Base Curve
| Average K (D) | Radius of Curvature (mm) | Suggested SilSoft BC |
|---|---|---|
| ≥ 45.0 D | ≤ 7.50 mm | 7.5 mm (steepest) |
| 43.0–44.9 D | 7.50–7.85 mm | 7.7 mm |
| ≤ 42.9 D | ≥ 7.86 mm | 7.9 mm</strong> (flattest) |
Age-Based Corneal Curvature
- Newborns (0–2 weeks): Mean K ~49 D (r ≈ 6.9 mm), rapidly flattening to ~46 D by 8 weeks and ~44 D by 12 weeks
- 0–2 years: Pooled mean corneal radius is 7.41 mm (~45.5 D), which is steeper than older children
- 2–4 years: Mean K ~43.7 D (r ≈ 7.72 mm), approaching adult values
- By age 3: Corneal curvature generally reaches the adult range (~43–44 D)
