Brief Summary

The purpose of this study is to examine the effect of Cequa treatment on the accuracy of pre-operative biometry and on corneal higher-order aberrations (HOAs) in cataract patients who have signs of dry eye disease.

Detailed Description

Hypothesis: In patients with dry eye, defined as corneal staining and a reduced tear breakup time, the accuracy of pre-operative biometry and corneal surface HOAs will improve significantly after four weeks of Cequa treatment.

Primary Outcome Measure: Spherical equivalent prediction error of pre-Cequa vs post-Cequa ocular biometry performed for cataract surgery.

Secondary Outcome Measures:

The impact of Cequa treatment on corneal higher order aberrations measured in the central 6 mm of the cornea.

The difference in SPEED questionnaire scores before and 4 weeks after Cequa treatment.

The difference in corneal staining and tear breakup time (TBUT) before and after treatment with Cequa.

Study Groups

Cequa Treatment In Cataract Patients with Dry Eye Disease

Duration of Study Treatment - 4 weeks All patients will receive cyclosporine ophthalmic solution (0.09%) BID in both eyes for 28 days, 1 drop per dose. Dosing will be BID, both eyes, assuming both eyes will eventually undergo cataract surgery. Otherwise, single eye treatment in the operative eye will be permitted.

Eligibility Criteria

Inclusion Criteria

• Patients with planned cataract surgery,
• The presence of 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.

• Minimum Eligible Age: 18 Years
• Eligible Sex: ALL
• Accepts Healthy Volunteers: Yes
