[K1] : Radius of corneal curvature of minor meridian [mm] or corneal
refractive power (D)
[K2] : Radius of corneal curvature of major meridian [mm] or corneal
refractive power (D)
[KAI] : (Kerato-asymmetry Index) Index showing asymmetry of corneal
shape obtained by keratometer measurement. An index is
calculated for an ellipse obtained by calculation of keratometer
measurement according to misalignment between the center of the
ellipse and alignment position (almost the center of the optical
axis). As this index gets larger, the ellipse deviates from the ring
projected onto the eye during keratometer measurement and it is
more probable to be irregular astigmatism of keratoconus etc.
[KI] : Cornea equivalent refractive index (Keratometric Index)
[KRI] : (Kerato-regularity Index) Index showing regularity (irregularity) of
corneal shape obtained by keratometer measurement. An index is
calculated from misalignment between an ellipse obtained by
calculation of keratometer measurement and a ring projected onto
an eye subject to keratometer measurement. As this index
becomes larger, the projected ring is not a proper ellipse and it is
more probable to be higher order irregularity of keratoconous which
cannot be corrected with optical glass lens.
[M.A] : Manual Alignment / Auto Measurement
[M.M] : Manual Alignment / Manual Measurement
[OKULIX] : IOL power calculation software that uses the ray tracing
method.IOL power calculation software that uses the ray tracing
method. We install this software in OA-2000 as an import agent.
[OPT] : Optical axial length measurement
[OptLength] : Optical distance from the tear to the retinal pigment epithelium.
[Pachy] : Corneal thickness measurement
[Phakic] : Phakic eye
[PL] : Abbreviation of POST LASIK
[PMMA] : Eye with a PMMA lens inserted
[Post] : After refractive power correction surgery.
[Pre] : Before refractive power correction surgery.
[Pupil] : Shows the pupil diameter in [DIA] mode for corneal diameter
measurement/pupil diameter measurement.
[SNR] : Signal to noise ratio.
A larger value represents large interference signal, meaning higher
quality signals can be obtained.
