title: Visual quality assessment in patients with orange-tinted blue light-filtering and clear ultraviolet light-filtering intraocular lenses.
abstract: OBJECTIVE
  To evaluate potential differences in the quality of vision after implantation of a blue light-filtering intraocular lens (IOL) and an ultraviolet (UV) light-filtering IOL.
  
  
  METHODS
  Department of Ophthalmology, Ruhr-University, Bochum, Germany.
  
  
  METHODS
  Prospective randomized cohort study.
  
  
  METHODS
  Patients with age-related cataract had bilateral standardized small-incision Kelman phacoemulsification-based cataract surgery with implantation of a blue light-filtering IOL (Oculaid PC 440Y Orange Series) in 1 eye and a UV light-filtering IOL (Oculaid PC 430 Elite Series) in the other eye. Outcome measures included scotopic and photopic corrected distance visual acuity (CDVA) and photopic uncorrected distance visual acuity (UDVA), color discrimination, and contrast sensitivity with and without glare. A questionnaire was used to assess patient satisfaction. Postoperative follow-up visits were scheduled at 1, 3, and 6 months.
  
  
  RESULTS
  Twenty-two patients (44 eyes) completed the study. There were no statistically significant differences in UDVA, CDVA, or contrast sensitivity with or without glare between the 2 IOL groups. Color discrimination was significantly decreased in eyes with blue light-filtering IOLs compared with UV light-filtering IOLs, except along the red-green axis (P=.118). No subjective differences in color or light perception were found.
  
  
  CONCLUSIONS
  Both IOL types provided similar postoperative visual function except color perception, which was slightly better in eyes with a clear IOL. Although differences were not clinically significant, information about potential disturbances in color vision might be provided before implanting an orange blue light-filtering IOL.
