User-proposed entry field(s) for customized data analysis/presentation
View Patent ↗One embodiment of the present invention is a method to not limit the device's manipulation of the data to that of the manufacturer, but to allow greater freedom for customization by the individual user for their preference.
1. An apparatus comprising: a wavefront sensor configured to capture raw wavefront aberration data values of an eye; a user-input device configured to allow an end user to select one of a plurality of predefined processes, as algorithms, filters and analyses, where a selected predefined process manipulates raw wavefront aberration data values to assess or alter the raw wavefront aberration data values and outputs resultant data in various forms; a non-transitory computer readable storage device holding one or more raw wavefront aberration data values, captured by the wavefront sensor a measurement device, and program code; a controller, coupled to the storage device and user-input device configured to execute the program code to assign one or more raw wavefront aberration data values a the user-selected process, algorithm that processes one or more of the variables to execute the user-selected process to assess or alter the one or more raw wavefront aberration data values and to output the resultant data.
2. The apparatus of claim 1 further comprising:
a display device coupled to the controller and configured to display resultant data output by the controller.
3. The apparatus of claim 1 where:
the raw wavefront aberration data values are spherical and cylindrical refractive error values.

the raw wavefront aberration data values are high-order aberration values.
5. The apparatus of claim 1 where:
the raw wavefront aberration data values are coma, trefoil and spherical aberration values.
6. The apparatus of claim 1 where:
the raw wavefront aberration data values are the measured spherical refractive error (u) and the measured cylindrical refractive error (v) of an aphakic eye, where the selected process manipulates the raw wavefront aberration data values to determine a resultant value of w=0.07(u+0.5v) 2 +1.27(u+0.5v)+1.22, with w being the power of an intraocular lens (IOL) and where u, v, and w are output by the controller in the form of a table.
7. The apparatus of claim 1 where:
the selected process manipulates a polynomial of a variable and a raw wavefront aberration datum value is assigned to the variable.
8. An apparatus comprising:
a sub-wavefront focusing lens configured to focus a sub-wavefront, being an incident portion of a wavefront generated by a light source, to an image spot located on a focal plane;
a sequential wavefront scanning device configured to sequentially project different portions of an incident wavefront on the sub-wavefront focusing lens;
a variable aperture configured to control the size of the sub-wavefront;
a position sensing device, located substantially at the focal plane of the sub-wavefront focusing lens, configured to indicate the location of the image spot on the focal plane;
a controllable wavefront offsetting element positioned to intercept the portion of the wavefront before it is incident on the wavefront sensor;
a user-input device;
a non-transitory computer readable storage device holding one or more data values captured by a measurement device and a program;
and
a controller, coupled to the controllable wavefront offsetting element, the user input device and the storage device, configured to control the controllable wavefront offsetting element to offset selected wavefront aberration components of the wavefront in order to measure one or more remaining aberration components of the portion of wavefront, to execute the program to assign one or more remaining wavefront aberration components to one or more corresponding variables, to receive a user-selected algorithm that processes one or more of the variables to assess or alter the one or more variables to provide a resultant value and to output the resultant value.
9. The apparatus of claim 8 further comprising:
a display device; and
with the controller further configured to display the one or more variables and assigned data values.
