Abstract:
Objective To develop a spectral-domain optical coherence tomography(SD-OCT)system , for precisely imaging the accommodation of the anterior segment of the human eye. Methods Design the SD-OCT system based on two Michelson interferometer by using the basic principal of weak coherent light interference and modular design of dual channel dual focus. Results The system can provide simultaneous cross-sectional imaging of al the surfaces of the anterior segment of the eye including the cornea, anterior chamber, anterior and posterior surfaces of the crystal ine lens. Thus, the dynamic change of modification of the curvatures can be calculated in real time. Conclusions The system was successful y tested in imaging accommodation, with high resolution and non contact. The preliminary results demonstrated the feasibility of this novel approach to measure the eye parameters.
