title: [Lens astigmatism in connection with implantation of a foldable one-piece silicone lens in a patient].
abstract: BACKGROUND
  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.
  
  
  METHODS
  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.
  
  
  CONCLUSIONS
  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.
