INDICATION: The EX-PRESS® Glaucoma Filtration Device is intended to reduce intraocular pressure in glaucoma patients where medical and conventional surgical treatments have failed.
GUIDANCE REGARDING THE SELECTION OF THE APPROPRIATE VERSION: Prior clinical studies were not designed to compare between the various versions of the EX-PRESS® Glaucoma Filtration Device. The selection of the appropriate version is according to the doctor's discretion.
CONTRAINDICATIONS: The use of this device is contraindicated if one or more of the following conditions exist:· Presence of ocular disease such as uveitis, ocular infection, severe dry eye, severe blepharitis.· Pre-existing ocular or systemic pathology that, in the opinion of the surgeon, is likely to cause postoperative complications following implantation of the device.· Patients diagnosed with angle closure glaucoma.

~ 2002
• Participated in certification course
• Never did a case...
• “The EX-PRESS® Device is Glaucoma Roulette”
~2007-2009
• Willing to take another look
2009 - 2011
• “Love the EX-PRESS® Device!”

EX-PRESS® Glaucoma Filtration Device Procedure
Minimally invasive
Little if any shallowing of AC
No need to release traction suture
Less “open eye” risk: less SCH vulnerable

EX-PRESS® Device Guarded Filtration Procedure
Minimally invasive...
No risk of iris prolapse
No risk of bleeding from ciliary body
More wound control
Less Induced Astigmatism
More posterior flow

The same sclerostomy every time...

EX-PRESS® Guarded Filtration Procedure
Standardized sclerostomy
Not Standardized trabeculectomy!
But...Safer, More elegant,More reproducible,Less invasive

EX-PRESS® device does not have to get better results to be safer/more controlled and more elegant.
A better experience for surgeon and, more importantly, for the patient

Why Not Tubes?
I love tubes...
But not as my first surgery in most patients

Incremental Improvements
The EX-PRESS® device is not the final answer in our quest for a standardized glaucoma operation
It is a good next step
Surgeons will make it better
There is a learning curve for post op care

We must reduce the stagnation in
glaucoma surgery innovation!

What about the cost?
•Dear Patient ...
•“I am sorry. Society can’t afford to improve on the glaucoma surgery of 1980’s”
•(antimetabolite filtering era)
EXP11748SK
We spend a fortune meticulously documenting disease progression
Visual fields, disc imaging, NFL imaging, angle imaging
EXP11748SK
Our advances in imaging and in pharma are fabulous. But where is the investment in
our surgical treatment options?
Enough already, We need to move our surgical procedure forward!
EXP11748SK
We have not invested in the surgical treatment of Glaucoma This is our time!
For the first time we have industry R & D resources focused on glaucoma. Some very smart people looking to help us!• If we ignore them, if we are satisfied with 1980s surgical methods, they will go elsewhere with their resources!
