The Ex-PRESS Glaucoma Mini-Shunt
Sunday, June 27th, 2010
Recently, I have added using Alcon’s Ex-PRESS Mini-Glaucoma Shunt to the list of surgical options available for our difficult glaucoma patients. The Mini-Shunt is a 400-um wide by 3-mm long stainless steel medical device (about the size of a grain of rice) that offers a minimally invasive approach to dealing with glaucoma cases that cannot be adequately controlled on maximal medical therapy and/or SLT laser treatment.
The shunt works by creating a pathway for intraocular fluid to flow from inside to outside of the eye bypassing the blocked or poorly functioning drain (trabecular meshwork). It provides excellent control of the amount of fluid draining out of the eye by standardizing the drainage opening. In controlled studies, the Ex-PRESS Mini-Shunt had a 94% success rate with a low complication rate compared to traditional glaucoma surgery (trabeculectomy).
The Mini-Shunt is attractive to both patients and surgeons because:
1. It is minimally invasive – No tissue is removed as in traditional glaucoma surgery.
2. Because of this minimally invasive approach, any post-operative inflamatory response is blunted.
3. Post-operatively, eyes are quieter, less red, more comfortable and have better vision sooner.
4. The results appear to be more predictable and complications related to over-filtration in the early post-operative period are lessened.
My experience with the Ex-Press Mini-Shunt has been nothing but positive. And, that same experience holds true from the patient’s point of view. I believe this device is a giant step forward in the surgical treatment of glaucoma.
