ORA-Guided Cataract Surgery

This revolutionary system is the first of its kind to gather data from no-contact intraoperative wavefront aberrometry during cataract surgery, rather than having to 'wait and see' as with traditional cataract surgery. Using this information, the ORA System helps us select intraocular lenses, or IOLs, that match a patient’s precise needs regarding lens power, magnitude and axis of astigmatism, and aphakic and pseudophakic measurements.

ORA System’s optimizations are a result of nearly 80,000 cataract procedures performed using WaveTec technology.  Whether the patient has had LASIK or has astigmatism, an ORA-guided cataract procedure provides the security of knowing they can have the best possible outcome, and reduce the chance of needing an additional procedure.

This new technology is proven to significantly improve post-op outcomes compared to in-office biometry and intraocular lens formulas: Nearly 80 percent of ORA-guided patients are within 0.50 diopter of intended visual outcome post-op, compared to 60 percent with traditional cataract surgery. ORA is also proven to be particularly effective at reducing -- by as much as two to five times -- the need for a follow-up or enhancement procedure.

Benefits of the ORA System

There are many benefits associated with use of the ORA System:

  • Prediction Error Gap: Clinical data reveals there is an 8 percent prediction error and distribution gap at .50 diopters between the outcomes achieved by cataract refractive surgeons using the ORA System, versus traditional biometry.
  • Toric Cylinder Reduction Success: The ORA System provides significantly better cylinder reduction with Toric intraocular lenses than previous technologies.
  • The ORA/Femto Advantage: The synergy between the ORA System and laser-assisted refractive cataract surgery has been demonstrated to provide the greatest possible visual outcome for cataract patients.
