Design outcomes

Primary

Measure	Time frame
1. Evaluation of anterior and posterior segments of the eyeball with slit lamp biomicroscope 2. Examination of uncorrected distance visual acuity (UCDVA) and best distance corrected visual acuity (BDCVA) (logarithm of the minimum angle of resolution [LogMAR] and Snellen's chart) 3. Examination of uncorrected near visual acuity (UNVA) and best distance corrected near visual acuity (BDCNA) (Jaeger reading chart) 4. Axial length 5. Intraocular pressure 6. Measurement of corneal endothelial cell density 7. Contrast sensitivity measurement with CSV-1000 test (Vector Vision) 8. Evaluation of pupil size 9. Measurement of eye aberration with aberrometer WASCA (Carl Zeiss, Inc.) The primary outcomes were measured 1 day, 1 week, 1, 3 and 6 months after surgery.	—
