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.
