But what is laser eye surgery ?但什么是激光眼科手术 ？

Laser eye surgery clears vision by reshaping the cornea in a non-invasive way-with a laser.激光眼科手术清除视觉的改变角膜的非侵入性的方式，用激光。 There are two well-known types (or brands) of laser eye surgery , LASIK and PRK .有两个著名的类型（或品牌） 的激光眼科手术 ， 手术和手术 。 Both of these surgeries do the same thing, however they differ in their approach.这两项手术做同样的事情，但是他们不同的做法。

The PRK procedure removes the upper layer of the cornea by etching it off with the laser.在手术过程中删除上层角膜的蚀刻它关闭的激光。 The LASIK surgery cuts a flap in the eye to remove the top layer of the cornea.该磨镶术手术削减襟翼的眼睛取消顶端层角膜。 The end result is the same-the cornea is reshaped and changing the way the eye interprets information. Most of the post-operative symptoms are the same, however, there are some minor differences.最终的结果是相同的，角膜是重新塑造和改变了的眼睛解释的信息。大多数手术后的症状是相同的，但是，有一些小的分歧。

While both laser eye surgery procedures are considered low risk and can be done quickly, there are always possible complications when having any surgery performed.虽然激光眼科手术程序，被认为是低风险，可以做到快速，总是有可能出现的并发症时，没有任何手术。

Most patients will deal with some amount of pain or discomfort for a few days. Blurred vision and sensitivity to light are also common and usually clears in the days following surgery although some may find continued symptoms for months and even fewer may find the symptoms are permanent.大多数患者将处理一些数额疼痛或不适几天。视力模糊和敏感性轻也很常见，通常在清除手术后几天虽然有些可能会发现症状持续几个月，甚至更少可能会发现的症状是永久性的。 Other complications (due to scarring) can potentially cause permanent damage to vision, although additional surgery can sometimes correct this.其他并发症（因疤痕）有可能造成永久性的损害视力，但更多的手术有时可以纠正这种情况。

As with all surgeries there is a potential risk of infection.如同所有的手术有可能感染的危险。 It is generally advised to have each eye operated on separately instead of at the same time to reduce the chance of infection in both eyes.人们普遍有建议每个眼睛手术，而不是单独在同一时间，以减少感染的机会在眼前。 Most infections can be cleared with medication, especially if treated right away.大多数感染可以清除的药物，尤其是如果马上处理。

Even with laser eye surgery , it is still possible to continue to need corrective lenses, though you should be able to get by with a weaker prescription.即使激光眼科手术 ，它仍然有可能继续需要矫正视力镜片，但你应该能够得到的一个较弱的处方。 This is due to another complication-under- or overcorrection of vision.这是由于另一并发症下或矫枉过正的远见卓识。 This happens when the laser removes too much or not enough of the cornea to create perfect 20/20 vision.发生这种情况时，激光去除过多或没有足够的角膜创造完美的20/20远景。 Under-corrected vision may be fixed with further surgery, but overcorrected vision is permanent.副矫正视力可能会进一步固定手术，但overcorrected远景是永久性的。

As with every other surgery, you need to be able to have confidence in your surgeon.同所有其他手术，你必须能够有信心在您的外科医生。 If you have any unanswered questions, do some research on your own, speak with your doctor, and continue to ask questions until you are satisfied.如果您有任何悬而未决的问题，做一些研究自己，说与你的医生，并继续发问，直到您满意。
