida albicans were tested after a simple cleaning or disinfection with 3% hydrogen peroxide, benzalkonium chloride 0.5%, Minuten wipes (ALPRO®), Pantasept® 0.5% according to the guidelines of the CDC in Atlanta. Results: the simple cleansing was ineffective against all species tested while Minuten Wipes was effective except for B. subtilis. The Pantasept® acted after a minute, benzalkonium chloride, while the elimination of B. subtilis required time of less than five minutes. The hydrogen peroxide was effective only with times in excess of five minutes. Conclusions: the need for in ophthalmology numerous and frequent controls, could lead to a shortage in the disinfection of instruments, and the risk of cross infection. This provides the opportunity to seek alternative means such as the use of disposable Tonometer cones which provide a good cost / benefit ratio in favor of patient safety.
