FAQs / Can Canaloplasty NOT Be Done after a Trab W/ EX-Press or Trab Alone?


Dear ******,

This is not a question that can be answered with a simple “yes” or “no”. It depends upon whether the canal was cut through during creation of the trabeculectomy site. In general it is much easier to perform Canaloplasty after an Ex-PRESS mini shunt is used as the shunt is inserted anterior (in front of) the canal. So long as the canal is intact it should be possible to fully catheterize and stent it open during Canaloplasty. That being said, it is still possible (though exceedingly challenging) to perform Canaloplasty after a trabeculectomy that has cut out a portion of the canal. More information can be found here:
