There’s an impression that traditional glaucoma surgery trabeculectomy is more effective at lowering pressure than canaloplasty. This impression is based on the fact that trabeculectomy can get pressures very low, sometimes even, too low in the eye. But recent studies which have compared canaloplasty directly against trabeculectomy do not show a significant difference in final pressure or in the final number of drops that people used after surgery. So in recent academic studies that even presented in national meetings and published in pure review journals, there’s no evidence that trabeculectomy is actually better than canaloplasty. One thing that is worth noting however, is that study after study, shows that canaloplasty is a safer option than trabeculectomy..
