Summary:

      Systane Hydration PF is a recently released preservative-free artificial tear that is able to
      supplement the ocular surface's moisture while simultaneously soothing the eye. While Systane
      Hydration PF should in theory improve the symptoms and subsequently the quality of life of
      patients who have DES, this clinical application has yet to be tested. This drop furthermore
      is available in both unit-dose and multi-dose options; however, it is unclear if patient
      perceive a difference between the two dispensing methods. Therefore, the primary purpose of
      this study is to recruit patients who have DES and to treat them with Systane Hydration PF
      and determine how regular use of this drop impacts a patient's ocular surface symptoms and
      overall quality of life. This study will secondarily compare the two dispensing methods to
      determine if patients prefer one method over the other.
