Design outcomes

Primary

Measure	Time frame
Mono- and binocular uncorrected visual acuity in photopic and mesopic conditions, for far, intermediate and near distances, measured at 1 month after surgery: 1.1. Distance visual acuity measured using a 22" LED liquid crystal display system (CC-100 HW 5.0 Series, Topcon) that can display ETDRS charts at 4 meters 1.2. Near visual acuity measured using the Logarithmic Visual Acuity Chart 2000 New ETDRS (Precision Vision, Lasalle, IL) at 33 centimeters 1.3. Intermediate visual acuity, measured with the same chart as near acuity (Logarithmic Visual Acuity Chart 2000 New ETDRS (Precision Vision, Lasalle, IL)) and the value adjusted for the 60 centimeter distance For photopic visual acuity measurements, room luminance was 85 candelas [cd]/m2. Mesopic visual acuity measured after dark adaptation (10 minutes in the testing room under mesopic conditions) with the room luminance set to 3 cd/m2	—

Secondary

Measure	Time frame
1. Subjective refraction, performed with the ETDRS chart at 4 meters 2. The defocus curve, performed monocularly with the patients observing the ETDRS chart through lenses starting at -5.00 D and increasing in 0.50 D steps to +3.00 D 3. Binocular contrast sensitivity, measured at spatial frequencies of 3, 6, 12, and 18 cycles per degree (cpd) using the functional acuity contrast test (Test SV-1000) of the CC-100 HW 5.0 Series system 4. Binocular contrast sensitivity after dark adaptation (10 minutes in the testing room under mesopic conditions), measured at spatial frequencies of 3, 6, 12, and 18 cycles per degree (cpd) using the functional acuity contrast test (Test SV-1000) of the CC-100 HW 5.0 Series system 5. Visual function, assessed using Catquest 9-SF questionnaire Measured at 1 month after surgery	—
