title: Systane® ultra lubricant eye drops for treatment of contact lens-related dryness.
abstract: OBJECTIVE
  To assess the clinical performance of Systane Ultra lubricant eye drops in daily disposable soft contact lens wearers who experience contact lens-related dryness.
  
  
  METHODS
  In this randomized, investigator-masked study, daily disposable lens wearers with symptoms of dryness were randomized to use Systane Ultra lubricant eye drops or to no treatment. The lubricant regimen was applied twice a day, 10 minutes before lens insertion and after lens removal, for the 2-week study period. Subjective comfort, wear time, and visual acuity were assessed at baseline and after 2 weeks.
  
  
  RESULTS
  A total of 89 daily disposable lens wearers were randomly assigned to the Systane Ultra group (n=44) or the control group (n=45). Two weeks of Systane Ultra lubricant eye drop use resulted in a significant increase in comfortable lens wear time when compared with baseline assessment (P=0.001) and a trend toward significant improvement compared with the control group (P=0.078). End-of-the-day comfort was significantly improved in the Systane Ultra group compared with the control group (P=0.007). A significant reduction in the overall dryness (P<0.001) and end-of-day dryness (P=0.047) was observed in subjects using the Systane Ultra lubricant eye drops compared with the control group.
  
  
  CONCLUSIONS
  The study demonstrates that Systane Ultra lubricant eye drops applied before and after contact lens wear is an effective artificial tear for alleviating symptoms of contact lens-related dry eye.
