Embodiment Construction
[0041] The present invention will be further described below in conjunction with specific embodiments. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.
[0042] Below in conjunction with accompanying drawing and embodiment the patent of the present invention is further described.
[0043] Such as figure 1 As shown, the present invention provides a method for detecting intraocular astigmatism and astigmatism axis, comprising the following steps:
[0044] Step 1: Use retinoscopy or computer optometry to obtain the total eye diopter, convert the total eye diopter from the plane of the glasses to the cornea plane, and obtain the total astigmatism of the whole eye from the diopter of the cornea plane; the specific process is as follows:
[0045] 1.1 Cross transformation of the panocular diopter of the spectacle plane: the panocular diopter of the spectac...
