Comparing Effectiveness of the Hydrus Microstent (TM) to Two iStents to Lower IOP in Phakic Eyes

A Prospective, Multicenter, Randomized Comparison of the Hydrus to the iStent® for Lowering Intraocular Pressure in Primary Open Angle Glaucoma

This clinical trial compares two implantable devices intended to lower the pressure inside the eye of glaucoma patients.

This is a prospective, multicenter, single-masked, randomized clinical trial comparing the Hydrus Microstent to two iStent implants for the reduction of intraocular pressure in phakic patients with a positive diagnosis of primary open angle glaucoma, pseudoexfoliative glaucoma, or pigmentary dispersion glaucoma. Post-operative follow-up visits will be conducted at regular intervals.

Inclusion Criteria:

• A diagnosis of primary open angle glaucoma (POAG), Pseudoexfoliative (PXG) glaucoma, or Pigmentary glaucoma (PG)
• A phakic lens with BCVA of 20/30 or better

Exclusion Criteria:

• Forms of primary or secondary glaucoma not listed above
• Prior glaucoma surgery in the study eye
