How does BuzzOptics judge instrumentation?

Prior to offering a specific instrument in the Buzz marketplace, our team throughly tests and evaluates the device, and performs testing in real clinical scenarios to offer you the best glimpse of how the instrument will perform.  Buzz then awards the specific instrument two different ratings and scores.


The Star Ranking:

Each device is awarded a ranking, detailed in a score from one to five stars. The higher the score, the more likely we would recommend the unit for purchase. The lower the score- the inverse is true. Our stars are awarded based on performance intended for clinical use only, and are not representative of:

  • Price; its market value position, or whether it appears to be an attractive price point.
  • Manufacturer name recognition, warranty offerings, manufacturer support, or availability.
  • Competitiveness of other models.

BuzzOptics does not sell instrumentation that ranks at or lower than 2 stars based on our evaluation.


Category Ratings:

Each device is given a rating for four individual categories. Each of these represent, what we believe, to be the most important traits considered for an ophthalmic instrument investment. These categories and their meanings are detailed below:


Robustness: Typically related to the instrument’s age, Robustness is a measure of how durable and long-lasting we believe the unit to be. The higher the rating, the longer the device should provide utility without breaking down or requiring maintenance. In general, older instruments receive lower robustness ratings.

Accuracy: A rating of the accurateness per the objective results provided. Accuracy also refers to the instrument’s consistent ability to provide reliable data. A low rating would indicate the unit is inconsistent, or lacks accuracy altogether. This rating is not applicable for instruments that produce images or other results needing subjective review, and are rated under Aptitude (see below).

Aptitude: A rating for instruments that produce subjective-based data only, Aptitude refers to the instrument’s technological ability to produce information, data, images, or other information that advances diagnostic or refractive capability. An instrument with a high ranking in this category indicates advanced capability to construct state-of-the-art presentations that aide in the diagnostic process.

Comfort: An overall rating of how comfortable and easy-to-use the instrument is for both patient and operator. This may refer to patient and operator position, or a subjective rating of how intimidating the instrument may be for all involved.

Design: A general ranking of how appealing or attractive the unit appears based on its exterior presence. This also considers the relationship between design and functionality. An instrument that looks great but has an LCD screen monitor in an obscure place, may struggle in this category.
