Effect of Cequa Treatment on Accuracy of Pre-operative Biometry & Higher Order Aberrations in Dry Eye Patients Undergoing Cataract Surgery
Completed · Phase 4
Conditions studied: Dry Eye Syndromes
In brief
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.

Who can join
Age: 18 and older. Sex: any. Healthy volunteers: accepted.
You may qualify if…
- 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.
You may not qualify if…
- 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.
