The incidence and time of onset of posterior capsular opacification in a consecutive series of 147 silicone lens implants and in 585 polymethylmethacrylate (PMMA) lens implants were compared. Silicone lenses, sulcus and capsular bag fixated, had an opacification rate of 27.9%, while PMMA had a rate of 7.0%. In the silicone lens series, 65.9% of the opaque capsules required YAG laser posterior capsulotomies in the first four months. In the PMMA implants, only 28.6% required YAG laser capsulotomies in the first four months. The mean follow-up time was nine months. Management of capsular opacification in silicone lenses required early YAG laser capsulotomy, with focusing posterior to the capsule to avoid pitting the implant.
对连续的147例硅酮晶状体植入术和585例聚甲基丙烯酸甲酯（PMMA）晶状体植入术患者后囊膜混浊的发生率及发病时间进行了比较。硅酮晶状体采用沟内和囊袋内固定，混浊率为27.9%，而PMMA晶状体的混浊率为7.0%。在硅酮晶状体组中，65.9%的混浊囊膜在前四个月需要进行YAG激光后囊切开术。在PMMA植入组中，前四个月只有28.6%需要进行YAG激光囊切开术。平均随访时间为九个月。硅酮晶状体后囊膜混浊的处理需要早期进行YAG激光后囊切开术，聚焦于囊膜后方以避免植入物出现凹痕。
