Minimally Invasive Glaucoma Surgeries
Minimally invasive glaucoma surgery (MIGS) is a type of surgical procedure that has been developed to provide patients with a less invasive and safer alternative to traditional glaucoma surgeries. Unlike traditional surgeries, which involve creating a large incision in the eye, MIGS procedures use small incisions and advanced technology to treat glaucoma while minimizing trauma to the eye. Here are some different types of MIGS procedures:
iStent - The iStent is a tiny, implantable device that is used to lower eye pressure in patients with mild to moderate open-angle glaucoma. It is the smallest medical device ever approved by the FDA and is inserted into the eye during cataract surgery. The iStent creates a new pathway for fluid to leave the eye, reducing intraocular pressure. Read more here.
Hydrus Microstent - The Hydrus Microstent is a device that is designed to reduce intraocular pressure by restoring natural outflow pathways in the eye. It is placed in the eye during cataract surgery and works by expanding the natural drainage channel in the eye.
XEN Stent - The XEN stent is a minimally invasive glaucoma surgery that uses a small, flexible tube made of a gelatinous material to create a new drainage pathway for aqueous humor. The stent is placed in the eye through a small incision made in the cornea and creates a passage for fluid to flow from the anterior chamber to the subconjunctival space. The XEN stent is designed to reduce intraocular pressure by enhancing the outflow of aqueous humor from the eye. Read more here.
Preserflo MicroShunt - The Preserflo MicroShunt is a small, biocompatible tube that is inserted into the eye to create a new drainage pathway for aqueous humor. The MicroShunt is designed to reduce intraocular pressure by allowing fluid to flow from the anterior chamber of the eye to a pocket beneath the conjunctiva, which absorbs the fluid. This procedure is less invasive than traditional glaucoma surgery. Read more here.
Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) - Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) is a minimally invasive glaucoma surgery that involves creating a new drainage pathway for aqueous humor by accessing the trabecular meshwork through an incision in the trabecular meshwork. This procedure is performed using a small endoscope that allows the surgeon to see inside the eye and identify the trabecular meshwork. A microcatheter is then inserted through the incision and used to open the trabecular meshwork, creating a new pathway for aqueous humor to drain. GATT is a relatively new procedure that has shown promising results in reducing intraocular pressure and minimizing the need for medication in patients with glaucoma.
Endocyclophotocoagulation (ECP) - ECP is a laser-based procedure that is used to treat glaucoma by reducing the production of intraocular fluid. It involves using a laser to target the ciliary body, which is responsible for producing fluid in the eye. The laser destroys some of the cells in the ciliary body, reducing fluid production and lowering intraocular pressure.
In summary, MIGS procedures are a valuable option for patients with glaucoma who want to avoid traditional, more invasive surgical procedures. These procedures are less traumatic and can be performed more quickly, with a faster recovery time. However, as with any surgical procedure, it is important to discuss the benefits and risks with your ophthalmologist to determine if MIGS is the best option for you.
