WaveTec Vision™, the leader in wavefront-guided Custom Cataract™ technology, announced today that it has closed its Series D financing, securing $15.9 million from existing and new investors. The ORange® intraoperative wavefront aberrometer is a patented diagnostic breakthrough that allows cataract surgeons – for the first time – to measure refraction during surgery, so they can precisely predict and customize how their patients will see following the procedure. ORange Custom Cataract surgery provides on-demand measurements so cataract surgeons can make adjustments on the table, to help ensure their patients achieve the refractive outcome they expect.
