Results of Patients With Glaucoma Undergoing Minimally Invasive Glaucoma Surgery in Conjunction With Cataract Surgery

This study is designed to determine how well patients with glaucoma can see following cataract surgery with a special type of lens called an extended-depth-of-focus (EDOF) lens. This lens is intended to reduced the patients need for glasses following cataract surgery. Patients will also undergo a minimally invasive type of glaucoma surgery using a special type of stent to reduce eye pressure, with the goal of better glaucoma control and the reduction in the need for medications to control eye pressure.

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Male or female subjects 45 years of age or older
  • A visually significant age-related cataract in both eyes
  • Diagnosis of mild OAG
  • VF characteristics consistent with glaucoma with mean deviation not worse than -6.00 dB and without fixation threatening scotoma AND/OR with nerve abnormalities consistent with glaucoma (rim notching, rim thinning, disc hemorrhage, nerve fiber layer loss)
  • Medicated IOP ≤25 mmHg on 1-3 hypotensive medications
  • Glaucoma must be judged as stable by investigator based on review of subject medical records

  • Stable nerve fiber layer at least 1 year prior to surgery
  • IOP stable on current medication regimen at least 3 months prior to surgery
  • Shaffer grade of ≥ III in all angle quadrants
  • Potential of best corrected visual acuity at distance in the investigator's judgement of at least 0.1 logMAR (20/25) postoperatively
  • Able and willing to comply with follow up visits
  • Understands and signs the informed consent
  • Both eyes of the subject should undergo surgery within 21 days of each other to ensure adequate timing for final visit window of 90 days ± 21 days post operatively

Exclusion criteria

  • Previous incisional glaucoma surgery or cilio-ablative surgery
  • Prior laser trabeculoplasty within 90 days of surgery
  • Pseudoexfoliative, angle closure, uveitic, congenital, traumatic, angle recession, or neovascular glaucoma.
  • Moderate glaucoma with VF mean deviation between -6.00 dB and -12.00 dB
  • Severe and/or progressive glaucoma defined as
  • VF mean deviation worse than -12.00 dB
  • Consistent worsening of visual field on review of subject medical records
  • Consistent and progressive thinning of nerve fiber layer on review of subject medical records
  • Uncontrolled IOP on maximum glaucoma medications
  • Historically poor IOP control with medical therapy
  • Severe focal notching of the optic nerve rim
  • Expectation for future need of incisional glaucoma surgery
  • Ocular pathology or other medical condition which, in the investigator's judgment places the subject at increased risk of complications or significant vision loss during study period
  • Ocular pathology that in the investigator's judgment may impact visual acuity postoperatively, i.e., significant ocular surface disease, corneal scarring, blepharitis, epiretinal membrane, macular degeneration, history of significant ocular trauma with sequela, etc.
  • Pregnant or breastfeeding women
  • Prior refractive surgery e.g., LASIK, RK, PRK, etc.
  • Subjects with significant complications during surgical procedure e.g., broken capsule, Hydrus Microstent complication, will be exited from the trial
  • Subjects who experience visually significant complications related to the Hydrus Microstent during the study period will be exited from the trial

  6. Quality of Vision Questionnaire (QoV)

    Time frame: 3 months

    The QoV is a validated questionnaire designed to determine what if any visual disturbances are present following surgery. It consists of a 30-item instrument with 10 possible symptoms rated in each of 3 scales (frequency, severity, and bothersome). Examples of common visual disturbances include glare and halo. This outcome measure can be graded on a linear scale with a higher score being a worse outcome (more visual disturbances). This questionnaire takes approximately 5 minutes to complete.

  7. IOL patient satisfaction (IOLSAT) questionnaire

    Time frame: 3 months

    The IOLSAT is a questionnaire inquiring about the need for eyeglasses, vision without eyeglasses, expectations for needed eyeglasses, and visual satisfaction. It consists of 23 questions, the first 21 based on a Likert scale. Questions 22 asks whether the patient would choose the same lens again and 23 if they would recommend the lens to their family and friends.

  8. Mean preoperative IOP versus postoperative IOP

    Time frame: 3 months

    Comparing intraocular pressure before versus after intervention

  9. Mean preoperative medications versus postoperative medications

    Time frame: 3 months

    Comparing the amount of preoperative glaucoma medications before versus after intervention
