PROBLEM
Holding a patient in a stationary position while examing the eye requires adaptive technology. Often during an exam, doctors require that patients respond to questions. Traditional eye exam methods position the head and face into a chin rest. As a patient speaks, the position of the head changes due to the opening and closing of the mouth.
SOLUTION
An ophthalmologic apparatus can solve positioning problems when examining a subject’s eye. The apparatus includes a surface coming into contact with the forehead of the subject; and two nodes coming into contact with the cheeks of the subject. Both the right and left nodes of the device contact each cheek, wherein a mechanism automatically adjusts to accommodate the various widths and heights of the human face by opening and closing.
