Combined Phacoemulsification With iStent Inject W Versus Hydrus for Mild to Moderate Open Angle Glaucoma

October 30, 2024 updated by: Diablo Eye Associates

Prospective, Randomized Controlled Study Comparing Combined Phacoemulsification With iStent Inject W Versus Hydrus for Mild to Moderate Open Angle Glaucoma (COMPETE)

The goal of the study is to prospectively evaluate and compare Hydrus microstent to the iStent Inject Wide in combination with cataract surgery in patients with mild to moderate open angle glaucoma. Hydrus and iStent are the two FDA approved trabecular meshwork targeting microstents to treat open angle glaucoma in conjunction with cataract surgery.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

60 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
Percentage of subjects with complete success defined as intraocular pressure reduction > 25% from baseline And without secondary intervention to reduce IOP (medication, laser trabeculoplasty, or surgery) at 24 month.
Time Frame: 24 Months
24 Months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Intraoperative and postoperative adverse events rates
Time Frame: 24 Months
24 Months
Rates of secondary intervention to reduce intraocular pressure
Time Frame: 24 Months
24 Months
Rates of needing incisional glaucoma surgery as secondary intervention to control interocular pressure
Time Frame: 24 Months
24 Months
