Scheimpflug Slit-Lamp Photographic Characterization of the Aging of the Human Crystalline Lens and the Development of Presbyopia
The slit-lamp biomicroscope is essential in the clinical evaluation of the human ocular anterior segment. A narrow slit of intense white light is shone into the globe, illuminating a thin optical section of the anterior segment, and the illuminated section is examined at an angle through a icroscope. While qualitatively useful, the resultant image is quantitatively severely distorted by the angle of observation, which is a variable projection of the true spacings, and by the passage of the scattered light through the cornea, a strong and sharply curved refractor.
