Systems and methods for stabilization and alignment of vision correction

Abstract

A patient is provided with a fixation stimulus comprising a plurality of colors, which helps to entrain the fixation of the subject on a fixation target, calm the subject, and provide verification that the patient is appropriately aligned. A processor can be configured to cycle the fixation stimulus through the plurality of colors at regular intervals over a plurality of cycles. A parallax imaging system such as a stereoscopic microscope is used to generate images that combine the left and right views, which can improve alignment and centration. Alignment targets can be provided that allow the use of vernier acuity to determine alignment with the subject. The fixation stimulus and alignment system can be used with many optical therapies, such as contact lenses and laser vision correction.
