Abstract
Clinically, the primary means for cataract evaluation is by slit-lamp examination using a subjective grading system[1]. A new noninvasive technique called Optical Coherence Tomography (OCT) has recently been used to image the anterior segment and provide the examiner with an additional assessment of cataract formations in the lens. Similar to ultrasound B scan imaging, OCT provides two-dimensional tomographs of optical reflectivity by transverse scanning the optical beam during sequential ranging measurements.
