title: Performance of presbyopia-correcting intraocular lenses in distance optical bench tests.
abstract: OBJECTIVE
  To compare the optical performance of 6 presbyopia-correcting intraocular lenses (IOLs) of different designs (accommodating or multifocal and aspheric or spheric).
  
  
  METHODS
  Alcon Laboratories, Inc., Fort Worth, Texas, USA.
  
  
  METHODS
  The optical performance of 6 IOLs were compared using modulation transfer function (MTF) and the United States Air Force 1951 Resolution Target (AFT) testing. The IOLs included 3 spheric designs (Crystalens AT-50SE, AcrySof ReSTOR SA60D3, and ReZoom NXG1) and 3 aspheric designs (AcrySof ReSTOR SN6AD3, Acri.Lisa 366D, and Tecnis ZM900). Tests were performed with a modified International Organization for Standardization (ISO) model eye with a 5.0 mm aperture at the distance focus.
  
  
  RESULTS
  The ReSTOR aspheric IOL had the highest MTF values at all spatial frequencies, and the ReZoom IOL had the lowest MTF values at most spatial frequencies. The ReSTOR aspheric IOL produced the image with the highest resolution on the AFT test; the Tecnis and the ReZoom IOLs produced the images with the poorest resolution. The Acri.Lisa multifocal IOL was second to the ReSTOR aspheric IOL on the MTF test and had high resolution on the AFT test. The accommodating Crystalens performed poorly on the MTF test but had the second highest resolution on the AFT test.
  
  
  CONCLUSIONS
  The AcrySof ReSTOR SN6AD3 aspheric IOL showed superior optical properties, demonstrated in MTF and AFT optical bench testing, among 6 presbyopia-correcting IOLs including the monofocal accommodating Crystalens. The Acri.Lisa IOL also performed well. The ReZoom IOL demonstrated the poorest overall optical quality.
