The ultrastructure of the human lens capsule and zonular attachments was studied using scanning electron microscopy. The capsule was found to have two components; an organized mass of undulating, roughly parallel fibrils and a granular component. The undulation of the capsular surface and filament organization was much less evident near the anterior pole. The zonules were also found to be fibrillar and easily distinguishable from the capsular network. The three-dimensional aspects of the association between the zonules and the capsule as seen in these studies appear to meet the requirements of accommodation.
