三焦点人工晶体的优缺点 尹连荣 中国中医科学院眼科医院

三焦点人工晶体的优缺点 尹连荣 中国中医科学院眼科医院 三焦点人工晶体相对于七大晶体来说，它能够提供，远、中、近三个焦点这是它最大的优势，它的远就是指的是5米的距离，中就是指的80厘米的距离，近就是指的是40厘米的距离。同时因为三焦点晶体，它是一个多焦晶体，就像我们多焦眼镜一样，它也有一定的缺点。一就是说术后需要患者，有一个适应的过程，所以患者要对这个三焦点，有一个合理的预期，因为这个三焦点是远、中、近，三个距离的定点很清楚，但并不是说像我们自己眼睛似的从远到近无极变速的，每一点都是聚焦的，它只是这三个点聚焦，而这在这三点的周围，他的视力能看见，但是没有聚焦那么清晰，这一点我们患者要有一个合理的预期。另外一个术后要有一个适应的过程，这是第一个缺点。它第二个缺点就是它的价格要比较贵，那么它相对于其他晶体来说，它的价格是目前最贵的，一枚晶体大概是26800块钱。 Advantages and disadvantages of three focus intraocular lens Compared with the seven major crystals, the three focus intraocular lens, It can provide, This is its biggest advantage, Its distance refers to a distance of 5 meters, Middle is the distance of 80cm, Proximity means a distance of 40 cm. At the same time, because of the three focus crystal, It's a multifocal crystal, Just like our multifocal glasses, It also has some disadvantages. One is that patients are needed after surgery, There's a process of adaptation, So patients need to focus on these three points, There is a reasonable expectation, Because the three focuses are far, medium and near, The three distance points are clear, But it's not like our own eyes are infinitely changing from far to near, Every point is focused, It's just these three points, And that's around these three points, He can see, But it's not as focused, At this point, our patients should have a reasonable expectation. There is another process of adaptation, This is the first drawback. Its second disadvantage is that its price is more expensive, So compared with other crystals, Its price is the most expensive at present, A crystal is about 26800 yuan.
