Cequa's Onset of Action Trial: an Investigation of CEQUA's Speed of Onset in Improving Ocular Surface Health in Dry Eye Patients

The purpose of this study is to examine the speed of onset of CEQUA ™ in improving the ocular surface among patients with dry eye.

Inclusion Criteria:

*Patients with the following signs: Central or inferior corneal fluorescein staining defined by the Oxford Scale Reduced tear break up time (TBUT) ≤ 10 seconds.

• Able to comprehend and sign a statement of informed consent.
• Willing and able to complete all required postoperative visits.

Exclusion Criteria:

• Ocular surgery (e.g., intraocular, oculoplastic, corneal, or refractive surgical procedure) performed within the last 3 months or at any time that in the investigator's clinical judgment if it would interfere with the outcome measures of this study.
• Clinically significant ocular trauma.
• Active ocular Herpes simplex or Herpes Zoster infection
• Ocular inflammation (uveitis, iritis, scleritis, episcleritis, keratitis, conjunctivitis) at the discretion of the investigator.
• Ocular infection (e.g., viral, bacterial, mycobacterial, protozoan, or fungal infection or the cornea, conjunctiva, lacrimal gland, lacrimal sac or eyelids including hordeolum/stye).
• Active, systemic, or local disease condition that causes clinically significant ocular surface irritation such that it could interfere with the study findings.
• Moderate to severe (Grade 2-4) allergic, vernal or giant papillary conjunctivitis.
• Severe (Grade 3 or 4) inflammation of the eyelid (e.g., blepharochalasis, staphylococcal blepharitis or seborrheic blepharitis)
• Eyelid abnormalities that significantly affect the lid function (e.g., entropion, ectropion, tumor, edema, blepharospasm, lagophthalmos, severe trichiasis, severe ptosis).
• Ocular surface abnormality that may compromise the corneal integrity (e.g., prior chemical burn, recurrent corneal erosion, corneal epithelial defect, Grade 3 corneal fluorescein staining, map dot fingerprint dystrophy, or the effect of any other ophthalmic medication that might in the opinion of the investigator compromise the ocular surface integrity).
• Participation in this trial in the same patient's fellow eye
• Patients who are under age 18, pregnant or breastfeeding, or who may become pregnant during participation in the study.
