Eye tracking has become an essential standard component for refractive surgery lasers for the precise and immediate compensation of fast and unpredictable eye movement during surgical treatment of the eye.
SMI is the market leader in this field and offers complete OEM eye tracking systems for refractive surgery, based on SMI's high performance DSP processing and our own camera technology.
The customization of our own technology to a customer's existing or future system environment is an optimized and well-established process at SMI: From optics, illumination, mechanics, hardware and software architecture, right up to software algorithms, software interfaces and production calibration, you will find we are the experts at SMI.
For example, the new kHz eye-tracking system dramatically reduces dynamic positioning errors during treatment by measuring such eye features as pupil or limbus, iris and blood vessels with an accuracy down to 5 µm and superior short latencies as low as 1 ms.
The modular concept of the kHz eye-tracking system allows extensions with dynamic cyclotorsion compensation for rotational movements of the eye, limbus tracking for compensation of pupil center shifts, 6D tracking for compensation of all movements of the eye (see 6D Eye Tracking for further details) and static registration of coordinate systems between diagnostic and treatment devices (see Registration for more information).
As you can see, refractive eye tracking means more than locating the pupil, if you want to improve your clinical outcome and workflow.
