雷射手術後近方視力模糊的可能原因

如果是遠方清楚但近方糢糊有兩個可能(-如果是角膜影響應該遠近都會模糊)


1.調節因素,也許手術所作的度數超過了,造成有一點遠視的


現象,如果剛好調節力又不足就會產生近方模糊的現象,類似


老花眼的情形,年紀越大越可能發生。


2.聚合因素,因為近視眼戴眼鏡在看近物時,會有眼鏡的稜鏡


輔助,眼睛內轉的角度可以小一點。但雷射後,就要回到原本


正常角度,若屬於聚合不足,就會產生近方影像模糊、浮動甚


一不留神就有雙重影像。

  1. Thanks for helping mе to gаin new thоughts аbout computеr ѕystemѕ.
    I alsο hаve thе bеlief that сеrtаin оf the best wаyѕ tο help keеp уour notebook in prime cοndіtion has beеn a hard plastic-type
    cаѕe, oг maуbe shell, which fіtѕ over the top of one's computer. These kind of protective gear are generally model unique since they are made to fit perfectly on the natural outer shell. You can buy these directly from the vendor, or through third party sources if they are readily available for your mobile computer, however not every laptop may have a covering on the market. Yet again, thanks for your tips.
