Which of the following is used to clean the Goldmann tonometer tip?

• A. Household bleach (1:10)
• B. Alcohol
• C. 3% Hydrogen Peroxide
• D. All of the above

Answer: (D)

Disinfecting the Goldmann tonometer tip between patients is essential because the tip contacts the cornea and can transfer organisms from one eye to the next. There are several effective disinfectants that clinics commonly use, and all three listed options are acceptable when used properly: diluted household bleach (1:10), alcohol, and 3% hydrogen peroxide. Each works to kill a broad range of pathogens, and the tip is designed to withstand these disinfectants as long as you follow the manufacturer’s guidance for contact time and then rinse and allow the tip to dry completely before the next use. The key is to ensure thorough cleaning, proper rinsing to remove residue, and drying, so the tip is safe for the next patient.
