BayCare’s Green Bay Eye Clinic introduces the ORA system to cataract patients
Monday, January 20, 2014
Cataract surgeons at the Green Bay Eye Clinic have been striving to provide reliable and personalized outcomes for cataract surgery patients in Northeast Wisconsin. Now we are proud to be the first in the Green Bay area to utilize another new revolutionary technology, the ORA (Optiwave Refractive Analysis) system, to further enhance patient's cataract surgery results. My partners and I at the Green Bay Eye Clinic use ORA measurements to guide the procedure, allowing us to provide a tailored treatment of each patient's eye, and helping to ensure our patients get the best possible vision.
How does ORA help?
Once a cataract has been removed, the natural lens of the eye is replaced with an intraocular lens (IOL) in order to restore, and in many cases improve, distance vision. ORA is a diagnostic device, used during cataract surgery after the clouded cataract is removed, to determine the optimal IOL.
Before the ORA system, one had to select the IOL's lens prescription based on measurements taken prior to cataract removal. This sometimes made it difficult to precisely predict what the prescription might be after surgery, and there was always a margin of uncertainty when making the proper selection.
There are certain situations, such as if patients have had previous refractive surgery (LASIK, PRK, etc.), when the measurements taken prior to surgery are not accurate. Therefore the IOL selection based on that measurement make patients' prescription after surgery and visual outcome less predictable.
Using ORA, ophthalmologists at the Green Bay Eye Clinic can now, for the first time, take measurements during surgery to ensure the IOL is more accurately selected, which helps give patients a better visual outcome. Cataract patients will benefit from the increased precision, regardless of which IOL has been selected. This new measurement tool, combined with advanced IOL's, such as Toric or Multifocal IOLs, can further increase the chances of reduced reliance on eyeglasses or contacts after cataract surgery. Our patients can expect more customized, precise vision results than ever before.
