Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.
[0038] The embodiments of the present invention will be described below according to the overall structure of the present invention.
[0039] A photoelastic imaging-assisted orthokeratology fitting device, such as figure 1 , figure 2 , image 3 and Figure 4 As shown, it includes the bottom plate 1, the moving seat 2 and the detection mechanism 3 on the top thereof. Both sides of the top end of the bottom plate 1 are fixed with fixed columns 4, and brackets 5 are slidably connected to the middle positions outside the two sets of fixed columns 4;
[0040] Both sides of the bracket 5 are fixedly pr...

The invention discloses an orthokeratology lens fitting device based on photoelastic imaging assistance, and relates to the technical field of orthokeratology lens fitting. The orthokeratology lens fitting device comprises a bottom plate, a movable seat and a detection mechanism at the top of the movable seat, wherein fixed columns are fixedly arranged on two sides of one end of the top of the bottom plate. When the chin of a patient presses a bracket downwards, the bracket descends to drive a first connecting plate and a first telescopic rod to descend, so that first piston plates press downwards in a first air cylinder, air at the bottom end in the first air cylinder enters a second air cylinder through a connecting pipe under the pressing acting force of the first piston plates, and the entering air acts on the top of a second piston plate; so that the second piston plate moves in the second air cylinder from top to bottom; and a second telescopic rod descends to drive a fixing plate and a side limiting plate to descend through a second connecting plate, so that the fixing plate and the side limiting plate can press down and fix the top end of the head of the patient to a certain degree. The problem that the detection result is incorrect due to the fact that the patient shifts or even shakes in the detection process is effectively solved.
Description
technical field [0001] The invention relates to the field of orthokeratology fitting technology, in particular to a photoelastic imaging-assisted orthokeratology fitting device. Background technique [0002] Orthokeratology lenses, commonly known as OK lenses, are rigid contact lenses worn at night to achieve clear vision without wearing glasses during the day. Wearing them for a long time can delay the development of myopia. Through the pressure on the surface of the lens and the adsorption force of tears, the redistribution of the cells on the front surface of the cornea is changed, so that the central part becomes thinner (the curvature becomes smaller and flatter), and the curvature of the side center becomes larger and steeper, thereby changing the defocus state of the peripheral retina. Change from hyperopic defocus to myopic defocus, thereby achieving the effect of inhibiting the increase of eye axis and delaying the growth of myopia. [0003] Before wearing orthoker...
