Two hundred consecutive patients had extracapsular cataract surgery by capsulorhexis and viscoexpression. Capsulorhexis, attempted in 195 eyes, was successful in 87.7%. Viscoexpression was attempted in 162 cases and successfully delivered the nucleus in 87.7%. There were five cases of zonule rupture, one of posterior capsule rupture, and two of vitreous loss. If the capsulorhexis is larger than 5 mm, viscoexpression can be safely used on all cataracts, regardless of nuclear density, and is the ideal transition to phacoemulsification.
200例连续患者接受了通过撕囊和粘弹剂挤压法进行的囊外白内障手术。在195眼中尝试进行撕囊，成功率为87.7%。在162例中尝试进行粘弹剂挤压法，成功娩出晶状体核的比例为87.7%。有5例发生悬韧带断裂，1例发生后囊破裂，2例发生玻璃体脱出。如果撕囊口大于5mm，无论晶状体核密度如何，粘弹剂挤压法可安全用于所有白内障，并且是向超声乳化术过渡的理想方法。
