About

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).

Enrollment: 32 patients

Inclusion criteria

1. Subjects must read, understand and sign the Statement of Informed Consent

2. Subjects must be at least 18 years of age

4. Habitual contact lenses must have a suitable fit as determined by the investigator

5. Subjects must report a history of dry eye symptoms, for which they have used rewetting drops or Artificial Tears (ATs) in the past 30 days

7. Subjects must have a score of 12 or higher on the CLDEQ (Contact Lens Dry Eye Questionnaire-8) at baseline

8. Subjects must have at least 2 of the following signs of dry eye disease:

   1. High tear osmolarity > 308 mOsm/L, (milliosmoles per liter) or a difference greater than 8 mOsm/L between eyes
   2. Any corneal staining
   3. Any bulbar conjunctival staining
   4. Low TBUT (tear break up time) (<10s)
   5. Schirmer <10mm in either eye

9. Subjects must be able to read at least half of the 20/25 (via entrance Snellen visual acuity) or better in each eye in their current contact lens prescription.

10. Subjects currently wearing reusable contact lenses must be willing to use Clear Care solution for cleaning and disinfecting throughout the study.

5. Any meibomian gland dysfunction, blepharitis, corneal neovascularization or papillary conjunctivitis that is grade 3 or higher using the Efron Grading Scale.
6. Excessive corneal staining, that in the opinion of the investigator, is a contraindication to contact lens use.
7. History of ocular surgery
8. Any active ocular infection
9. Use of any topical ophthalmic medications other than artificial tears or rewetting drops
