✦ ORA™ System with VerifEye+
🎯 Premium IOL Optimization
ORA™ Technology for
Cataract Surgery in Fayetteville, NC
The ORA system measures your eye in real time during surgery — allowing your surgeon to confirm and optimize your IOL selection while you’re on the operating table, for more accurate outcomes than pre-op measurements alone.
What Is the ORA System?
The ORA™ System with VerifEye+ (by Alcon) is an intraoperative aberrometry system — an advanced measurement device that works in real time during cataract surgery to guide intraocular lens (IOL) selection and positioning.
Here’s what makes ORA different from standard pre-surgical measurements: by the time a patient is in the operating room, the eye is already being held open, the cornea is under the microscope, and the cataract has just been removed. At this precise moment, ORA takes live measurements of the eye’s optical power — giving the surgeon real-time data about the actual eye, not just pre-op estimates.
📡 Intraoperative Guidance: Why It Matters
Pre-operative measurements are very good, but they can’t perfectly account for every individual variation — corneal edema, prior laser vision correction, unusual axial length, or complex anatomy. ORA fills that gap by providing one final, real-time measurement at the moment of surgery — confirming the right IOL power is being implanted before the eye is closed.
How Does ORA Work During Surgery?
ORA integrates directly with the surgical microscope. Here’s the step-by-step intraoperative workflow:
1. Aphakic Measurement
After the cataract is removed (but before the IOL is implanted), ORA measures the eye in its “aphakic” state — without any lens. This provides the most accurate refractive baseline possible.
2. IOL Power Confirmation
ORA’s algorithms calculate the optimal IOL power based on the live measurement, comparing it against the pre-operative plan. If conditions warrant, the surgeon can adjust the IOL selection in real time.
3. Toric Axis Alignment
For toric IOLs (astigmatism-correcting lenses), ORA provides real-time visual guidance for optimal lens axis alignment — the most critical factor in toric IOL outcomes.
4. Post-IOL Verification
After the IOL is placed, ORA can verify the refractive outcome — confirming the eye is on target before the surgery is complete. Adjustments can be made while the patient is still on the table.
Who Benefits Most from ORA Technology?
While ORA improves accuracy for all cataract patients, certain situations benefit most from real-time intraoperative guidance:
ORA + LenSx®: The Gold Standard for Cataract Surgery
Carolina Vision Center offers both ORA intraoperative guidance and LenSx® laser-assisted cataract surgery — combining the two most advanced technologies available for cataract outcomes:
LenSx® Laser Precision
Computer-guided femtosecond laser performs the incisions, capsulotomy, and lens fragmentation with sub-micron accuracy — creating the ideal environment for IOL placement.
ORA Real-Time Verification
After LenSx® creates the perfect incisions, ORA confirms the optimal IOL power and toric alignment in real time — a final quality check that maximizes outcomes.
Together, LenSx® and ORA represent the highest standard of care available in cataract surgery — and both technologies are available at Carolina Vision Center in Fayetteville. Learn more about LenSx® →

ORA Technology FAQs
What is ORA used for in cataract surgery?
ORA (Optiwave Refractive Analysis) is an intraoperative aberrometry system that measures the eye in real time during cataract surgery. It confirms the optimal IOL power after the cataract is removed and guides toric IOL axis alignment — improving the accuracy of the final refractive outcome beyond what pre-operative measurements alone can provide.
Does ORA replace pre-operative measurements?
No — ORA complements pre-operative measurements. Your surgeon uses detailed biometry, topography, and IOL formulas before surgery to select the target lens. ORA provides a final real-time verification during surgery, allowing the surgeon to confirm or fine-tune the plan with live data.
Is ORA covered by Medicare?
ORA intraoperative aberrometry is typically an additional out-of-pocket service, similar to premium IOL technology fees. It is most valuable — and most recommended — for patients choosing premium IOLs (multifocal, EDOF, toric) or those with prior laser vision correction. Our team will explain all associated costs during your consultation.
Does ORA add time to the surgery?
The ORA measurement process adds only a few minutes to the surgical procedure. The system integrates directly with the surgical microscope and provides immediate readings — minimal added time for meaningful improvement in precision.
I previously had LASIK — why is ORA especially important for me?
Prior LASIK or PRK changes the corneal curvature, which reduces the accuracy of standard IOL power formulas. ORA measures the eye’s actual refractive state during surgery — after the cataract is removed — giving a more accurate reading than any pre-operative formula can provide for post-LASIK eyes. This significantly improves the probability of achieving your target vision after cataract surgery.
Can ORA help patients avoid needing glasses after cataract surgery?
ORA improves the accuracy of IOL power selection and toric lens alignment — both of which directly impact whether patients achieve their target vision (distance, near, or both) after surgery. When combined with a premium multifocal or EDOF IOL, ORA-guided surgery maximizes the likelihood of achieving glasses independence.
