NEW ORLEANS — Clarity Medical Systems is launching the HOLOS Barrett IOL Formula here at the American Society of Cataract and Refractive Surgery meeting, the company announced in a press release.
The formula is an update to the HOLOS IntraOp Wavefront Aberrometer, which supplies real-time, dynamic aphakic measurements during cataract surgery, Barry J. Linder, MD, Clarity’s chief medical officer, said in the release.
The HOLOS Barrett IOL formula, designed by Graham Barrett, MD, Douglas D. Koch, MD, and Warren Hill, MD, is based on the Barrett Universal II and Barrett Rx formulas. It incorporates elements from existing IOL power calculation formulas and adds aphakic intraoperative data, the release said.
The Barrett Universal II formula provides a recommended IOL power for desired spherical equivalent refraction using preoperative biometry measurements.
The Barrett Rx formula incorporates data from the Barrett II, calculated effective lens position and refractive outcome to provide IOL power for postoperative corrections and to minimize postoperative astigmatism.
