Contaminated Eye Drops: Risks, Symptoms, and Prevention for Patients
Some eye drops can get dirty after you open them, especially if the tip touches your fingers or other surfaces.
This dirt can cause infections that hurt the clear front part of the eye, called the cornea.
If you notice redness, pain, blurry vision, or discharge, you should stop using the drops and see a doctor right away.
Doctors can give medicine to kill the germs and help the eye heal.
Washing your hands, keeping the bottle closed, and not sharing drops can stop the problem from happening in the first place.
Eye drops can become contaminated after opening if the dropper tip touches surfaces or is stored improperly.
Contamination can lead to serious infections such as microbial keratitis, causing corneal ulcers, scarring, and vision loss.
Symptoms to watch for include redness, pain, swelling, blurred vision, tearing, light sensitivity, and discharge.
Prompt treatment with antibiotics or antifungals and early ophthalmic evaluation reduce the risk of permanent damage.
Prevention measures: wash hands, avoid touching the dropper tip, keep the bottle closed, use within expiry, and heed recall notices.
