Abstract Details


This presentation describes a stepwise approach to performing the OMNI surgical procedure combined with cataract surgery. The OMNI procedure uses a single self-sealing corneal incision for an ab-interno 360 degrees viscodilation of Schlemm’s canal followed by 360 degrees transluminar trabeculotomy to treat glaucoma.


University and Polytechnic Hospital La Fe, Valencia, Spain


Surgical steps using the OMNI surgical procedure combined with cataract surgery will be described in a 70-year old male with uncontrolled primary open-angle glaucoma (POAG) on maximum therapy.


This presentation contains 8 practical/graphic steps: (1) Materials and OMNI device priming, (2) Clear corneal incision, anterior chamber preparation for a good angle structure visualization, (3) Introduction of the microcatheter into Schlemm’s canal, (4) Viscodilation of Schlemm’s canal and collector channels in the superior 180º, (5) Viscodilation in the inferior 180º, (6) Trabeculotomy in the inferior 180º, (7) Trabeculotomy in the superior 180º, (8) Cataract surgery. OMNI surgery combined with Cataract surgery uses only 2 self-sealing clear cornea incisions.


In treating adult glaucoma, the OMNI surgical system allows combining two minimally invasive surgical procedures via a single clear corneal incision that, 1) viscodilates Schlemm's canal and collector channels along with, 2) the opening of trabecular meshwork. If performed sequentially with cataract surgery, then it is important to perform cataract surgery after the OMNI procedure. Otherwise, a capsular decompression from the cataract surgery could trigger the presence of blood in Schlemm’s canal, which can make angle surgeries such as OMNI more challenging due to increased bleeding.
