Section I. EYE SURGERY 1-1. INTRODUCTION
a. General. The anatomy, physiology, and the location of the eye make surgery upon the eye a highly specialized field of surgery. Therefore, procedures done by the specialist when assisting with eye surgery differ from procedures used for other surgical specialties. However, the principles of asepsis and safe, skillful care apply as in all other surgery. The ensuing text presents a discussion of the necessary considerations that are applicable in the majority of cases in this specialty.
b. Special Care of Instruments. The specialist is to use exacting care when working with instruments for eye, ear, nose, and throat surgery because most of these instruments are delicate. Sharp surfaces of these instruments must be preserved to ensure the success of the operative procedure. The specialist is to follow local policy in the care and handling of these instruments.
c. Anatomy and Physiology of the Eye. The eye is also referred to as the eyeball or globe. In the adult, it is slightly less than one inch in its longest diameter. See figure 1-1 for parts of the eye.
