GLAUKOS TRAVOPROST INTRAOCULAR IMPLANT CLINICAL STUDY

(not actual size)

About the study…

The purpose of this clinical study is to evaluate the intraocular pressure (IOP)-lowering effect of two investigational implanted medication treatments, as compared to a control topical medication treatment.  It is designed to compare the results from three different groups of patients.  All three groups will receive treatment.  One group will receive the fast-releasing implant and drops, a second group will receive the slow-releasing implant and drops, and the third group will undergo a pretend surgery, (meaning the motions of a surgery will take place in the operating room but no surgery will take place) and receive only drops.

Will I receive the implant?

By participating in the clinical study, you will have a 100% chance of being treated with a medication, 2 in 3 chance (66%) of receiving the Travoprost Intraocular Implant and a 1 in 3 chance (33%) of receiving Timolol drops.  The study will require all patients to use a drop 2 times a day for the duration of the study.  The type of drop will be predicated by which arm of the study to which you are randomized.

Will the patient know if they got the implant?

Subjects will not know which treatment they are receiving until after the study is complete.  This is common practice in a clinical study to prevent or minimize the chance that knowledge of receiving the investigational product will influence your responses or expectations in the study.

Who can participate in this study?

This study is for patients with open-angle glaucoma and ocular hypertension (elevated intraocular pressure).

How long will the study last?

If you meet eligibility requirements during a screening and baseline exam, you will be scheduled for your study procedure.  Following the procedure, you will be required to complete 16 study visits over a 3-year period, which is only a few visits more than standard glaucoma care.  Visits need to be completed within specific intervals.  If you join the clinical study, the Travoprost Intraocular Implant, study drops–including Timolol — as well as all study visits and any specific examinations associated with the study (and eye studied), will be provided to you at no cost.

GLAUKOS iStent infinite® CLINICAL STUDY

(not actual size)

About the study…

A tiny medical device called the iStent infinite Trabecular Micro-Bypass stent is being tested in an investigational study to help alleviate high eye pressure in patients with refractory glaucoma. The iStent infinite stents may help lower the pressure in your eye (intraocular pressure, or IOP). They do this by providing channels for fluid to move out of the front chamber of the eye. Less fluid in the chamber means lower pressure and this may be beneficial in managing your glaucoma.

The iStent infinite procedure consists of placing 3 stents in 3 separate locations in your eye, inserted through a small opening in your cornea. The iStent infinite stents are placed within the natural drainage canal of the eye and are implanted with the goal of lowering pressure. This is done by opening a passage into the existing drainage system that allows fluid to flow out.

How many people will receive the device?

All patients that meet specific study criteria and agree to be part of this study will receive the devices.

Who can participate in this study?

If you have had previous glaucoma surgery and been told by your eye doctor that your eye pressure is not well controlled by medications you are on, you may be able to participate in this clinical study.

How long will the study last?

If you meet eligibility requirements during a screening and baseline exam, you will be scheduled for your study procedure.  Following the procedure, you will be required to complete 6 study visits over a 12-month period.  During these visits, you will also complete a questionnaire and eye examination procedures, so that you and your physician can track your progress.
