Before starting accommodative testing, what must be ensured about the patient?

• A. The patient is fully corrected with their refractive error corrected
• B. The patient wears no correction at all
• C. The patient uses a pinhole at distance
• D. The patient wears readers only

Answer: (A)

Accurate measurement of accommodation depends on removing blur caused by refractive error. If the patient isn’t fully corrected, the visual system has to cope with uncorrected blur, which changes how they respond to accommodative demands and can distort results. By having the patient wear their full refractive correction, you establish a stable, baseline optical condition so any measured changes in accommodation reflect true focusing ability rather than compensation for uncorrected refractive error. Using methods that don’t correct vision, like removing correction, pinholes, or relying on readers alone, would reintroduce blur or alter near and distance demands and would not isolate accommodative function. So start with complete, correct refractive correction to ensure the test measures accommodation accurately.
