Age (years)	70.03	70.42

Figure 1 Difference between spherical equivalent outcome and target.

Notes: Ratio of cases with spherical equivalent outcome within a certain number of designated diopters of target spherical equivalent. Blue bars represent cataract-only cases. Orange bars represent cases of cataract surgery with trabecular microbypass stent. TOST equivalence testing showed the spherical outcomes of the two groups were equivalent (t₁₂₄=4.5, P<0.0001).

Abbreviation: TOST, two one-sided test.
