Among the 11 patients receiving the device, none suffered retinal detachment, major hemorrhages, inflammation or vitreoretinal tractions -- the major safety concerns for such a procedure.
Session organizer Dr. Daniel F. Martin of the Cleveland Clinic commented afterward that the device was a promising development, calling it "terrific work."
"The patient was able to read his name. That's truly a remarkable thing to do," he said, even if the resulting acuity still falls short of normal.
"All surgery is going to have some risk, obviously, but given the fact that [patients] are destined to complete blindness for the rest of their life without it, it's one that probably most patients will take," Martin added.
The study was funded by Retinal Implant AG. Wrobel is an employee of Retinal Implant. Martin declared he had no relevant financial interests.
