Digital Device Users Who Are Treated With Systane Hydration PF

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.

Extensive computer use is no longer an employment-specific challenge. Use of digital devices in work, home, and leisure settings is now the norm, and it is now socially expected. While the introduction of high-powered computers and digital devices have greatly improved many aspects of modern life, the pervasive use of digital devices has caused some patients to develop a condition known as Digital Eye Strain (DES). DES has been reported to be as high as 93% the population depending upon how the condition is defined, and its severity has been found to increase with increased digital device time. DES is a condition where patients experience symptoms such as glare, accommodative dysfunction, defocus, fatigue, discomfort, and dryness from digital device use, and these dry eye symptoms may also result in decreased quality of life. While dryness symptoms in DES are likely multifactorial (e.g., contact lens use, systemic disease status), much of the dryness symptoms in DES are probably due to tear film evaporation secondary to having a reduced number of blinks per minute while using digital devices. Since much of the ocular symptoms associated with DES stem from excessive tear evaporation, artificial tears have become an accepted DES treatment 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. Systane Hydration PF has HydroBoost technology, which is thought to enhance the drop's effectiveness by incorporating ingredients that increase drop retention. 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.

All subjects will be treated with Systane Hydration PF. Half will start with the unit-dose version and half with start with the multi-dose version. Subjects will switch to the other dosing option in the middle of the study.

Investigators will be masked to the dosage group. Subjects will not be masked because it is not possible with the dosage interventions.

Subjects randomized to this group will apply the unit-dose version of Systane Hydration PF to determine if it helps alleviate symptoms associated with digital eye strain.

Subjects randomized to this group will apply multi-dose version of Systane Hydration PF to determine if it helps alleviate symptoms associated with digital eye strain.

This is an over-the-counter preservative free artificial tear that can be purchased at most retail stores and pharmacies.

Impact of Dry Eye on Daily Life (IDEEL) Work questions will be self-administered electronically to understand how treatment with Systane Hydration PF helps a patient's ability to work (0-100 scale with 100 being worst and 0 being best).

Subjects will report whether they preferred the unit-dose dispensing method or the multi-dose dispensing method via a forced choice questionnaire (forced choice with patient being required to pick if they like the unit-dose dispensing method or the multi-dose better).

The Ocular Surface Disease Index (OSDI) will be self-administered electronically to understand how treatment with Systane Hydration PF helps a patient's ability to work (0-100 scale with 100 being worst and 0 being best).
