| | Age (years) | (23 to 33) | | Gender (% female) | 54.5% |
| | Spherical equivalent refraction |
| | Manifest (D) | (−3.25 to 0.75) | | Noncycloplegia (D)* | (−3.75 to 0.50) | | Cycloplegia (D)* | (−3.75 to 0.50) |
| | Cylindrical refraction |
| | Manifest (D) | (−0.25 to 0.00) | | Noncycloplegia (D)* | (−0.25 to 0.00) | | Cycloplegia (D)* | (−0.25 to 0.00) | | Ocular HOAs (μm, for a 4-mm pupil) | (0.04 to 0.17) |
