入选标准

  • INCLUSION CRITERIA:
  • Subjects must meet the following inclusion criteria to be eligible for the study eye
  • * Male and female patients, at least 45 years of age
  • * An operable age-related cataract with BCVA of 20/40 or worse, eligible for phacoemulsification; if BCVA is better than 20/40, testing with a BAT meter on a medium setting must result in BCVA 20/40 or worse
  • * A diagnosis of POAG treated with 1 to 4 hypotensive medications
  • * Optic nerve appearance characteristic of glaucoma
  • * Medicated IOP <= 31 mmHg
  • * Diurnal IOP >= 22 mmHg and <= 34 mmHg after wash out of ocular hypotensive medications
  • * IOP increase >= 3 mmHg after wash out of ocular hypotensive medications
  • * Visual field examination using Humphrey 24-2 SITA standard, meeting protocol specified minimum criteria for glaucoma defined as:
  • - Mild: visual field loss on Humphrey visual field testing, with mean deviation (MD) between 0 and -6dB; fewer than 25% of points depressed below the 5% level and fewer than 15% of points depressed below the 1% level on pattern deviation plot; and no point within central 5° with sensitivity <15dB
  • - Moderate: visual field loss on Humphrey visual field testing, with mean deviation worse than -6dB but no worse than -12dB; fewer than 50% of points depressed below the 5% level, and fewer than 25% of points depressed below the 1% level on pattern deviation plot; no points within central 5° with sensitivity of <=0dB; and only one hemifield containing a point with sensitivity <15dB within
  • 5° of fixation
  • * In subjects where the VF exam is not confirmatory for glaucomatous defect, retinal nerve fiber layer optical scanning laser imaging supporting ophthalmoscopy findings shall be performed
  • * Shaffer grade >= III in all four quadrants
  • * Cup:disc (c:d) ratio <= 0.8
  • * Absence of peripheral anterior synechiae (PAS), rubeosis or other angle abnormalities that could impair placement of the implant
  • * Subject is able and willing to attend scheduled follow-up exams for 2 years postoperatively (and up to 5 years postoperatively as part of a post-approval study)
  • * Subject understands and signs the informed consent;INTRAOPERATIVE ELIGIBILITY CRITERIA
  • Individuals who meet the following intraoperative eligibility criteria in the study eye will be randomized into the treatment or control arms of this study.;Subjects must have:
  • * An intact and centered capsulorrhexis
  • * An intact posterior capsular bag
  • * A well-centered monofocal IOL placed in the capsular bag
  • * A clear view of an open angle and visualization of the angle with direct gonioscopy
  • following intracameral instillation of a miotic agent, and;Subjects must not have:
  • * Evidence of zonular dehiscence/rupture
  • * Intraoperative floppy iris syndrome

排除标准

  • EXCLUSION CRITERIA
  • Excluded from the study will be individuals with the following characteristics. Unless specified otherwise, all ocular criteria refer to the study eye only.
  • * Closed angle forms of glaucoma
  • * Congenital or developmental glaucoma
  • * Secondary glaucoma (such as neovascular, uveitic, pseudoexfoliative, pigmentary, lensinduced,
  • steroid-induced, trauma induced, or glaucoma associated with increased episcleral venous pressure)
  • * Use of more than 4 ocular hypotensive medications (combination medications count as two medications)
  • * Previous argon laser trabeculoplasty, trabeculectomy, tube shunts, or any other prior filtration or cilioablative surgery
  • * Prior surgery for an ab-interno or ab-externo device implanted in or through the Schlemm*s Canal
  • * 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%)
  • * Use of oral hypotensive medication for glaucoma for treatment of the fellow eye
  • * Subjects with advanced glaucoma or any subject who presents with an unacceptable risk to the subject of a washout of ocular hypotensive medications
  • * Best corrected visual acuity worse than 20/80 in the fellow eye
  • * A 24-2 SITA Standard Humphrey visual field mean deviation (MD) of worse than -12dB in the fellow eye
  • * Central corneal thickness > 620 microns and < 480 microns
  • * Proliferative diabetic retinopathy
  • * Previous surgery for retinal detachment
  • * Previous corneal surgery or clinically significant corneal dystrophy, e.g., Fuch*s dystrophy (>12 confluent guttae)
  • * Unclear ocular media preventing visualization of the fundus or anterior chamber angle
  • * Degenerative visual disorders such as wet age-related macular degeneration
  • * Clinically significant ocular pathology, other than cataract and glaucoma
  • * Clinically significant ocular inflammation or infection within 6 months prior to screening
  • * Presence of extensive iris processes that obscure visualization of the trabecular meshwork
  • * Unable to discontinue use of blood thinners in accordance with surgeon*s standard postoperative instructions
  • * Known or suspected elevated episcleral venous pressure due to Sturge Weber, nanophthalmos, orbital congestive disease
  • * Uncontrolled systemic disease that in the opinion of the Investigator would put the subject*s health at risk and/or prevent the subject from completing all study visits
  • * Current participation or participation in another investigational drug or device clinical trial (which includes the fellow eye) within the past 30 calendar days
  • * Pregnant or nursing women; or women of child bearing age not using medically acceptable contraceptives
