1. A method comprising:
receiving an indication to initiate a first optical coherence tomography (OCT) scanning of an eye;
initiating, based on the received indication, the first OCT scanning of the eye;
generating, based on the first OCT scanning, a first OCT image of the eye;
detecting, based on the first OCT image, a retinal pigment epithelium (RPE) of the eye and a fovea in the eye;
based on the detecting, causing a first enhanced OCT image to be displayed to a user, the first enhanced OCT image displaying:
a first virtual marker segmenting at least a portion of the detected RPE, wherein the first virtual marker is a curvilinear line, and
a second virtual marker, wherein the second virtual marker visually identifies a location of the detected fovea, and wherein the second virtual marker is a radial line through the location of the detected fovea;
detecting, based on the first OCT image, an abnormal macular anatomic configuration in the eye; and
in response to detecting the abnormal macular anatomic configuration, transmitting an alert to the user advising against using a contrast decreasing multifocal intraocular optical lens (IOL).
