A multifunctional ophthalmic measuring device and a method for testing different parts of the human eye

Abstract

The invention discloses a multifunctional measuring apparatus for the ophthalmology department. The multifunctional measuring apparatus for the ophthalmology department comprises an OCT system light source, an optical fiber coupler, a detection system, a control system, a sample arm component, a reference arm assembly and an optical length compensation module. The optical length compensation module is matched with eye anterior and posterior segment scanning member to change the optical length of an OCT system so that OCT images of different portions of the human eyes can be formed and OCT imaging switching between the portions can be achieved. The invention further discloses a method for testing different portions of the human eyes through the apparatus. The method includes the steps that an optical path system for OCT imaging of different portions of the human eyes is arranged, and the system comprises the optical length compensation module; the optical length compensation module is sequentially placed on a principal optic axis of an OCT imaging optical path, and OCT imaging of different portions of the human eyes can be achieved by changing the optical length. Through the multifunctional measuring apparatus for the ophthalmology department and the method for testing different portions of the human eyes, numerous parameter data of the human eyes can be obtained through one measurement, working efficiency is improved, and cost is reduced.

Description

technical field [0001] The invention relates to the field of optoelectronics, in particular to an OCT system capable of switching and measuring different parts of the human eye and a corresponding measuring method. Background technique [0002] Nowadays, more and more elderly people suffer from cataract eye disease, and implanting intraocular lens is an effective solution for cataract widely used at present. However, the calculation of intraocular lenses requires more parameters, such as the curvature of the front and rear surfaces of the cornea, corneal thickness, depth of the anterior chamber, lens thickness, curvature of the front and rear surfaces of the lens, axial length of the eye, white-to-white distance, and pupil diameter. There are many parameters to be measured, but the above complete data can only be obtained after the detection of multiple medical devices. [0003] Optical coherence tomography (OCT, Optical Coherence Tomography) is an emerging optical imaging ...
