Claim 16:
17. A method of ophthalmic optical coherence tomography (OCT) comprising:
applying an OCT scan to an anterior segment of an eye;
constructing an image based on data acquired by the OCT scan;
detecting an artifact along an A-scan direction by analyzing the image;
performing alignment based on the artifact;
detecting a corneal image by analyzing the image;
judging whether an intersection of the artifact and the corneal image is located within a predetermined area in an image frame;
calculating an image quality evaluation value of the image; and
applying an OCT scan of a predetermined pattern to the anterior segment, if the intersection is judged to be located within the predetermined area and the image quality evaluation value is equal to or greater than a predetermined threshold.
