Table 2.
Data are mean ± s.e.m. accommodative posterior movement of the posterior lens pole for each age group in human eyes. The amount of posterior lens pole movement was obtained for each eye by calculating the distance change between the posterior lens pole and the central cornea (Fig. 2) in the accommodated state minus unaccommodated state.
| Human Lens Accommodative Posterior Pole Movement | ||||
|---|---|---|---|---|
| Accommodation* (Dioptres) | Mean Posterior | |||
| Adult Age | Movement ± s.e.m. (mm) | n | ||
| 12.2 ±1.2* | Young (19–23 yr) | 0.08 ± 0.01 | 4 | p = 0.02 |
| 8.5 ±0.9* | Mature (27–31 yr) | 0.01 ± 0.03 | 4 | p = 0.78 |
| 1.0 ±0.5* | Older (49–65 yr) | −0.08 ± 0.04 | 4 | p = 0.14 |
