title: [Monocentric two-year results after phakic posterior chamber lens (PRL) implantation in myopic patients].
abstract: OBJECTIVE
  Some refractive procedures such as PRK or LASIK are limited by factors, including high myopia, hyperopia, or a thin cornea. For these cases, phakic intraocular lenses have been developed. Previous models have been associated with various complications, however. In order to minimize risks involved, a new phakic posterior chamber lens (PRL, IOLTECH) has been developed. Recent data suggest a considerably lower complication rate. Our two-year results are presented.
  
  
  METHODS
  The implanted lens (PRL) is a very thin foldable lens made of highly refractive silicone. The design allows floating of the lens and avoids contact to the natural lens. It is not fixed in the ciliary sulcus. Up to now, we have implanted this lens into 56 myopic eyes of 31 patients. Preoperative refraction was within a range of -8.5 to -21.25 D (spherical equivalent = S.E). Best corrected preoperative visual acuity was between 0.3 and 1.0. Postoperative follow-up was up to 3.5 years. In this study 44 eyes with at least 2 years follow-up were included.
  
  
  RESULTS
  Postoperative refraction was + 0.25 to - 1.0 D (SE, one patient with intended postoperative myopia). Far visual acuity without correction was 0.4 to 1.25, far visual acuity with best correction was 0.6 to 1.25. Two cataract formations were observed, one lens had to be removed due to repeated decentration.
  
  
  CONCLUSIONS
  The PRL lens seems to be a promising choice for refractive surgery in myopic patients unfit for corneal surgery, although more results, especially long-term follow-ups are needed.
