Device for detecting elasticity of crystalline lens through optical coherence elastography

Abstract

The invention relates to a device for detecting crystalline lens elasticity imaging, in particular to a device for detecting crystalline lens elasticity through optical coherence elastography The device for detecting crystalline lens elasticity through optical coherence elastography is good in comfort level and accurate in detection result. The device for detecting elasticity of crystalline lens through optical coherence elastography comprises a base, first sliding rods, a sliding block, a first support, a first sliding sleeve, a connecting block, a hollow frame, a mark block and a marking rod, the first sliding rods are symmetrically arranged on the base, the sliding block is slidably connected between the upper portions of the two first sliding rods, and the first support is arranged on the upper portion of the sliding block; a first sliding sleeve is arranged on the upper portion of the sliding block, a marking rod is slidably connected between the first support and the first sliding sleeve, a hollow frame is arranged on the upper portion of the first support, and a marking block is slidably arranged in the hollow frame. By arranging the buffering mechanism, the comfort degree of crystalline lens elasticity detection is improved.

Description

technical field [0001] The invention relates to a device for detecting lens elasticity by imaging, in particular to a device for detecting elasticity of lens by optical coherent elastography. Background technique [0002] Presbyopia is a degenerative disease, which is generally more common in middle-aged and elderly people. People's vision generally begins to decline from the age of 35. After the age of 40, it will gradually appear that it is more difficult to read at close range. The reason for this symptom is mainly due to the increasing age, the hardness of the lens gradually increases, the elasticity weakens, the contraction ability of the ciliary muscle of the eyeball decreases, the adjustment ability of the eyes decreases, and the near vision decreases. In order to carry out targeted treatment for different degrees of weakening of presbyopic lens elasticity, it is necessary to detect the elasticity of the lens. The existing elasticity detection devices generally use p...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an optical coherence elastography device for detecting the elasticity of the lens with better comfort and more accurate detection results, which solves the problem that the existing elasticity detection device generally requires presbyopia patients to look at the visual acuity test chart. For detection, this detection method has the problem that the detection result is not accurate enough
