Patient description: The patient is a 55-year-old man diagnosed with HCV 2 years ago and the recent coinfection with HBV. His past medical history is non-significant. He is on IFN, RBV and direct antiviral drugs for the past 6 months. The patient takes no other medications. His medical records show previous positive HCV RNA tests and a positive enzyme immunoassay for anti-HCV-antibodies. The recent biopsy was negative for hepatocellular carcinoma and was only remarkable for chronic inflammation compatible with a chronic viral hepatitis. There is no evidence of alcoholic liver disease, bleeding from esophageal varices, hemochromatosis, autoimmune hepatitis, or metabolic liver disease. He is an alert male with no acute distress. His BP: 130/75, HR: 90/min and BMI: 27. His abdomen is soft with no ascites or tenderness. The lower extremities are normal with no edema.

Clinical trial eligibility criteria: eligible ages (years): 40.0-85.0,  Glaucoma Open-Angle Primary Cataract General 1. Male and female patients, from 40 to 85 years of age, inclusive. 2. Patient is able and willing to attend scheduled follow-up examinations as per routine care for 2 year post-operatively. 3. Patient is able to understand the information sheet and give informed consent. for the study eye: 4. An operable age-related cataract with BCVA of 6/9 or worse that is eligible for phacoemulsification. 5. A diagnosis of POAG or pigmentary glaucoma treated with hypotensive medications (eye drops for glaucoma). 6. A previously documented unmedicated intraocular pressure of > 21 mmHg (i.e. IOP > 21 mmHg prior to the commencement of glaucoma treatment). 7. An optic nerve appearance characteristic of glaucoma with either: 1. visual field loss (no worse than -12dB) identified on examination using Humphrey 24-2 SITA standard, or 2. (in patients where the VF exam is not confirmatory for glaucomatous defect) OCT retinal nerve fibre layer imaging supporting the ophthalmoscopy findings indicating a diagnosis of mild glaucoma. (If OCT findings are not confirmatory of glaucoma and both the visual field and the OCT are normal, the patient should not be enrolled). 8. Shaffer grade ≥2 in all four quadrants on gonioscopy. 9. Absence of peripheral anterior synechiae (PAS), rubeosis or other angle abnormalities that could impair surgical access to the ciliary processes  Diagnosis of Primary angle closure glaucoma. 2. Any diabetic retinopathy. 3. Previous history of Central Serous Retinopathy or Cystoid Macular Oedema in either eye. 4. Congenital or developmental glaucoma. 5. Secondary glaucoma (such as neovascular, uveitic, pseudoexfoliative, lens-induced, steroid-induced, trauma induced, or glaucoma associated with increased episcleral venous pressure). 6. Previous trabeculectomy, tube shunts, or any other prior subconjunctival filtration or cycloderstructive surgery. 7. Inability to complete a reliable 24-2 SITA Standard Humphrey visual field on the study eye at screening (fixation losses, false positive errors and false negative errors should not be greater than 33%). 8. Patients with advanced glaucoma or any patient where the risk to the patient of a washout of ocular hypotensive medications (eye drops for glaucoma) is assessed as unacceptable (i.e. where there may be a risk of damage to vision if treatment is stopped for the washout). 9. Best corrected visual acuity worse than 6/36 in the fellow eye (i.e. not the eye undergoing the study intervention). 10. A 24-2 SITA Standard Humphrey visual field mean deviation (MD) of worse than -12dB in the study eye. 11. Previous vitreo-retinal surgery. 12. Previous corneal surgery or clinically significant corneal dystrophy, e.g. Fuch's dystrophy (>12 confluent guttae). 13. Unclear ocular media preventing visualization of the fundus or anterior chamber angle. 14. Degenerative visual disorders such as wet age-related macular degeneration. 15. Clinically significant ocular pathology other than cataract and glaucoma. 16. Clinically significant ocular inflammation or infection within 1 month prior to screening. 17. Presence of extensive iris processes that obscure visualization of the trabecular meshwork. 18. Uncontrolled systemic disease that in the opinion of the investigator would put the patient's health at risk and/or prevent the patient from completing all study visits. 19. Current participation or participation within the past 30 calendar days in another investigational drug or device clinical trial (which includes the fellow eye). 20. Pregnant or nursing women, or women of child bearing age planning pregnancy or not using medically acceptable contraceptives. 21. Unwilling or unable to give informed consent/unwilling to accept randomisation. 22. Unwilling or unable to return for scheduled protocol visits. 23. Any not met
