What are these measurement machines used for?

iTerminal is the auto measuring tool used to measure the position of wear data for every patient.  i.e. seg ht. /  P.D.  / Panto / Wrap / back vertex distance.  It also acts like a smart mirror to present the options and benefits of AR, Transitions, tints.

The iProfiler is an auto refractor / keratometer / corneal topographer / and wave front abborometer.  The measurements from the iProfiler are combined with the Doctors subjective refraction and the result of this merger is the iScription.

The i.Scription SW provides tools for the ECP to review the information from the i.Profiler plus and image simulations based customer data for easy patient communication.

i.Profiler Plus: FAQs

What is i.Profiler plus®?
i.Profilerplus is a sophisticated, full-featured “3-in-1” system that incorporates the industry-leading ATLAS 9000 corneal topographer, wavefront aberrometer, and autorefractor. The i.Profilerplus quickly and easily measures the ocular wavefront aberrations and refractive status of the eye as well as the topography and aberrations of the cornea. These measurements can also be presented graphically in an extensive array of contour maps and vision simulations.

What is the purpose of i.Profiler plus ?
The i.Profilerplus offers a variety of diagnostic capabilities that are invaluable tools in a variety of clinical applications: evaluating the complete refractive status of the eye, including low- and high-order wavefront aberrations; fitting soft and rigid contact lenses; monitoring ocular disease processes; and managing or co-managing refractive and surgical interventions. Ocular wavefront data captured by the i.Profilerplus is also used to calculate an i.Scription, which is a wavefront-guided spectacle correction that offers enhanced visual performance over a range of viewing conditions.

What are wavefront aberrations?
Wavefront aberrations represent an increasingly common technique for characterizing the focusing errors of the human eye and other optical devices. Wavefront aberrations are generally categorized as either low-order aberrations or high-order aberrations. Low-order aberrations are associated with the traditional refractive errors of the eye, or the sphere power and cylinder power of the prescription. High-order aberrations represent more subtle focusing errors that can also affect vision quality, particularly at larger pupil sizes. Although it is not possible to correct the high-order aberrations of the eye with a spectacle lens, the sphere and cylinder powers of a traditional prescription can be fine-tuned to minimize the effects of high-order aberrations on vision quality.

How do high-order aberrations impact vision?
High-order aberrations create additional image “noise” that degrades vision quality and reduces retinal image contrast, particularly at larger pupil sizes. High-order aberrations can also produce certain glare phenomena around lights and other bright objects at night, including “halo” and “starburst” patterns.

What technology does the i.Profilerplus use to measure the aberrations of the eye and cornea?
The i.Profilerplus measures wavefront aberrations using a Shack-Hartmann wavefront sensor. It measures the corneal topography of the eye using a videokeratography system with an integrated Placido disk.

Why are the results from the i.Profilerplus superior to those of a conventional autorefractor?
Conventional autorefractors can only measure the overall refractive power of the eye, typically over a small, central region of the pupil. They cannot account for local variations in refractive power across the eye due to the presence of high-order aberrations. The i.Profilerplus measures the distribution of the refractive power across the entire pupil, permitting more accurate calculation of the entire refractive status of the eye.

How long does the measuring process take?
The complete measuring process takes less than 1 minute for both eyes.

How difficult is the device to operate?
The process is fully automatic and can easily be performed by staff with minimal training.

Can the i.Profilerplus be used to measure children?
Yes. Thanks to its measuring speed, the i.Profilerplus is ideal for the measurement of children who are capable of maintaining fixation on the test image for a short period of time.

What data does the i.Profilerplus collect in keratometer mode?
The i.Profilerplus measures the central and peripheral corneal radii as well as the complete corneal topography of the eye by means of a videokeratography system with integrated Placido projector.

Is the i.Profilerplus required to prescribe i.Scription lenses?
Because i.Scription relies on measurements of the wavefront aberrations of the eye, a wavefront-sensing aberrometer is required. Currently, the i.Profilerplus is the only aberrometer that has been qualified by Carl Zeiss Vision to work with the i.Scription calculation engine.
