Which procedure should be performed before a Patient wearing contact lenses removes them?

The procedure that should be performed before a patient wearing contact lenses removes them is often related to assessing their visual acuity and overall eye health, which makes visual fields relevant in certain situations.

When a patient is wearing contact lenses, assessing their visual fields can provide important information about their peripheral vision and overall visual field integrity. This assessment can be crucial when considering the cumulative effects of wearing contact lenses on a patient's vision, as prolonged use can potentially impact their field of vision or indicate underlying issues.

In contrast, the other procedures, while useful in their own right, serve different purposes that are not necessarily linked to the immediate assessment of a patient in contact lenses prior to removal. For instance, retinal imaging would be more focused on capturing the health of the retina rather than assessing immediate visual acuity changes due to lens wear. Auto-refraction is aimed at determining refractive errors, typically done without contact lenses, to avoid inaccuracies. Lensometry measures the power of lenses but does not pertain to the patient's condition while wearing their contacts. Therefore, performing visual fields serves a unique and relevant function in this context, making it a suitable procedure to prioritize in this scenario.
