Dr. Swann has the ability to measure outcomes, correct astigmatism and verify lens implant calculations in real time during cataract surgery with the introduction of Optiwave Refractive Analysis (ORA). During cataract surgery, Dr. Swann removes the cloudy, natural lens and replaces it with an intraocular lens implant (IOL).
The ORA is attached to the surgical microscope and utilizes intraoperative wavefront aberrometry to measure the refractive power of the eye once the cataract is removed. This on-demand power calculation is then used to ensure proper implant power, IOL placement, and/or determination of the magnitude and direction of the astigmatism.
