title: Postoperative decentration of three-piece silicone intraocular lenses.
abstract: OBJECTIVE
  To compare the postoperative decentration of three-piece silicone intraocular lenses (IOLs) with polymide haptics and with polypropylene (PP) haptics and to determine whether the difference was caused by the haptic material.
  
  
  METHODS
  Kimura Eye and Internal Medicine Hospital and Hitani Eye Clinic, Hiroshima, Japan.
  
  
  METHODS
  Using a previously described photographic method, we calculated the postoperative decentration in randomly selected patients who had phacoemulsification and capsular bag implantation of three-piece silicone IOLs. In 64 patients, the IOL had polyimide haptics and in 57, PP haptics. One surgeon performed all the surgery using the same technique.
  
  
  RESULTS
  Mean decentration of IOLs with polyimide haptics was 0.34 mm +/- 0.17 (SD) and of those with PP haptics, 0.48 +/- 0.30 mm. Although follow-up of the polyimide group was longer than that of the PP group (12.8 +/- 5.7 months and 8.7 +/- 4.0 months, respectively), decentration in the polyimide group was significantly smaller (P < .01).
  
  
  CONCLUSIONS
  The lower rate of postoperative decentration in the IOLs with polyimide haptics was related to the haptic material.
