如果因屈光不正而需取出或更换以前植入的人工晶状体，对患者来说是一种创伤，它会增加视网膜裂孔、囊样黄斑水肿、睫状体剥离和晶状体后囊或前囊破裂的危险性。如果在原人工晶状体前面再植入一人工晶状体则可以避免上述危险性，而且其屈光度的预测要比行更换人工晶状体手... If the previously implanted intraocular lens needs to be removed or replaced because of refractive errors, it is a trauma to the patient that increases retinal breaks, cystoid macular edema, ciliary body detachment, and the posterior or posterior capsular rupture of the lens Dangerous. If you are in front of the original intraocular lens replantation of an intraocular lens can avoid the above-mentioned risk, and its refractive index prediction than the replacement of intraocular lens ...
