FAQs / Is It True That Both Trab W/ EX-Press and Trab Alone Have More Potential to Achieve a Lower Pressure than a Canaloplasty?


Dear ******,

In general that is true if Mitomycin-C (MMC) is used. However, that extra IOP lowering comes at a cost and I’m not talking about dollars. The price is paid in risk: risk of loss of vision, hypotony with associated maculopathy, lifetime (of the bleb) risk of infection, increased ocular surface disease (dry eye irritation), etc. There is at least one study, however, that showed no difference between the average IOP reduction from Trab+MMC and Canaloplasty. This study was performed by one of the most skilled eye surgeons I know, Ike Ahmed (in Canada):

In addition, it’s simply not true that you cannot achieve an IOP below 10mmHg off drops after Canaloplasty. I have a number of patients who are now years out from Canaloplasty who have IOPs in the
