Short answer
ORA (Optiwave Refractive Analysis) measures refraction during cataract surgery — after trial lens insertion, before final IOL power commitment. Most valuable in post-LASIK cataract eyes where formulas are less predictable.
What is this system?
Intraoperative aberrometry attached to the microscope — aphakic or pseudophakic measurement guides IOL power refinement.
Where it fits in cataract or RLE surgery
Decision support mid-surgery — surgeon interprets ORA data with clinical judgement.
Clinical benefits vs manual steps
- ✓Post-refractive cataract eyes — reduces IOL power surprise.
- •Toric refinement — confirms axis in selected cases.
- •Real-time feedback — adjust lens choice before patient leaves OR.
How it pairs with premium IOLs
Complements IOLMaster pre-op biometry and VERION marking.
