This is a prospective, single site, randomized, double masked, comparator-controlled study designed to evaluate the efficacy of lifitegrast ophthalmic solution 5% in treating the symptoms of dry eye in soft contact lens wearers as compared to control. We hypothesize that there will be a significant improvement in dry eye symptoms in contact lens wearers using lifitegrast as compared to those being treated with control (lifitegrast vehicle).

Efficacy of Lifitegrast Ophthalmic Solution 5% in Treating the Symptoms of Dry Eye in Contact Lens Wearers as Measured by Change in Total CLDEQ-8 Score From Baseline to Week 8
Measured by change in total score on the CLDEQ-8 (Contact Lens Dry Eye Questionnaire) in subjects using lifitegrast ophthalmic solution as compared to subjects using lifitegrast ophthalmic solution vehicle from baseline to week 8. The CLDEQ-8 (Contact Lens Dry Eye Questionnaire) is a symptom questionnaire that assesses discomfort related to dry eye in contact lens wearers. The minimum possible CLDEQ-8 score is 0. The maximum possible CLDEQ-8 score is 37. Therefore, the maximum change is +/- 37. A negative change is an improvement in symptoms (a lower score at week 8 than baseline).
Time frame: 8 weeks
Change in Total Score on the CLDEQ- 8 From Baseline to 2 Weeks
Measured by change in total score on the CLDEQ-8 (Contact Lens Dry Eye Questionnaire) in subjects using lifitegrast ophthalmic solution as compared to subjects using lifitegrast ophthalmic solution vehicle from baseline to week 2. The CLDEQ-8 (Contact Lens Dry Eye Questionnaire) is a symptom questionnaire that assesses discomfort related to dry eye in contact lens wearers. The minimum possible CLDEQ-8 score is 0. The maximum possible CLDEQ-8 score is 37. Therefore, the maximum change is +/- 37. A negative change is an improvement in symptoms (a lower score at week 2 than baseline).
Time frame: 2 weeks
Change in Total Score on the CLDEQ- 8 From Baseline to 4 Weeks
Measured by change in total score on the CLDEQ-8 (Contact Lens Dry Eye Questionnaire) in subjects using lifitegrast ophthalmic solution as compared to subjects using lifitegrast ophthalmic solution vehicle from baseline to week 4. The CLDEQ-8 (Contact Lens Dry Eye Questionnaire) is a symptom questionnaire that assesses discomfort related to dry eye in contact lens wearers. The minimum possible CLDEQ-8 score is 0. The maximum possible CLDEQ-8 score is 37. Therefore, the maximum change is +/- 37. A negative change is an improvement in symptoms (a lower score at week 4 than baseline).
Time frame: 4 weeks

Change in Tear Osmolarity OD (Right Eye) From Baseline to Week 8
Change in tear osmolarity (as measured by the TearLab device) from baseline to week 8 in the lifitegrast 5% group compared to subjects using lifitegrast ophthalmic solution vehicle. Measured in mOsm/L. A negative change is a lower osmolarity at week 8, which would be an improvement.
Time frame: 8 weeks
Change in Tear Osmolarity OS (Left Eye) From Baseline to Week 8
Change in tear osmolarity (as measured by the TearLab device) from baseline to week 8 in the lifitegrast 5% group compared to subjects using lifitegrast ophthalmic solution vehicle. Measured in mOsm/L. A negative change is a lower osmolarity at week 8, which would be an improvement.
Time frame: 8 weeks
Forced Choice Questionnaire
Forced choice questionnaire asking if the participant felt that their symptoms improved to the point that they would continue treatment outside of the study
Time frame: 8 weeks
Change in Score for Each Question on the CLDEQ-8 From Baseline to Week 8
Measured by change in score for each Contact Lens Dry Eye Questionnaire-8 (CLDEQ-8) question in subjects using lifitegrast ophthalmic solution compared to subjects using lifitegrast ophthalmic solution vehicle. A negative change for a question from baseline to week 8 is an improvement in symptom frequency or intensity. Questions are for the past 2 weeks. Questions 1a, 2a, 3a \& 4 ask about frequency of eye discomfort when wearing contacts, eye dryness, changeable, blurry vision in contacts and wanting to close your eyes. Scale: 0=Never, 1=Rarely, 2=Sometimes, 3=Frequently, 4=Constantly Questions 1b, 2b \& 3b ask about the intensity of symptoms at the end of contact lens wearing time noted for questions 1a, 2a and 3a. Scale: 0-5, 0=Never have it, 5=Very Intense Question 5 asks how often did your eyes bother you so much that you felt you needed to take out your contact lenses. Scale: 1=Never, 2=Less than once a week, 3=Weekly, 4=Several times a week, 5=Daily, 6=Several times a day
Time frame: 8 weeks
