Who Will Likely Benefit from the Stegmann Canal Expander®?

Who Will Likely Benefit from the Stegmann Canal Expander®?

Most anyone who is a candidate for canaloplasty should also benefit from placement of the Stegmann Canal Expander®. At the time of this writing, however, only those outside of the USA can do so as the FDA has yet to approve this device.

Stegmann Canal Expander® – Summary

Canaloplasty already offers an impressive IOP lowering benefit with minimal risk to the patient with glaucoma. However, it is a technically challenging and time-consuming surgery to perform. The addition of the Stegmann Canal Expander® may provide even greater IOP lowering benefit. I am looking forward to future studies comparing canaloplasty with the Stegmann Canal Expander® to trabeculectomy. If, as I expect to be the case, there is no significant IOP lowering benefit with trabeculectomy but much greater risk with trabeculectomy, then it is my hope that more US-based surgeons will make the effort to learn this technique for the benefit of their patients.
