DISPLAYING THE MEASUREMENT RESULT
(6) Fourth-order display
Fourth-order aberrations of Zernike coefficient are displayed (Tet-
rafoil, 2nd Astig. and Spherical aberration).
(7) Ocular display
Aberration of the whole eyeball obtained from the Hartmann image is
displayed in 3rd and 4th-order.
(8) Corneal display
Aberration of the cornea surface obtained from the Placido image is
displayed in 3rd and 4th-order.
(9) Internal display
Internal aberration (aberration of whole eyeball minus aberration of
cornea) is displayed.
(10) Aberration RMS display
RMS values (exception: diopter for astigmatism) and angles are dis-
played in analysis diameters (4mm and 6mm). For the direction of
RMS of each order, see "DESCRIPTION ABOUT RMS DISPLAY OF
CORNEAL ABERRATION" on page 89).
