Evaluation of Extended Tear Film Break Up Time (TFBUT) With an Ocular Emulsion
- Conditions
- Dry Eye
- Interventions
- Other: Systane Balance Lubricating Eye DropsOther: OPTIVE™
- Registration Number
- NCT01368198
- Lead Sponsor
- Alcon Research
- Brief Summary
The primary objective of this investigation will be to quantify the increase in tear film break-up time (TFBUT) associated with the instillation of a single eyedrop of an Ocular Emulsion in dry eye sufferers.
- Detailed Description
The secondary objective of this investigation will be to compare the tear film break up time measured with two different techniques.

-
The subject must not have used any topical ocular drops for approximately 24 hours prior to the enrolment/screening visit
-
The subject must be classified as dry eye at enrolment/screening visit according to the following criteria:
- Subjects' self-assessment of dry eye status (answer of at least "some of the time" to the question, "How often have your eyes felt dry enough to want to use eye drops?");
- TFBUT measured with DET ≤ 5 seconds in at least one eye;
- Grade 1 for meibomian gland expression in both eyes;
- Evidence of missing meibomian glands in both eyes.
- History or evidence of ocular or intraocular surgery in either eye within the past six months.
- History or evidence of serious ocular trauma in either eye within the past six months.
- Current punctal occlusion of any type (e.g., collagen plugs, silicone plugs).
- History or evidence of epithelial herpes simplex keratitis (dendritic keratitis); vaccinia; active or recent varicella viral disease of the cornea and/or conjunctiva; chronic bacterial disease of the cornea and/or conjunctiva and/or eyelids; mycobacterial infection of the eye; and/or fungal disease of the eye.
- Use of any concomitant topical ocular medications during the study period.
- Ocular conditions such as conjunctival infections, iritis, or any other ocular condition that may preclude the safe administration of either drop under investigation.
- Participation in an investigational drug or device study within 30 days of entering this study.
