title: Does the apodized diffractive intraocular lens Acrysof ReSTOR Natural interfere with FDT Matrix perimetry results?
abstract: OBJECTIVE
  To compare the effect of an apodized diffractive intraocular lens (IOL) (Acrysof ReSTOR Natural) and its yellow counterpart (Natural IQ) on frequency doubling technology (FDT) perimetry results.
  
  
  METHODS
  This study included 37 eyes from 22 patients at the 'Centro Oftalmológico Tranjan' who had undergone uncomplicated phacoemulsification and intraocular lens implantation (17 Acrysof ReSTOR Natural, 20 Natural IQ) performed by the same surgeon, at least three months prior to the study. Patients were subject to frequency doubling technology Matrix Perimeter testing.
  
  
  RESULTS
  The patients were between 41 to 79 years old (mean, 70.78 +/- 9.83) in the Natural IQ and 49 to 81 years old (mean, 67.11+/- 11.48) in the Acrysof ReSTOR Natural group, and the mean IOP was 13.64 +/- 2.02 mmHg in the Natural IQ 12.94 +/- 1.39 mmHg in the Acrysof ReSTOR Natural group. The mean pupillary diameter under scotopic conditions was 6.63 +/- 1.16 mm in the Natural IQ group and 7.20 +/- 1.8 mm in the Acrysof ReSTOR Natural group (p=0.20). The mean deviation was -1.83 +/- 3.46 dB in the Natural IQ group and -1.77 +/- 3.94 dB in the Acrysof ReSTOR Natural group (p=0.28). The pattern standard deviation was 3.49 +/- 0.79 dB in the Natural IQ group and 3.20 +/- 0.86 dB in the Acrysof ReSTOR Natural group (p=0.27).
  
  
  CONCLUSIONS
  There was no difference in the results of FDT Matrix perimetry in eyes that received apodized diffractive IOLs implant or eyes that received monofocal intraocular lens implant.
