Question: 1 / 400

If the slit lamp does not slide easily on the tabletop, what should be attempted FIRST?

Replace the lamp

Adjust the height settings

Clean the friction pad (plate)

The first action to take when the slit lamp struggles to slide easily on the tabletop is to clean the friction pad or plate. Over time, dirt, debris, and other contaminants can accumulate on the friction pads, which may increase resistance and hinder smooth movement. Cleaning these components often resolves the issue without needing more extensive measures.

While lubrication of moving parts or adjusting height settings may also help with functionality, these steps are typically secondary to addressing surface cleanliness. Replacing the lamp should be considered a last resort, as it is likely an unnecessary expense if the issue can be corrected through cleaning. Proper maintenance practices, including regular cleaning of friction components, can prevent such problems altogether.
