Alcon’s ORA System Reaches 2 Million Cases

Alcon announced its Optiwave Refractive Analysis (ORA) intraoperative aberrometer system has reached 2 million cases worldwide. This milestone signifies an important leap forward in cataract surgery by delivering greater accuracy than preoperative calculation methods alone.  

The ORA System measures the total ocular refraction to avoid refractive surprises and power real-time, in-procedure adjustments. With each procedure, it captures the new data in its AnalyzOR database—now putting over 2 million cases of data at the surgeon’s fingertips. This repository is re-optimized quarterly to ensure refractive outcomes with the ORA System continue to improve over time. Real-time intraoperative refraction complements theoretical pre-op eye model data and global trend data to verify IOL power against pre-op calculations.

Unlike traditional methods of calculating IOL power, the ORA System captures a total ocular refraction measurement that accounts for total ocular astigmatism, including surgically-induced astigmatism and posterior corneal astigmatism, as well as post-myopic PRK/LASIK and long and short eye measurements to provide guidance for adjustments of lens selection and placement for all eye types, according to Alcon. The ORA AnalyzOR database can identify outliers mid-procedure to help surgeons hit refractive targets with more precision and consistency. Postoperatively, it verifies IOL power constants against manufacturer recommendations with global outcomes data to calculate optimized global and surgeon-specific lens constants.  

A recent white paper, “Cataract Surgery: Optiwave Refractive Analysis in Post-Refractive Patients,” authored by Drs. Helga P. Sandoval and Raiju Babu, showed that ORA can substantially increase the accuracy of lens power selection during cataract surgery and decrease the prediction error compared with preoperative formulas in patients with prior myopic LASIK.¹Another study, “Astigmatic Results of a Diffractive Trifocal Toric IOL Following Intraoperative Aberrometry Guidance,” authored by Drs. John F Blaylock and Brad Hall, showed that intraoperative aberrometry demonstrated improved accuracy of astigmatic lens selection in cases of trifocal toric implantation with post-op patients.²

Alcon’s cloud-based integration between the ORA, AnalyzOR and the ARGOS Biometer is powered by Philips Health Suite to provide a streamlined approach to practice data management with automatic data sharing from the clinic into the operating room, all backed by Windows 10 software and security upgrades.
