The invention discloses an ophthalmic measurement system for inspected eye detection. The system comprises a main body module, a reference plane, a switching scanning element, an anterior segment light path assembly, a posterior segment light path assembly and a light splitting element, the anterior segment light path assembly, the posterior segment light path assembly and the light splitting element are all arranged on the reference plane, and the switching scanning element can rotate around a fixed shaft, so that switching between the anterior segment light path assembly and the posterior segment light path assembly is realized, and the anterior segment and the posterior segment of a detected eye can be horizontally scanned. According to the invention, switching between anterior segmentscanning and posterior segment scanning of the detected eye can be realized based on the spectral domain OCT technology so as to determine the axial length of the detected eye, the defects of complexstructure and high cost in the prior art can be overcome, and horizontal scanning can be realized.
