Which practice helps avoid contamination of eye drops?

Avoiding contact with the eye during the administration of eye drops is essential in preventing contamination. When administering eye drops, if the dropper tip comes into contact with the eye or any surface that is not sterile, it can pick up bacteria or other pathogens, which could lead to infection or other complications. By minimizing or eliminating direct contact with the eye, healthcare practitioners can maintain the sterility of the dropper and the medication itself, thereby protecting the patient from potential infections.

While using large bottles, shaking the bottle before use, and using multi-dose vials may have their own considerations and advantages in certain contexts, they do not specifically address the primary concern of contamination during the actual administration of the eye drops. Thus, focusing on not touching the eye directly during this process is critical for safe and effective ocular treatment.
