CHICAGO — A suprachoroidal stent may offer relief for patients undergoing cataract surgery who have concurrent high IOP, a presentation here suggested.

“The CyPass Micro-Stent seems to be a nice option for a minimally invasive procedure that is done ab interno. It has excellent safety, and so far the results, as far as what we are seeing with IOP reduction, are favorable,” E. Randy Craven, MD, said at the American Society of Cataract and Refractive Surgery meeting.
The CyPass Micro-Stent (Transcend Medical) consists of a biocompatible, non-degradable polyimide material that is implanted through a 1.5-mm clear corneal incision, acting as a conduit in the supraciliary space. According to Dr. Craven, the device offers three core advantages: It enables controlled cyclodialysis, it increases non-trabecular outflow, and it is minimally invasive.
There were 184 eyes included in the prospective, multicenter, interventional case series conducted by Dr. Craven and colleagues; 93 presented with IOP less than 21 mm Hg, and 91 had a higher pressure.
Of those with higher baseline IOP, 66 patients who presented for 3-month follow-up demonstrated a mean IOP reduction of roughly 40%. The 31 patients who presented for 12-month follow-up showed a roughly 34% decrease.
At last follow-up, no major adverse events had been reported; however, a transient IOP increase of less than 10 mm Hg was observed in 10.5% of patients.
