摘要

統計121位病人共126隻眼睛，在同一手術者及方法之下，以10-0尼龍(Nylon)線縫合傷口，並以術後縫線拆除，來控制術後散光，並追踪角膜散光變化至一年，結果發現每拆一針可以減少1.54D散光，前4星期自然減少2.38D散光，追踪至一年，不拆線組仍有1.05D減少，拆線組也有平均1.22D減少；此外術後一年仍有散光的變化，且偏向非循例散光；術前若屬於循例性散光者，拆線後易偏向非循例散光。至於角膜弧度何時穩定，尚待更長久的評估。

並列摘要

126 eyes underwent ECCE+PCIOL by the same operator and procedure were studied for suture-cutting effect for astigmatism. We divided the cases into 4 groups according to suture cutting numbers, we found that:
(1) There was 2.38D spontaneous regression one month postoperatively.
(2) One suture cutting produced 1.54D regression effect.
(3) From 8 weeks to one year, more astigmatism reduction was found in suture cutting group than in no suture cutting group.
(4) Progressive regression effect was still present one year after surgery.
(5) Those eyes which had with-the-rule astigmatism before the operation would have more regression response after suture cutting.
