ORA Refractive AnalysisORA (Optiwave Refractive Analysis) system technology is a sophisticated device that provides real time measurements of the patient’s eye during cataract surgery. This allows for the surgeon to take measurements of the patient’s eye in the operating room to optimize decision making for correcting the vision. We use this technology to fine tune lens choices, measure residual astigmatism that may need to be fixed and verify the proper position of a toric lens implant. The ORA technology becomes very important in situations where the measurements taken in our office may not be perfectly reliable. One example is for patient’s that have undergone previous refractive surgery (LASIK, PRK, etc.)
