Utilizing the benefits of the red, flashing fixation LED maximizes the patient’s ability to cooperate during surgery because they are far more comfortable than if looking at the conventional coaxial halogen microscope lights with a dilated pupil. When the surgeon asks the patient to look at the blinking red light, the eye is in the ideal position for centration of the capsulorhexis, astigmatic keratotomies or IOL location.
The ring light array provides visualization of corneal astigmatism with typical Placido ring accuracy. This is a learned skill for most surgeons, and generally accurate down to a diopter or two. This system improves surgeon confidence and may also improve outcomes. Errors are minimized when aligning Toric IOL’s, performing LRI’s and other procedures such as tensioning sutures during corneal transplantation (keratoplasty).
Other benefits not related to astigmatism management include multifocal IOL’s, which allow for concentric alignment utilizing the placido rings superimposed on the multifocal IOL rings.
The majority of precision diagnostic instruments (e.g. topographers and aberrometers) utilize a fixation target, so this surgical system is compatible with diagnostic approaches.
