About this trial

This is an interventional prevention trial for Glaucoma Eye

Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Male or female
  2. Aged ≥ 18 and ≤ 80 years on screening day
  3. Concealment of glaucoma tube shunt or suture tags is indicated
  4. Patients with viable and intact conjunctiva
  5. Candidates must have the ability and willingness to provide a written informed consent, attend all scheduled visits and comply with study procedures
  6. Adequate tear film and lid function as indicated by Tear Film Breakup Time test - more than 5 seconds
  7. Visual acuity of light perception or better
  8. Female patients of childbearing age must agree to use an acceptable and effective method of contraception throughout the study, including the follow-up period, and have negative pregnancy test at screening.

Exclusion Criteria:

  1. Current retinal detachment
  2. Active ocular or orbital infection
  3. History or evidence of severe inflammatory eye diseases (i.e. uveitis, retinitis, scleritis) in one or both eyes within 6 months prior to planned implantation
  4. History of ocular or periocular malignancy
  5. History of extensive keloid formation
  6. Any known intolerance or hypersensitivity to topical anesthetics, mydriatics, or component of the device, specifically Oxybuprocaine hydrochloride, lidocaine, tropicamide, epinephrine, Iodine solution & aromatic polycarbonate urethane
  7. Signs of current infection, including fever and current treatment with antibiotics
  8. Severe generalized disease that results in a life expectancy shorter than a year
  9. Any clinical evidence that the investigator feels would place the subject at increased risk with the placement of the device
  10. Pregnant or breastfeeding female subjects
  11. Participation in any study involving an investigational drug or device within 30 days of the study or 5 half-lives of the drug (whichever longer) or ongoing participation in a study with an investigational drug or device
  12. Any traumatic perforation of the globe OR tissue gaps/weaknesses, resulting either from traumatic, disease- related or iatrogenic damage OR loss of scleral integrity where use of tissue or substitutes is indicated
  13. Vulnerable populations
  14. Active drug or alcohol abuse or dependence that, in the opinion of the principle investigator, would interfere with adherence to study requirements
  15. Subjects with other concurrent severe and/or uncontrolled medical condition which could compromise participation in the study (e.g. active infection, uncontrolled diabetes, uncontrolled hypertension, congestive heart failure, unstable angina, ventricular arrhythmias, active ischemic heart disease, myocardial infarction within six months, uncompensated cirrhosis, active upper GI tract ulceration, active inflammatory disease, malignancy under active treatment)
  16. Subjects who receive anti-coagulation treatment which cannot be interfered during the perioperative period
  17. Hemoglobin A1C (HbA1c) higher than 8% at screening indicating unbalanced diabetes and/or target organ damage associated with diabetes
  18. Subjects receiving chronic systemic immunosuppressants (e.g. steroids, cyclosporine etc.)

Arms of the Study

Arm 1

Arm Type

Experimental

Arm Label

Corneat EverPatch - Synthetic Tissue Substitute for Covering Ophthalmic Implants

Arm Description

Outcomes

Primary Outcome Measures

Safety Assessment
The frequency of all Unanticipated Adverse Device-related Events (UADE) during and following implantation will be recorded

Secondary Outcome Measures

Performance Assessment
Tube or suture exposure will be detected by slit-lamp Biomicroscopy throughout the entire follow up period and incidence will be calculated. Prevention of tube or suture exposure associated with conjunctival erosion and graft melting should be demonstrated in at least 90% of the patients.

5. Study Description

Brief Summary
This clinical trial will assess the clinical safety and performance of the CorNeat EverPatch device used as a tissue substitute for concealment of artificial ocular implants.
Detailed Description
A single arm, pivotal, open label, multi-centre clinical investigation to evaluate the clinical safety and performance of the CorNeat EverPatch, a synthetic tissue substitute for concealment of artificial ocular implants. Subjects will sign a consent form and will be assessed for eligibility based on clinical examinations and medical history. Upon eligibility verification, subjects will be implanted with the investigational device as part of an ophthalmic surgery in which a concealment of an artificial implant is required. Clinical examinations at follow up will include slit lamp biomicroscopy, assessment of visual acuity and intra ocular pressure, and recording of concomitant medications and any safety issues. Follow up visits will be performed at 1 week, 1-, 2-, 3-, 6-, 9- and 12-months post-op.
