title: Implantation and capsular bag stability of single-piece, foldable EasAcryl 1 intraocular lenses.
abstract: OBJECTIVE
  To assess the folding and implantation of the single-piece EasAcryl 1 intraocular lens (IOL) and the maintenance of the tunnel structure and capsular bag stability after implantation.
  
  
  METHODS
  S. Orsola Hospital Department of Pathophysiologic Optics, University of Bologna, Bologna, Italy.
  
  
  METHODS
  This study comprised 300 cases of EasAcryl 1 IOL implantation. First, a 3.2 mm corneal incision was made according to preoperative astigmatism followed by a 5.5 mm +/- 0.3 (SD) capsulorhexis. After sutureless phacoemulsification using a venturi pump, the 6.0 mm optic, 11.0 mm diameter IOL was implanted using a hexagonal cartridge. The IOLs were implanted using a 2-step maneuver when the superior haptic was grasped with the forceps (first case) or a 1-step maneuver when only the Microsert injector was used. The cartridge was never pushed beyond the tunnel. The preoperative and postoperative incision size and the corneal surgically induced astigmatism were recorded. The IOL rotation was measured 30 +/- 5 days and 8 +/- 1 months postoperatively.
  
  
  RESULTS
  No intraoperative complications occurred after the learning curve. No alteration in astigmatism was observed. The mean IOL rotation was 1.04 +/- 0.5 degrees at 30 +/- 5 days and 1.02 +/- 0.2 degrees at 8 +/- 1 months.
  
  
  CONCLUSIONS
  The EasAcryl 1 was easily implantation through a 3.2 mm tunnel without altering the natural architecture. The unfolding of the IOL was well controlled, and the IOL remained well centered. A short learning curve is required.
