A slit lamp provides a three dimensional view of the anatomical parts of the eye and magnification of these different structures through the use of a beam of light during an optometric exam. Optometrists use slit lamps to identify disorders, infection or any other complications offering a more interactive approach to documenting an eye exam.
There are several types of optometric slit lamps including conventional biomicroscope, portable slit lamps, and digital slit lamps. Considerations include magnification, illumination, slit width/length, and slit aperture.
