Abstract
An ophthalmic visualization system includes a rear illumination system, to generate and to project a rear illumination light onto a retina of an eye that has an intraocular lens (IOL) implanted into the eye, so that the rear illumination light reflects from the retina as a reflected illumination light, wherein a central portion of the reflected illumination light propagates through the IOL to form an IOL-focused illumination light, and a peripheral portion of the reflected illumination light propagates around the IOL to form a peripheral illumination light; an optic, to receive the IOL-focused illumination light and the peripheral illumination light from the eye, and to transmit the received illumination lights; an aperture slop, to stop the transmitted peripheral illumination light, and to allow the IOL-focused illumination light to pass through; and an imaging system, to form an isolated IOL image based on the transmitted IOL-focused illumination light.
