What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Uncorrected Intermediate Visual Acuity
Time Frame: 1 year after surgery
Binocular Uncorrected Intermediate Visual Acuity, measured at 1 meter and 50 centimeters measured in decimal visual acuity. Decimal visual acuity is the normal method to measure visual acuity in Japan. A higher decimal visual acuity value indicates better visual acuity. 0.5 in decimal visual acuity means 20/40 in Snellen fraction.
1 year after surgery
Uncorrected Distance Visual Acuity
Time Frame: 1 year after surgery
Binocular Uncorrected Dinstance Visual Acuity measured in decimal visual acuity. Decimal visual acuity is the normal method to measure visual acuity in Japan. A higher decimal visual acuity value indicates better visual acuity. 0.5 in decimal visual acuity means 20/40 in Snellen fraction.
1 year after surgery
Uncorrected Near Visual Acuity
Time Frame: 1 year after surgery
Binocular Near Visual Acuity measured in decimal visual acuity. Decimal visual acuity is the normal method to measure visual acuity in Japan. A higher decimal visual acuity value indicates better visual acuity. 0.5 in decimal visual acuity means 20/40 in Snellen fraction.
1 year after surgery
