Modern micro-invasive procedures including Kahook Dual Blade goniotomy and Gonioscopy-Assisted Transluminal Trabeculotomy.
Minimally Invasive Glaucoma Surgery (MIGS) represents the latest frontier in glaucoma therapeutics, bridging the gap between medical drops/lasers and invasive traditional filtration surgery. MIGS procedures utilize microscopic incisions, ab-interno gonioscopic guidance, and tissue-sparing techniques to enhance natural outflow with exceptionally high safety profiles.
At Atharva Glaucoma Centre, Dr. Amola Gandhi offers leading-edge MIGS interventions including Kahook Dual Blade (KDB) excisional goniotomy and Gonioscopy-Assisted Transluminal Trabeculotomy (GATT). These innovative procedures can be performed stand-alone or seamlessly combined with routine cataract surgery (phacoemulsification), allowing patients to achieve lower pressures and reduce their drop burden.
Kahook Dual Blade (KDB) Excisional Goniotomy utilizes a precision-engineered micro-surgical blade with dual parallel cutting edges. Guided by high-magnification intraoperative gonioscopy, the blade enters through a clear corneal micro-incision (1.8 to 2.2 mm) and strips away a strip of diseased trabecular meshwork without collateral damage to adjacent sclera or collector channels.
Gonioscopy-Assisted Transluminal Trabeculotomy (GATT) is an ab-interno 360-degree trabeculotomy. A micro-illuminated optical catheter is threaded smoothly through the entire 360-degree circumference of Schlemm's canal, then pulled through to cleave the entire resistant meshwork, restoring full circumferential natural drainage.
Because MIGS procedures operate entirely inside the anterior chamber without creating an external subconjunctival filtration bleb, the conjunctiva remains undisturbed and healthy.
Patients enjoy rapid visual recovery within 24 to 48 hours, minimal post-operative discomfort, and virtually zero risk of bleb infections or hypotony.
Why MIGS is transforming glaucoma management worldwide:
Yes! Combining KDB or GATT with routine cataract surgery is one of the most effective strategies available today, allowing patients to treat both cataracts and glaucoma in a single comfortable 20-minute procedure.
MIGS is ideal for mild-to-moderate open-angle glaucoma, ocular hypertension, patients struggling with eye drop side effects, or those needing combined cataract surgery. Dr. Gandhi will evaluate your angle to confirm candidacy.
No. MIGS utilizes self-sealing corneal micro-incisions that do not require sutures, eye patches, or hospital stays.
