Perhaps in the eyes acetify on some astigmatism, and this appears to have no major advantages that some lots still much to do.───也许，专注得眼睛发酸，有些散光，这才发现有些看来并无特大优势的地段，仍大有文章可做。
With such a constitution, decentering of the objective lens and the coma corrector does not occur, and hence astigmatism does not occur.───这种结构，*会发生物镜与彗差校*器的偏心，从而*会发生象散。
Currently PRK can only be used to correct myopia and astigmatism, but hypermetropia may also be corrected by PRK in the near future.───目前手术只能用于纠正近视及散光，但也可能是远视矫正手术在不久的将来。
