HOLOS IntraOp device shows qualitative and quantitative refractive data in real time, offering immediate feedback on how surgical adjustments may affect post surgical refraction during the many steps of cataract surgery.

California’s Sacramento Eye SurgiCenter medical director Dr Keith Liang said: "HOLOS IntraOp offers continuous, real-time refractions during cataract surgery, meaning the ability to confirm the refractive target and guide astigmatic treatments.

"Achieving the refractive outcomes patients expect in modern cataract surgery requires a great deal of precision."

The device provides active monitoring of sphere, cylinder, and axis measurements, as well as live feedback to the surgeon while rotating toric IOLs, titrating limbal relaxing incisions and opening arcuate incisions.

It can be used in any cataract surgery, and holds capacity to take 90 measurements per second, with a displayed range of -20.00D to +20.00D and a dynamic range from -5.00D to +16.00D.

The firm is exhibiting HOLOS IntraOp at the American Academy of Ophthalmology (AAO) annual meeting, which is being held from 14 to 17 November.

Clarity Medical, which has several patents in real-time intraoperative wavefront aberrometry, is also planning upgrades to the HOLOS IntraOp platform.

The firm’s current software capabilities provide ability to manage a full range of cataract cases, comprising pseudophakic IOL power confirmation for standard, multifocal, and toric IOLs.

In 2016, the company intends to introduce new software to accurately predict the required IOL power using an aphakic measurement.
