title: [Long-term follow-up of implantation of foldable silicon posterior lenses].
abstract: BACKGROUND
  Prospective analysis of long-term results after small incision no-stitch phacoemulsification with implantation of foldable silicone IOL.
  
  
  METHODS
  In 100 consecutive patients we implanted through a 3.2 mm incision a STAAR-silicone IOL model AA4203. Uncorrected and best-corrected visual acuity, surgically induced astigmatism and postoperative complications were examined at 1 day, 3 months and 1 year after surgery.
  
  
  RESULTS
  On day 1 postop. 75% of the patients achieved uncorrected visual acuity of 0.5 or more. The mean best corrected visual acuity at day 1 was 0.75 (0.22 SD). The vector analysis of the surgically induced astigmatism does not show any difference between day 1 and 1 year postop. with a mean induced astigmatism of 0.73 dpt. 12 Months after surgery we found 3 cases of cystoid macula edema and 3 cases of clinically significant secondary cataract.
  
  
  CONCLUSIONS
  The clinical long-term results after implantation of foldable silicon-IOL are comparable with the results after implantation of rigid PMMA lenses. The optical rehabilitation is much faster and contributes to lower the costs of modern cataract surgery.
