Why use “Slit Lamp Shield”?
As part of our local experience of stepping up COVID-19 infection control measures in ophthalmology clinics, we recommend installing protective shields on slit lamps. We believe the close proximity between ophthalmologists and patients during slit lamp examination could put doctors at risk of infection, as droplets from coughs or sneezes could spread the virus to anyone less than 6 ft away. The measured distance between the doctor’s and patient’s face on a standard tower slit lamp is just about 1 ft, while that with a portable slit lamp is about 7–8 inch only. These distances are indeed closer than that seen on routine physical examinations, for example, respiratory examination on a medical ward. These shields can therefore act as an effective barrier in addition to other personal protective equipment.
