So you’re tired of using that old traditional phoropter, and you want something to impress patients- maybe even make your practice look cooler. Any digital refractor will certainly do that, but will it make you more efficient– after all, anything digital in the Ophthalmic world is touted as an efficient alternative to the way things were. Our favorite answer (to most questions) applies here as well- it depends. When the horse and buggy was replaced by motor cars the world quickly understood its more-efficient substitution and the demand was seemingly limitless. The digital refractor however, despite some whom claim it has replaced the horse-and-buggy equivalent “phoropter,” has not seen such a meteoric rise in replacing the older and completely manual instrument. We do see more and more practices making the switch, however it has not taken the universal exam room position like some may have predicted. We did our best to examine why exactly this is and our best guess stems from the following two reasons: 1). Digital Refractors are expensive (at least the new ones are) 2). They’re only marginally more efficient. The Huvitz CDR-3100 is however not so expensive, and when compared to the competition of the manual phoropter, it would seem like a worthy investment. Will it help you see more patients? It once again depends. We do believe all digital refractors marginally shorten the refractive process, however the operator is still required to press/switch/toggle buttons. A custom set program definitely shortens the time it takes to flip through the charts, and since no operator is a computer we do believe this cuts valuable time that would otherwise be spent flipping through all thing necessary for a subjective refraction. We can confidently say a digital refractor is much easier to use in terms of ergonomics; with the help of a set program and a comfy chair, all things can be done by merely pressing a buttons (or two) at your optimal position. It may also help your patients feel more comfortable seeming that your fingers aren’t mere inches from their face. 


OUR TAKE: A great entry-level digital refractor for those seeking to make the manual switch.

92015:  $8.01

Determination of Refractive State

*coverage of the above procedure may be subject to local reimbursement amounts, special provisions, and your own service rate.

*based on CPT 92015 assuming determination of refractive state

Automated JCC system allows patients to compare 1 or 1 without any manual lens flipping.

The phoropter head will automatically measure for the correct vertex distance, and send the results to the console

Corneal illumination comes standard for better alignment.

Digital control pupillary distance all from the touch a button. The CDR’s wide range adjusts for any patient.

Unlike manual phoropters, digital refractors eliminate most variables and ensure perfect convergence.

The console’s adjustable LCD screen can be tilt for viewing at practically any angle– sitting or standing.

The CDR’s software allows data presets to eliminate the need for further lens adjustment– begin every refraction exactly at your determined starting points.

Create up to 10 predefined programs allowing your refractions to stay on schedule every time– just hit “Next.”

See all refractive results in an easy-to-read graphical display via the console.

Print out subjective refraction results directly from the console- or, send it off to your EHR network.

Connect your CDR refractor to the junction box (seen below) for direction integration and communication with Huvitz lensometers, acuity charts, and PC computers. 

Yes, every BUZZ Phoropter/Digital Refractor instrument ships with all accessories standard.

The Huvtiz CDR systems are designed to integrate through use of a “Junction Box” which allow the Phoroter head to communication with the Phoropter console and vice-versa. The automated acuity chart will also connect for integration through the console, and additional PCs can also be linked.

*sigh* It depends. It DOES have the capability to do so, but like we always say, check with your EHR company prior to see if a gateway has been previously written.
