WebOct 1, 1998 · In this case, a 0.50D flatter-than-K base curve radius produced an alignment fitting relationship. However, as a result of the fairly large pupil diameter, lenses 0.5mm larger were ordered. To maintain the same alignment fluorescein pattern, the final base curve radii were flattened an additional 0.25D. CASE 2: High Corneal Astigmat Web[155], [156] Adding FA to probes 65 and 66 solutions, the Schiff base was formed and the PET effect was inhibited from –NH 2 with the FRET process turned on. For FA, the fluorescence emission at the green channel of the free fluorophore would be released, while the quenched fluorescence emission at the blue channel was observed.
