INTEGRAL GUIDANCE System Dimensions
You can toggle the INTEGRAL GUIDANCE System dimensions on/off by pressing the button at
the bottom left of the Surface Mapping Review Screen. The INTEGRAL GUIDANCE System
dimensions display the distance between the color-coded surface maps. As the surface maps are
moved, either by INTEGRAL GUIDANCE System imaging or the user, the numeric value of the
distance between the surface maps is displayed and updated.
Figure 3.94 Location of INTEGRAL GUIDANCE System Dimensions
The following measurements are taken along a vector orthogonal to the tilt of the lens:
• CCT (central cornea thickness)—distance between anterior and posterior cornea
• AD (aqueous depth)—distance between posterior cornea and anterior lens
• ACD (anterior chamber depth)—distance between anterior cornea and anterior lens
• LMP (lens meridian position)—distance from anterior cornea to lens equator (i.e.,
intersection of lens anterior and lens posterior surface maps)
• LT (lens thickness)—distance from lens anterior to lens posterior
• PD (pupil diameter)—pupil diameter including minor and major axis
• WTW (white to white)—limbus diameter including minor and major axis
