What is the standard procedure for sterilizing optical instruments?

1. Freezing

2. Washing with soap and water

3. Autoclaving

4. Using alcohol wipes

The correct answer is: Autoclaving

The standard procedure for sterilizing optical instruments is autoclaving. This method uses steam under pressure to kill all forms of microbial life, including bacteria and spores, ensuring a complete level of sterility. Autoclaving is preferred in medical settings because it effectively sterilizes instruments without damaging them, provided they are made from materials that can withstand the high temperatures and steam involved in the process. Other options have limitations: freezing does not effectively kill bacteria or viruses; washing with soap and water removes debris but does not guarantee sterility; and using alcohol wipes can reduce the microbial load but does not achieve complete sterilization. Therefore, autoclaving is the best practice for ensuring optical instruments are completely sterilized and safe for use in clinical environments.
