Optometrist-guided versus self-driven subjective refraction using tunable optics: quantifying the professional's impact.

Although the inter-method differences in task duration did not reach statistical significance (Wilcoxon signed-rank test, p-value M = 0.55; p-value time = 0.88), the interquartile range for the time markedly decreased from 90 seconds in the first repetition to 44 seconds in the third, indicating greater consistency between methods after repeated testing.
