21. Fluorescein evaluation of the lens-to-cornea fitting relationship should be performed at both the fitting and all progress evaluation visits.

27. a. Palpebral Aperture Size(PAL) . Normal PAL values range between 9mm-10.5mm. In most lid-to-cornea relationships there is, at minimum, slight overlap of the lids over the limbus.
