DESCRIPTION AND INTENDED USE
The Kahook Dual Blade
used in ophthalmic surgical procedures to manually cut trabecular meshwork (TM) in
pediatric and adult patients. The KDB is sterile and is intended for single patient, single use.
The KDB consists of a surgical grade stainless steel body and a plastic handle. The stainless
steel body is comprised of a long thin neck that allows for access to the TM, a pointed tip
used to pierce TM, a ramp that lifts and stretches tissue as the device is advanced, and
two thin blades that cut TM. An indicator on the plastic handle specifies the direction to
advance the KDB.
CONTRAINDICATIONS
Like most angle surgeries, proper visualization using a gonioprism is key to manually cutting
TM with the KDB. Do not attempt to use the KDB if corneal clarity is poor or if visualization
of angle structures is not possible.
CAUTION: Do not use the KDB if you are not trained for intraoperative gonioscopy or have
poor visualization of angle structures. Improper visualization may result in misuse of the KDB
and damage to eye structures adjacent to the TM.
