Abstract
Accommodation is the process by which the optical power of the eye changes in order to shift focus from far to near objects. These changes in ocular power are the result of changes to the shape of the crystalline lens due to the contraction of the ciliary muscle. The goal of this project is to develop and validate a high-resolution, dynamic, optical imaging instrument to measure the optical and physical changes that occur in the eye during accommodation. The system will consist of an autorefractor to measure ocular power, a visual fixation target to stimulate accommodation, and OCT system to measure the crystalline lens and other key ocular dimensions. With this system, the next step will be to measure human subjects and analyze their individual accommodative responses. The individual accommodative responses will correlate ocular power changes with changes in ocular dimensions.
