Embodiment Construction

[0067] The technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0068] An embodiment of the present invention provides an ophthalmology measurement system (hereinafter referred to as "system"), which is used to detect the eye E to determine multiple parameters of the eye E, such as the axial length and corneal curvature of the eye E , anterior chamber depth, white-to-white distance, pupil diameter and other parameters. The system is based on OCT technology. As one of its multiple technical effects, the system can realize the application of spectral domain OCT technology to...

Abstract

An ophthalmic measurement system and method are used for detecting checked eyes. The ophthalmic measurement system includes a switching scanning element, an eye anterior segment light path assembly, an eye posterior segment light path assembly, a light splitting element and a main body module. An optical path can be switched between the eye anterior segment light path assembly and the eye posterior segment light path assembly by the switching scanning element, and an eye anterior segment and an eye posterior segment of the checked eyes are scanned. The invention provides another technical scheme which can realize the switching of scanning of the eye anterior segment and the eye posterior segment of the checked eyes to determine the axis length of the checked eyes, and the disadvantages ofcomplex structure and high cost of the prior art are overcome.

Description

technical field [0001] The invention belongs to the field of ophthalmology inspection equipment, and in particular relates to an ophthalmology measurement system and method. Background technique [0002] Cataract surgery, corneal refractive surgery, and the effective prevention and treatment of juvenile myopia require accurate measurement of multiple parameters of the eye, such as corneal anterior and posterior surface curvature, corneal thickness, anterior chamber depth, lens thickness, lens anterior and posterior surface curvature, ocular axial length, White-to-white distance, pupil diameter, etc. In the prior art, ultrasonic technology is the most widely used method for obtaining the multiple parameters, but its measurement accuracy is low. [0003] In view of the shortcomings of the ultrasonic technology, an ophthalmic measurement system based on OCT (Optical Coherence Tomography, optical coherence tomography) technology has been developed to obtain the multiple paramet...
