Modern ophthalmology favors complete examination of the eyes, including routine slit-lamp study with the usual refraction and ophthalmoscopy. This trend has led to more convenient and centralized arrangements of the necessary instruments. Various slit-lamp arms on instrument stands enable the slit lamp to swing easily into position for use without moving the patient after refraction. However, adjustment of the height of the conventional slit-lamp arm is limited. The arms are high enough to require the physician to sit on a high stool and the patient in a high examining chair of the pump or motor-driven type.
It would seem more desirable to seat the patient in a chair of conventional height. The refraction and slit-lamp examinations could then be performed at a low enough level to permit the physician to be seated comfortably in an ordinary executive type chair.
