Purpose: The aim of this trial was to evaluate the safety and efficacy of a trabecular micro-bypass stent iStent combined with phacoemulsification in subjects with mild to moderate primary open angle glaucoma.

Methods: A prospective, randomized, open, controlled, clinical trial was performed an Mexico’s Central Militar Hospital. The intervention was the implantation of a trabecular micro-bypass stent (iStent) combined with cataract surgery. 23 patients whom met the inclusion criteria were recruited into the trial. Intraocular pressure, best corrected visual acuity, visual field functional study, and the use of hypotensive drugs was documented and the patients were divided into two random groups, one underwent cataract surgery and the other underwent cataract surgery plus a trabecular microbypass stent (iStent) implantation.

Results: There was a reduction of up to 75% in the use of topical hypotensive drugs after one year iStent implantation.

Conclusion: The use of the iStent combined with phacoemulsification results in a sustained hypotensive effect in Mexican patients diagnosed with primary open angle glaucoma.
