title: [Clinical Results of Diffractive Multifocal Intraocular Lens Implantation after Laser In Situ Keratomileusis].
abstract: OBJECTIVE
  To evaluate the visual performance in eyes with diffractive intraocular lenses (IOLs) after laser in situ keratomileusis (LASIK).
  
  
  METHODS
  This single-center retrospective study evaluated eyes that had diffractive multifocal IOL implantation after previous LASIK or not treated with LASIK (controls). The outcomes' measures were the visual acuities (VAs) at distance and near, spherical equivalent (SE) and contrast sensitivity at one month postoperatively.
  
  
  RESULTS
  The study evaluated 40 eyes of 33 patients. The mean uncorrected logMAR VAs were -0.05 ± 0.13/0.00 ± 0.14 (LASIK group/control group) at distance and 0.10 ± 0.13/0.16 ± 0.18 at near. There was no statistically significant difference between the 2 groups at the VAs. The SE of the LASIK group was -0.06 ± 0.39 D, significantly lower than the control group (0.22 ± 0.45 D) (p < 0.05). The contrast sensitivity of the LASIK group at high spatial frequency was lower than the control group (p < 0.05).
  
  
  CONCLUSIONS
  After LASIK, the diffractive multifocal IOL provided good uncorrected distance and near VAs. However, decrease in contrast sensitivity should be considered.
