VIP®-400 Pupillometer

Very Accurately Measures Pupil Size Under

Various Light Conditions

Enables clinician to make best possible medical decision for LASIK and premium IOL patients based on pupil size, stated daily activities, and patient preferences.

Portable, battery operated, hand-held device

Very accurately measures pupil diameter (±0.03 mm)

“Light Off” setting, 2-second measurement of pupils at different background illuminations

“Variable” setting measures scotopic, low mesopic, and high mesopic pupil sizes in one 12-second sequence to simulate light conditions patient may experience in daily life

Ergonomic design

Wireless charging

Download data via USB

“The NeurOptics® Pupillometer…is very compact, simple to use, reasonably priced and gives accurate automatic readings. An accurate instrument for measuring the scotopic pupil is essential for refractive surgeons.”

–James Salz, M.D.

Technology Produces Reproducible Measurement Results

Testing has shown that the NeurOptics® Pupillometer is consistent from unit to unit and operator to operator. In fact, the NeurOptics Pupillometer has the highest accuracy and lowest error of all commercially available pupillometers1, while at the same time being the most economical hand-held infrared device.

 

The key to the reproducibility in measurement is the use of VIP® (Vertex Invariant Pupillometry®) technology developed by NeurOptics. This system compensates for the approximate 12 mm range in vertex distance2 that may lead to inaccurate pupil measurement (error up to 20%), producing accurate measurements that are not affected by vertex distance3.

Simple to Use and Operate

One-button activation

No calibration required

Data is stored on the device and can be recalled, downloaded and/or printed

Video of the measurement can be played on the device’s screen

3. The pupil is never at rest, and therefore a single, static, measurement is unlikely to be an accurate assessment of a pupil’s true amplitude or range of diameter. To compensate for pupillary unrest, NeurOptics employs a dynamic measurement system which captures 30 pupil positions over an approximate 2-second scanning period, thus producing the weighted average pupil size and standard deviation.

  • “From a medical-legal perspective, it’s not only important to show that you put thought into it and have numbers that you can refer back to but also defend that those numbers are accurate and reproducible.”

  • “The simplicity and versatility of this instrument is tremendous to us, in the sense that in our single clinic we can apply it to our cataract patients, our phakic IOL patients, our hyperops [farsighted patients]undergoing LASIK, as well as our patients that are seeking monovision. And all of that can be done because of the fact that it’s so easy to use and so incredibly accurate.”

  • “It was really easy to train my staff to use this. It took about five minutes per staff member which is faster than learning the autorefractor and certainly much faster than learning the topographer so I found it very easy to implement in the office.”
