title: Visual outcomes of a trifocal aspheric diffractive intraocular lens with microincision cataract surgery.
abstract: OBJECTIVE
  To evaluate the visual outcomes of patients with a new diffractive trifocal intraocular lens (IOL).
  
  
  METHODS
  A trifocal diffractive Fine Vision IOL (Physiol, Liege, Belgium) was implanted after microincision cataract surgery (MICS) in 40 eyes of 20 patients with bilateral cataract. The monocular and binocular visual performance and the refractive status were assessed, as well as the defocus curve and contrast sensitivity at 1 and 6 months postoperatively.
  
  
  RESULTS
  The monocular visual outcomes (logMAR) at 6 months postoperatively were uncorrected distance visual acuity 0.18 ± 0.13, uncorrected near visual acuity 0.26 ± 0.15, and uncorrected intermediate visual acuity 0.20 ± 0.11. With the best distance correction, the visual outcomes were 0.05 ± 0.06 for corrected distance visual acuity, 0.16 ± 0.13 for distance corrected near visual acuity, and 0.17 ± 0.09 for distance corrected intermediate visual acuity. Binocular defocus curve at 6 months shows a wide range of useful vision with 0.19 ± 0.08 (logMAR) at -1.50 diopter defocus. The monocular contrast sensitivity under scotopic conditions (3 cd/m(2)) was within normal range for a population older than 60 years.
  
  
  CONCLUSIONS
  The trifocal Fine Vision IOL can restore vision at different distances after cataract surgery, specifically intermediate and near vision.
