Pre-fitting visual and refractive data
| Variable | Mean (SD) | Median (range) |
|---|---|---|
| Sphere (D) | − 2.64 (1.42) | − 1.37 (− 12.00 to 3.00) |
| Cylinder (D) | − 3.01 (0.65) | − 3.00 (− 6.50 to 0.00) |
| CDVA (logMAR) | 0.23 (0.07) | 0.22 (0.00 to 0.70) |
CDVA = corrected distance visual acuity; D = diopters; logMAR = logarithm of minimal angle of resolution; SD = standard deviation
