Design outcomes

Primary

Measure	Time frame
We will examine refraction, choroidal thickness, axial length before surgery, and at 3, 6, 9, 12, 24, 36, 48, 60, 72, 96, and 120 months after cataract surgery as primary outcomes.	—

Secondary

Measure	Time frame
We will examine visual acuity, corneal astigmatism, and foveal thickness before surgery and at 3, 6, 9, 12, 24, 36, 48, 60, 72, 96, and 120 months after cataract surgery as secondary outcomes.	—
