Can COVID-19 Be Transmitted Through Eye Care Procedures? - Ophthalmology

COVID-19, caused by the SARS-CoV-2 virus, primarily spreads through respiratory droplets when an infected person coughs, sneezes, or talks. However, there is growing evidence that the virus can also be present in other bodily fluids, including tears, which raises concerns about potential transmission through eye care procedures.
In your situation, where a nurse applied eye drops and touched various surfaces before handling your eyes, there are a few important points to consider regarding the risk of transmission:
1. Surface Contamination: SARS-CoV-2 can survive on surfaces for varying lengths of time depending on the material. For instance, it can remain viable on plastic and stainless steel for up to 72 hours, while on cardboard, it may last for about 24 hours. However, the risk of transmission through surfaces is generally considered lower than through direct person-to-person contact. The nurse's hands could potentially carry the virus if they had recently touched contaminated surfaces, but the likelihood of transmission through this route is not as high as through respiratory droplets.

2. Eye Care Procedures: During eye care procedures, the risk of transmission can be mitigated by strict adherence to hygiene protocols. Healthcare professionals are trained to follow infection control measures, including hand hygiene, the use of personal protective equipment (PPE), and the disinfection of instruments and surfaces. If the nurse did not follow these protocols, it could increase the risk of transmission, but this is generally not the standard practice in healthcare settings.

3. Tears and Conjunctival Transmission: There is some evidence that SARS-CoV-2 can be found in the tears of infected individuals, which raises the possibility of conjunctival transmission. However, this route is considered less common compared to respiratory transmission. The presence of the virus in tears does not necessarily mean it can be transmitted effectively through eye care procedures, especially if proper hygiene practices are followed.

4. Virus Viability Outside the Body: As mentioned earlier, the virus does not survive long outside the human body. It is generally believed that the virus becomes inactive shortly after leaving the host, especially in dry conditions. Therefore, while it can survive on surfaces for a limited time, the risk of transmission decreases significantly as time passes.

In conclusion, while there is a theoretical risk of COVID-19 transmission through eye care procedures, the actual risk is likely low if proper hygiene practices are followed. If you have concerns about potential exposure, it is advisable to monitor for any symptoms of COVID-19, such as fever, cough, or loss of taste or smell, and to consult with a healthcare professional if you develop any symptoms. Additionally, if you feel uncomfortable with the hygiene practices observed during your visit, do not hesitate to voice your concerns to the healthcare facility, as they should prioritize patient safety and infection control.
