Kahook Dual Blade Ab-interno Trabeculotomy Versus ab Externo Viscotrabeculotomy in Primary Congenital Glaucoma

Introduction:

Ab externo viscotrabeculotomy is known as an effective surgical procedure used for managing primary congenital glaucoma (PCG) in which the Schlemm's canal (SC) is identified and a metal probe is inserted into the canal and rotated into the anterior chamber (AC) to perforate the SC inner wall.

Recently, Kahook dual blade (KDB) have been developed as one of the micro-invasive glaucoma surgical tools which removes a strip of the trabecular meshwork(TM) at the angle with superiority to simple goniotomy in treating the angle pathology in PCG.

The Kahook dual blade® (KDB) assisted ab-interno trabeculotomy is a simple procedure usually performed at the time of cataract surgery. It doesn't require sutures, and it carries no risk of bleb leaks or infections. It has a a quicker postoperative visual recovery than most other glaucoma treatments. The KDB device is specifically designed to produce targeted and fine tuned parallel incisions in the trabecular meshwork tissue for a quick and effective glaucoma treatment. The KDB's unique design enables precise excision of diseased trabecular meshwork (TM) to access multiple collector channels.

The KDB's unique design enables the operator to perform excisional goniotomy both during cataract surgery and as a stand alone procedure. The Kahook Dual Blade is a precise, intuitive surgical instrument utilized to perform excisional goniotomy.
