A spectral domain optical coherence tomography system is integrated with an optical reflectometer to provide dualfunctional eye measurement. The system is capable of performing anterior segment imaging and tear film thickness evaluation at the same time. The axial resolution of the anterior segment imaging is 6μm while for tear film thickness measurement the resolution is about 21 nm. We use the integrated device to examine a model eye with artificial tear film. Structures such as the cornea, the ciliary muscle, and the front boundary of the crystalline lens are clearly visible. Artificial tear film thickness is determined simultaneously with anterior segment imaging. The integrated device is also flexible for separated anterior segment imaging or tear thickness evaluation.
