ISTENT INJECT W AND KAHOOK DUAL BLADE FOR TREATING MILD-TO-MODERATE GLAUCOMA

This is a review article to contrast the lowering effect of intraocular pressure of two minimally invasive glaucoma surgery (MIGS) devices namely iStent inject (the second edition) versus excisional goniotomy using Kahook dual blade (KDB) as a combo procedure with cataract surgery, as well as post-operative best corrected visual acuity BCVA loss for those with mild to moderate primary open-angle glaucoma. Design: a review article comparing two MIGS devices. Randomization of patients into two categories, one-hundred procedures for iStent injection and the other one hundred for Kahook Dual Blade (KDB). Intraocular pressure (IOP), BCVA, and adverse events were recorded. The fundamental results were the IOP, the post-operative visual acuity and refractive errors. One-hundred operations for each procedure were evaluated and the BCVA loss by two rows or more one year post-operatively. Each procedure seems to have the same safety profile and the same effect on visual acuity (P=0.11). Each device reduces the IOP as well as lowers the reliance on topical hypotensive medications and safety profile for visual acuity post-operatively. The limitation of this review is a relatively small sample size. Additionally, the one-year follow-up time does not present a clue on long-term results in such chronic ocular illness.
