what is the kahook dual blade?

The Kahook Dual Blade (KDB) goniotomy is a newly developed MIGS (minimally invasive glaucoma surgery) procedure that we are pleased to offer at Focal Point Vision in San Antonio, TX. Utilizing the KDB, our board-certified ophthalmologists, Drs. Kenneth Maverick and James Lehmann, make an opening in the natural drainage pathway of the eye with one small incision. The KDB goniotomy has provided exceptional results for men and women and is known to improve the flow of intraocular fluid, lowering the internal eye pressure that causes glaucoma and reducing the risks of damaging the optic nerve. Eligible candidates for this treatment are typically those with mild to moderate open- or closed-angle glaucoma.

What are the benefits?

At Focal Point Vision, our Kahook Dual Blade system has many benefits for treating our glaucoma patients, including:

  • Pain-free procedure that will not interfere with the rest of your day
  • Quick, in-office procedure that lasts no more than 30 minutes if performed on its own
  • High levels of provider and patient satisfaction
  • More complete removal of lesions interfering with intraocular fluid than other competitors


The KDB goniotomy is done as an outpatient procedure at our San Antonio, TX office. Before we begin, we will administer IV sedation to keep you calm and comfortable during the treatment. We will also utilize numbing eye drops to fully desensitize the area. Once you are relaxed and ready, one of our eye surgeons will create a tiny incision into the cornea. The area within is then inflated slightly with a special medical-grade fluid to create optimal visual success. The Kahook Dual Blade is then inserted, which provides two functions: to remove a tiny section of the trabecular meshwork and enlarge the drainage area.

Kahook Dual Blade FAQ

Does the Kahook Dual Blade treatment hurt?

Before your KDB procedure begins, Dr. Maverick or Dr. Lehmann will administer IV sedation to make you comfortable; and anesthetic drops to numb the eye. Most patients don’t experience any pain or discomfort during the procedure.

How long does a Kahook Dual Blade goniotomy take?

The KDB procedure is relatively quick and only takes about 10 - 20 minutes. If it is performed along with cataract surgery, it will take longer.

Is the KDB (Kahook Dual Blade) safe?

Studies have shown that the KDB goniotomy procedure is both safe and effective for reducing intraocular pressure (IOP) and the need for medications to treat severe glaucoma. The safety profile has been described as outstanding and consistent with other glaucoma treatments.

How long is recovery after a Kahook Dual Blade goniotomy?

You will be able to go home the same day as your procedure, although someone will have to drive you. We will prescribe antibiotic and steroid eye drops that you’ll need to take for a few weeks. You will need to come back at least twice so we can monitor the recovery process.
