Abstract
A visualization system for an ophthalmic procedure on a target eye, e.g., lens replacement surgery, includes first and second light sources respectively operable for directing visible and NIR light toward the target eye. A hot mirror directs reflected light from the eye along two paths, i.e., a visible light path for reflected visible light and an NIR light path for reflected NIR light. First and second cameras are respectively positioned in the visible and NR light paths to detect the reflected visible or NIR light and output a visible or NIR image. An electronic control unit (ECU) executes a method to detect a perimeter edge of an imaged portion of the target eye in the NIR image using edge detection logic, merges the visible image with the NIR image to construct a combined image, and indicates the perimeter edge in the combined image.
