AIM：To describe a novel technique of creating a landing strip within the trabecular meshwork to guide trabecular micro-bypass stent（iStent） implantation in patients who underwent phacoemulsification.METHODS：Thirty-four eyes from 30 patients who underwent i Stent implantation after phacoemulsification from May 2014 to February 2015 were included in our retrospective study. All iStents were implanted via the ＂landing strip＂ technique. A 25-gauge microvitreoretinal blade was used to bisect the trabecular meshwork to less than 1 clock-hour, effectively creating a landing strip. The iStent applicator was pressed along the landing strip and then the stent was released into the trabecular meshwork. RESULTS：Of the 34 eyes with iStent implantation, 27（79.4%） eyes had primary open-angle glaucoma, 6（17.6%） eyes had pseudoexfoliation glaucoma, and 1（2.9%） eye had ocular hypertension. At 6-month follow-up（n=17）, the mean number of hypotensive medications decreased from 2.2±1.2 at baseline to 0.8±1.3（P=0.05） and mean intraocular pressure decreased from 19.7±4.1 mm Hg at baseline to 16.7±2.1 mm Hg（P=0.58）. Two eyes（5.9%） required subsequent trabeculectomy. CONCLUSION：The ＂landing strip＂ technique appears to be an effective way to assist with iS tent implantation.
