Advanced Technology in Cataract Surgery

ORA

Optiwave Refractive Analyzer (ORA) gives surgeons the ability to measure, adjust, and affirm intraocular lens (IOL) power and alignment.

These on-demand measurements of the most critical aspects of the surgery have the potential to enhance visual outcomes.

This technology is often helpful in every patient, but can be especially useful in patients who have previously been more challenging when calculating the power of the IOL that is implanted at the time of cataract surgery.  This may occur in patients who have had previous refractive surgery such as LASIK, PRK, or RK, extreme near or far-sightedness, or higher amounts of astigmatism.

How does ORA work?

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 astigmatism.

When ORA is used, it performs 40 instantaneous calculations to measure the refractive power of the eye. This allows us to confirm or refine your IOL selection with real-time data.
