OPHTHALMOLOGY

Alcon announced June 16 that its Optiwave Refractive Analysis (ORA) System had reached 2 million cases worldwide.

The system is composed of an intraoperative wavefront aberrometer and cloud-based AnalyzOR Technology database.

The aberrometer obtains real-time ocular measurements after the removal of the natural lens during cataract surgery to derive sphere, cylinder, and axis measurements.

ORA combines these measurements with calculations made preoperatively and recommends the IOL sphere and cylinder power to be implanted in the eye to achieve the lowest residual refractive error.

Surgeons’ postoperative refractive outcomes are used to further optimize the database.
