[Lens astigmatism in connection with implantation of a foldable one-piece silicone lens in a patient].

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.

CASE REPORT: 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.

CONCLUSION

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.
