Cornea surface contour obtaining system and use method thereof

Abstract

The invention provides a cornea surface contour obtaining system and a use method thereof. The system comprises a shell, an optical projection unit, an optical shooting unit, a control panel and a display screen; the optical projection unit is arranged in the shell and used for projecting tandem arranged light rays into the human eye; the optical shooting unit is arranged in the shell and used for collecting light rays reflected from the human eye; the control panel is arranged in the shell and connected with the optical projection unit and the optical shooting unit; the display screen is arranged in the shell and connected with the control panel and the optical shooting unit. The cornea surface contour obtaining system and the use method thereof have the following advantages that surface contour data of the front surface and the rear surface of a cornea are obtained simultaneously, and the surface contour accuracy is greatly improved, particularly, in the central area of the cornea; complex rotary motion is not needed, tomoscan in all directions can be achieved by only depending on control over micromirror devices, the scanning speed is high, and the cornea surface contour data can be rapidly obtained; the size is small, and carrying and using can be convenient for a doctor.

Description

technical field [0001] The invention relates to a system and method for ophthalmological optical examination and acquisition of corneal related data, in particular to a corneal surface acquisition system and its application method. Background technique [0002] In medical testing, the existing equipment for corneal surface acquisition is often relatively large in size, and doctors cannot use it quickly and conveniently in occasions such as ward rounds and rounds, and the accuracy of existing equipment for the acquisition of corneal surface data It is not high, and only the data of the front surface can be obtained, and the surface data of the rear surface cannot be obtained. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a corneal surface acquisition system and its use method which solve the problems of large volume and non-portability of existing corneal surface acquisition data. [0004] In or...
