CustomVue Technology

Aligning the treatment plan to the patient's eye is the important third step in the CustomVue procedure. The STAR S4 with Iris Registration and Activetrak help you maintain centered ablations with our exclusive alignment technologies:

Iris Registration
Achieve a new level of precision in treatment alignment with Iris Registration (IR) - the first FDA-approved, fully automated, non-contact method of alignment of the correct CustomVue treatment to the corneal site. Using sophisticated algorithms and multiple reference points on each iris, IR ensures delivery of the treatment to the correct area of the cornea. It also enables you to instantly re-register in the event of intra-operative cyclotorsional movement. In addition, IR also correctly centers treatment independent of pupil center migration. Complete alignment confidence delivered. Automatically.

Features:

• Greater alignment accuracy
• Non-contact method of aligning treatment
• Images iris under flap
• Re-registration capability during treatment

Benefits:

• Achieves cyclotorsional alignment by linking diagnostic
  information with laser treatment
• Creates a new level of confidence in the accurate placement of the correct treatment on the patient’s eye
• Minimizes human error in aligning treatment
• Provides the physician with the ability to compensate for intra-operative cyclotorsional movement

3-D active eye tracking
Tracks x, y, and z axis intra-operative movement of the eye

ActiveTrak Automatic Centering
Locates, and then automatically sets the treatment center to the center of the pupil.

1.5mm passive limits
If the patient's eye moves 1.5 mm from the established center point in any direction, the tracker pauses the laser, resuming only after the eye has returned to within acceptable limits.

Virtual reticle
A virtual grid overlay on the eye provides real-time, dynamic feedback to allow you to monitor treatment progress and eye position.
