Figure 2
Plots of Rs and Rt for varying degrees of collimation. (a) The sagittal radius undergoes a variation ΔRs ≃ 50 mm (either in a single-step or a multi-step motion), while (b) the tangential radius remains unaffected. This adjustment is reversible and allows for the removal of astigmatism by equalizing Rs and Rt. In (c) and (d) Rs remains constant as Rt is varied by an amount ΔRt = −25 m. However, Rs exhibits a consistent variation (ΔRs ≃ 100 m) when Rt is further varied by an amount ΔRt ≃ −13 m (from Rt ≃ −25 m to Rt = −38 m). A similar situation is observed for very large wavefront radii in panels (e) and (f), where the controlled variation in the sagittal direction (ΔRs ≃ 600 m) induces a variation in the tangential direction (ΔRt ≃ −20 m). In addition, a subsequent step back in the sagittal direction (ΔRs ≃ −150 m) does not correspond to a similar change in the tangential direction. This indicates that the process is not entirely reversible. |
