Basically, what we want as eye care practitioners is to align the multifocal lens over the patient's line of sight--and not over the geometric centre of the cornea or the pupillary axis.
This sounds good, but the negative part of a positive angle kappa is that the visual axis is nasal to the pupillary axis.
5%), and among them, two persons had grade IV pterygium with pupillary axis
An analysis of 132 images indicated that many people wear the device near or overlapping their pupillary axis
(a line perpendicular to the surface of the cornea, passing through the center of the pupil), which may induce scotomas and interfere with daily function.
Average eye measures about 24 mm about pupillary axis and 23 mm in diameter .
Thus we assume that beam will propagate through all tissues along the eye pupillary axis resulting in absorption of laser energy according to absorption coefficient values of those same tissues.
Steady rise of the temperature along the eye pupillary axis can be seen on Figure 6 for three different values of ambient temperature.
