Key: lighter blue is iStent inject + Phaco (N=380) and blue is Phaco along (N=118)

In the US IDE Trial (n=505 subjects), iStent inject® met all study endpoints and demonstrated a clinically significant reduction in IOP for iStent inject® subjects at 24 months.

  • 75.8% of iStent inject® subjects had ≥ 20% reduction in unmedicated DIOP
  • 7.0 mm Hg reduction from baseline in unmedicated DIOP

Other Observed Data:

  • 17.1 mm Hg mean medication-free IOP at 24 months
  • 63.2% medication-free DIOP ≤ 18 mm Hg at 24 months
  • Mean of 0.4 medications at 23 months, down from preoperative mean of 1.6 for the treatment arm

Independent Clinical Study Results

Additional independent, long-term studies of Glaukos trabecular micro-bypass technology suggest that results are maintained several years after the procedure.

Long-Term IOP Reduction5

Chart showing intraocular pressure over time: preop at 22.3 decreasing to 14.8 at year three.

In a consecutive case series with three-year follow-up, mean IOP was 14.3 ± 1.7 mm Hg, representing a 37% reduction from preoperative medicated mean IOP of 22.6 ± 6.2 mm Hg; and 100% of eyes had IOP ≤ 18 mm Hg.

Sustained Medication Reduction5

A bar graph showing sustained medication reduction: mean medication use was decreased from 2.5 to 0.8 medications at three years, a 68% reduction. Reduction key: dark green is 0 Med, green is 1 Med, dark blue is 2 Med, bright blue is 3 Med, blue is 4+ Med.

In the same consecutive case series, mean medication use was decreased from 2.5 to 0.8 medications at three years, a 68% reduction; and 74% of eyes were using 0 or 1 medication compared to 21% preoperatively.

Safety

In the US IDE pivotal study, iStent inject® had no reports of hypotony, significant hyphema, flat anterior chamber, choroidal hemorrhage or effusion, or myopic shift.1,6

Medication reduction is subject to the discretion of the physician.

iDose® TR (travoprost intracameral implant)
Important Safety Information

Dosage And Administration

For ophthalmic intracameral administration. The intracameral administration should be carried out under standard aseptic conditions.

Contraindications

iDose TR is contraindicated in patients with active or suspected ocular or periocular infections, patients with corneal endothelial cell dystrophy (e.g., Fuch’s Dystrophy, corneal guttatae), patients with prior corneal transplantation, or endothelial cell transplants (e.g., Descemet’s Stripping Automated Endothelial Keratoplasty [DSAEK]), patients with hypersensitivity to travoprost or to any other components of the product.

Warnings And Precautions

iDose TR should be used with caution in patients with narrow angles or other angle abnormalities. Monitor patients routinely to confirm the location of the iDose TR at the site of administration. Increased pigmentation of the iris can occur. Iris pigmentation is likely to be permanent.

Adverse Reactions

In controlled studies, the most common ocular adverse reactions reported in 2% to 6% of patients were increases in intraocular pressure, iritis, dry eye, visual field defects, eye pain, ocular hyperaemia, and reduced visual acuity.

Indications And Usage

iDose TR (travoprost intracameral implant) is indicated for the reduction of intraocular pressure (IOP) in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT).

Please see full Prescribing Information.

You are encouraged to report all side effects to the FDA. Visit www.fda.gov/medwatch, or call 1-800-FDA-1088.

iStent infinite® Important Safety Information

Indication for Use

The iStent infinite® Trabecular Micro-Bypass System Model iS3 is an implantable device intended to reduce the intraocular pressure (IOP) of the eye. It is indicated for use in adult patients with primary open-angle glaucoma in whom previous medical and surgical treatment has failed.

Contraindications

The iStent infinite is contraindicated in eyes with angle-closure glaucoma where the angle has not been surgically opened, acute traumatic, malignant, active uveitic, or active neovascular glaucoma, discernible congenital anomalies of the anterior chamber (AC) angle, retrobulbar tumor, thyroid eye disease, or Sturge-Weber Syndrome or any other type of condition that may cause elevated episcleral venous pressure.

Warnings

Gonioscopy should be performed prior to surgery to exclude congenital anomalies of the angle, PAS, rubeosis, or conditions that would prohibit adequate visualization that could lead to improper placement of the stent and pose a hazard.

MRI Information

The iStent infinite is MR-Conditional, i.e., the device is safe for use in a specified MR environment under specified conditions; please see Directions for Use (DFU) label for details.

Precautions

The surgeon should monitor the patient postoperatively for proper maintenance of IOP. Three out of 61 participants (4.9%) in the pivotal clinical trial were phakic. Therefore, there is insufficient evidence to determine whether the clinical performance of the device may be different in those who are phakic versus in those who are pseudophakic.

Adverse Events

The most common postoperative adverse events reported in the iStent infinite pivotal trial included IOP increase ≥ 10 mmHg vs. baseline IOP (8.2%), loss of BSCVA ≥ 2 lines (11.5%), ocular surface disease (11.5%), perioperative inflammation (6.6%) and visual field loss ≥ 2.5 dB (6.6%).

Caution

Federal law restricts this device to sale by, or on the order of, a physician. Please see DFU for a complete list of contraindications, warnings, precautions, and adverse events.
