The US Food and Drug Administration recently approved a first of its kind of technology for LASIK eye surgery, known as Advanced Control Eyetracking (ACE), for the Technolas LASIK platform. Eyetracking allows lasers used during LASIK surgery to compensate for eye movements during the procedure, thus adding an important level of assurance. However, no eyetracker has been able to adjust for subtle rotations of the eye that can occur during the laser treatment – that is until now. >> read more <<
Eye Tracking In Range: This new eyetracker locks on to the eye's unique iris pattern before the laser treatment begins, and then monitors the pattern throughout the procedure. When the eye moves during the procedure (the eye tracker monitors eye movement to the left, right, up, down and as it twists (torsion)) the direction of laser pulses is nearly instantaneously adjusted accordingly. No other LASIK system available in the US can compensate for these movements during the LASIK treatment.
Out of Range: As an added safety measure, while the eye tracker is monitoring movement of the eye, if the movement falls completely out of range the laser pulses stop until the eye is repositioned. This ensures that each laser pulse of the LASIK treatment is delivered to its intended location on the cornea.
