简要总结
The goal of this clinical trial is to look at the difference in pressure lowering effects in patients having two different combinations of minimally invasive glaucoma surgery (MIGS) at the time of their cataract surgery. Eligible patients will have mild to moderate glaucoma and be candidates for cataract surgery. The trial will look at the eye pressure before and one year after cataract surgery in patients. One eye in each patient will have cataract surgery with canaloplasty using OMNI. The patients other eye will have cataract surgery with canaloplasty and a HYDRUS stent. The trial will look at the differences in eye pressure and if patients are able to need fewer eye pressure lowering drops after surgery.
Study participants will undergo preop testing of pressure, vision, slit lamp exam, ocular coherence tomography (OCT) of the nerve fiber layer (NFL) analysis, and visual field prior to cataract surgery with MIGS. One day, one week, one month, 6 month, and 1 year exams will be performed to check pressure, vision, slit lamp exam, and number of necessary eye pressure medications in each eye.
详细描述
The purpose of this research study is to:
· Determine the differing pressure lowering effects between OMNI canaloplasty alone versus when combined with HYDRUS microstent. Both surgical study devices are widely used by themselves in conjunction with cataract surgery. While many surgeons have begun combining the two procedures, this will be one of the first studies to randomize (assign by chance) one eye to OMNI canaloplasty alone and the other eye to OMNI canaloplasty with HYDRUS stent and report the results after one year.
About 80 subjects aged 18 years and older will participate in this study.
WHAT WILL HAPPEN DURING THE STUDY?
Your participation in this study will last approximately one year and will include approximately seven study visits to the study center and two visits to the surgery center.

入选标准
- •Subjects with bilateral mild to moderate open angle glaucoma:
- •Including pseudoexfoliation (PXE) and pigment dispersion (PDS) According to ICD-10 guidelines and with visual field (VF) mean deviation -12 decibels (dB) or better With visually significant age-related cataract undergoing uncomplicated cataract surgery Able to randomize first eye to either treatment group, contralateral eye to receive other treatment Fairly symmetric glaucoma with cup to disc (C/D) asymmetry ≤ 0.1 and similar OCT RNFL and VF mean deviation IOP ≥ 20 mmHg and ≤ 36 mmHg after washout of ocular hypotensive medication(s); ≤3mmHg between the eyes Central corneal thickness (CCT) 480 to 620µm No prior ocular surgery including corneal refractive surgery; No selective laser trabeculoplasty (SLT) within 3 months of baseline visit, no history of intracameral implants Potential of good best corrected visual acuity at distance in the investigator's judgement of at least 0.1 LogMAR (20/25) postoperatively
排除标准
- •Subjects with secondary glaucoma (traumatic, neovascular, mixed-mechanism, uveitic glaucoma) Uncontrolled intraocular pressure on maximum tolerated medical therapy; unable to wash-out intraocular pressure (IOP) lowering drops Anatomic exclusion of narrow anterior chamber angle (Shaffer grade I-II), other angle abnormalities leading to poor angle visualization H/o corneal disease or dystrophy Pathological myopia with degeneration that affects diagnostic imaging Clinically significant ocular pathology or degenerative diseases that affect vision, humphrey visual field (HVF), or OCT Inability to perform reliable HVF /OCT
