title: Primary piggyback implantation using the ReSTOR intraocular lens: case series.
abstract: OBJECTIVE
  To assess the postoperative outcomes of piggyback implantation using the AcrySof ReSTOR intraocular lens (IOL) (model SA60D3, Alcon Surgical Laboratories).
  
  
  METHODS
  Hospital Oftalmológico de Brasília, Brasília, Brazil.
  
  
  METHODS
  Thirteen eyes of 7 patients who had phacoemulsification with piggyback IOL implantation were analyzed prospectively. In all cases, a ReSTOR IOL was implanted in the capsular bag and a second silicone IOL was implanted in the ciliary sulcus. Information collected included uncorrected visual acuity (UCVA) at near and distance, best corrected visual acuity (BCVA), and spherical equivalent (SE) before and after surgery.
  
  
  RESULTS
  The patients were followed for 12 months. The mean distance UCVA was 0.25 (20/80) preoperatively and 0.88 (20/23) at the last follow-up (1 year), which was significantly better than before surgery (P<.05). The mean SE was +4.25 diopters (D) +/- 1.5 (SD) preoperatively and +0.15 +/- 0.44 D (range -0.50 to +0.75 D) at 1 year, which was significantly better than preoperatively (P<.05). No patient lost lines of BCVA after surgery. At the last follow-up, all eyes had a near UCVA of J1 and none required spectacles for near or distance vision.
  
  
  CONCLUSIONS
  Piggyback implantation using the ReSTOR IOL appeared to be a safe and efficient procedure providing high-quality visual acuity for near and distance vision in selected patients.
