Patient description: 19 yo Hispanic female G1P1 at 32+ 6 weeks of gestational age presented to the OB clinic for routine follow up complaining of mild headache and leg swelling. Primary evaluation revealed BP of 146/99 and urine dipstick with 3+ proteins. Her BP and U/A were normal in previous visit. Repeat BP a few hours later is 150/100 mmHg. Laboratory studies showed a normal hematocrit, platelet count, and liver transaminase levels. She is complaining of fatigue but no fever or chills. She is also suffering of headaches with no vision changes. No shortness of breath, cough, chest pain, orthopnea and palpitations or skin rash were observed. Her physical exam was negative for abdominal pain, change in bowel habits, nausea, vomiting, dysuria, frequency, hematuria or frothy urine. Leg swelling was observed with no arthralgia or back pain. She has no specific past medical issues and only uses prenatal vitamins. Her family history is positive for DM type 2 and HTN. She is a social alcohol consumer with the negative history of smoking or drug use. She is only have one partner in past 2 years and didn't have any contraceptive methods since 2 years ago.

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
