高度近视做近视眼手术有后遗症吗?高度近视的朋友们在选择近视眼手术时均会担心后遗症的问题。下面我们请天津华夏医院的专家为我们解答一下：</p><p> 什么是高度近视呢？高度近视是指的是近视度数大于600度、伴有眼轴延长、眼底视网膜和脉络膜萎缩性等退行性病变为主要特点的屈光不正。</p><p> 飞秒激光是一种以脉冲形式运转的激光，持续时间非常短，只有几个飞秒（一飞秒就是10的负15次方秒，也就是1/1000万亿秒）。</p><p> 飞秒激光的手术特点：</p><p> 1.大幅降低手术风险飞秒激光在制作角膜瓣时，只产生一些水和气泡推开角膜组织，对组织无损伤，可对同一患处进行多次手术，安全性大大提高。</p><p> 做近视眼手术后遗症2.“全激光”手术，精确度提高百倍，飞秒激光手术是用激光来制作角膜瓣，无须刀片，而常规的准激光手术是用机械性角膜板层刀来制作角膜瓣，对任何患者来说都是更安全的。</p><p> 3.避免医源染。</p><p> 4.视觉质量更高削面更光滑，切削厚度更均匀、更精确，术后快速修复，减少了眩光、相差等。</p><p> 5.扩大了治疗范围对度数高、角膜薄的患者，能更准确保留更多的角膜基质床供激光切削;而且由于飞秒制作角膜瓣不受角膜曲率影响，对于曲率偏高和偏低的患者手术更安全。</p><p> 正因为“飞秒激光”的特性，医学专家已将它作为超精密外科手术刀，用于视力矫正手术，既能减少组织损伤，又不会留下手术后遗症，甚至可对单个细胞动精密手术或者用于基因疗法。</p><p> 所以，高度近视做飞秒激光手术，没有热效应和冲击波，在整个过程中都不会有组织损伤，所以说不会有后遗症的产生。</p></div> <h5 class="post-tags">Tags: <a
