Advantages to the “micro-invasive glaucoma surgery” and the iStent:
Minimal invasiveness and minimally traumatic
It is performed at the time of cataract surgery, requiring no additional incisions other than those needed for cataract surgery itself.
Directly improves the flow of fluid in the eye in the way it was originally intended (i.e. it improves physiologic outflow).
The iStent accomplishes this by “bypassing” the aspect of the drainage system responsible for most glaucoma patient’s high pressures (the trabecular meshwork).
The risks associated with performing cataract surgery with the iStent are essentially equal to those of performing cataract surgery alone.
Traditional glaucoma surgeries (trabeculectomy and tube shunts) carry a far higher risk
Rapid recovery time
Patient’s recovery time is quite rapid which allows a return to normal activities much more rapidly than with other forms of glaucoma surgery.
Most patient’s experience a reduction in intraocular pressure and/or a reduction in the medications they are taking for glaucoma*
*Due to the progressive nature of glaucoma, patient’s who undergo the implantation of an iStent still may require additional medications and or surgical interventions to control intraocular pressures in the future (despite the proven safety/efficacy of the iStent).
