Result The total root mean square values were significantly related to the refractive power in diopters (P＜0.05), and the aberrations of trefoil, coma and sperical increased with an increase of the astigmatism power.

结果 眼球总RMS值与屈光度呈正相关（P＜0.05），随散光度的增加，高阶像差中的三叶散光、慧差、球差都增加（P＜0.05）。

If you are in a 60mm thickness you still need a very complicated support to avoiding astigmatism but you add the problem of slow heat balance and heavy weight of mirror.

如果你用60MM厚你仍需要非常复杂的支撑以免出现散光，但这样做增加了热平衡的时间和主镜重量。
