The use of one-piece plate-haptic Silicon lenses has become more frequent especially in combination with small incision cataract surgery. Different complications as before are to be expected.
Six weeks after cataract surgery and implantation of a one-piece plate-haptic Silicon lens a lens astigmatism of 3.5 dpt was noted. The astigmatism occurred after successfully performed retinal detachment surgery in this eye. The development of the astigmatism was considered to be due to a capsular shrinkage of the anterior capsular ring. The retinal detachment surgery was performed with the use of SF6 gas, which is known as a factor for increasing inflammation. After a Nd: YAG incision of the anterior capsule the astigmatism disappeared immediately.
Capsular shrinkage can induce a significant lens astigmatism in combination with soft one-piece plate-haptic Silicon lenses. Intraocular inflammation seems to play an important role. Astigmatism after implantation of one-piece plate-haptic Silicon lenses in combination with signs of capsular shrinkage can be explained by lens astigmatism only.
一体式板袢硅胶人工晶状体的使用越来越频繁,尤其是在与小切口白内障手术联合应用时。预计会出现与以往不同的并发症。
白内障手术联合植入一体式板袢硅胶人工晶状体六周后,发现晶状体散光为3.5屈光度。该眼在成功进行视网膜脱离手术后出现了散光。散光的发生被认为是由于前囊环的囊膜收缩所致。视网膜脱离手术使用了SF6气体,已知该气体是炎症加重的一个因素。在前囊进行Nd:YAG切开后,散光立即消失。
囊膜收缩与软性一体式板袢硅胶人工晶状体联合使用时可诱发明显的晶状体散光。眼内炎症似乎起重要作用。一体式板袢硅胶人工晶状体植入后出现散光并伴有囊膜收缩迹象,仅用晶状体散光即可解释。
