Problems solved by technology

[0003] After the intraocular lens is made, it needs to be put into the human eye for use. During the insertion process, the placement of the intraocular lens is very important. The accurate placement of the intraocular lens can improve clarity and reduce side effects at the same time. And the impact of inflammation on the eyes, and the different angles of intraocular lens placement involve many variables. The existing medical staff usually wear a magnifying glass to adjust the position of the intraocular lens through observation, and the adjustment is not accurate enough.

Embodiment Construction

[0012] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0013] The astigmatism intraocular lens axis display system includes a host system and a display system. The host system includes an imager, an analog input module, a calculation module, and an output module. The display system includes a display control adapter and a display. The output module Connected with the display control adapter, the analog input module includes the angle between the axis and the corneal astigmatism axis, the calculation module outputs the residual astigmatism and the angle between the original astigmatism, and the display shows the axis rotation Schematic diagram, axial map of residual astigmatism, amount of residual astigmatism, and angle between original astigmatism.

[0014] The calculation formula in the calculation module is C=2Fsinα, tanθ=(sinα-1) / cosα, wherein C is the amount of residual astigmatism, α is the angle between the...

Abstract

The invention discloses an astigmatic intraocular lens axial position display system, and the system comprises a host system and a display system; the host system comprises an imager, an analog quantity input module, a calculation module and an output module; the display system comprises a display control adapter and a display, and the output module is connected with the display control adapter. The analog input module comprises an included angle between an axial position and a corneal astigmatism axial position, the calculation module outputs a residual astigmatism amount and an included angle between the residual astigmatism amount and original astigmatism, and the display displays an axial position rotation diagram, a residual astigmatism axial position diagram, the residual astigmatism amount and the included angle between the residual astigmatism amount and the original astigmatism. Compared with the prior art, the device has the advantages that all adjusted variables can be displayed through the displayer after adjustment, the schematic diagram of the placement position of the intraocular lens is displayed, images and parameters are combined clearly, the adjustment of medical staff is facilitated, and the placement accuracy of the intraocular lens is improved.

Description

technical field [0001] The invention relates to the technical field of intraocular lens axis display, in particular to an astigmatism type intraocular lens axis display system. Background technique [0002] Intraocular lens refers to a special lens made of artificial synthetic materials, and its components include silica gel, polymethyl methacrylate, hydrogel, etc. The shape and function of the intraocular lens are similar to the lens of the human eye, and it has the characteristics of light weight, high optical performance, non-antigenic, inflammatory, carcinogenic and biodegradable. After cataract surgery, the cloudy lens is removed, and the artificial lens is implanted in the eye to replace the original lens, so that external objects can be focused and imaged on the retina, and the surrounding scenery can be seen clearly. [0003] After the intraocular lens is made, it needs to be put into the human eye for use. During the insertion process, the placement of the intraocu...
