Results:
Of the 17 eyes considered for ACAP only 7 were treated due to issues of corneal tissue ablation depth or such irregularity that the topographer could not generate a scan. Treatment was either LASIK or surface based. Spherical error varied from +6.00DS to -5.3DS. Astigmatic corrections varied between -0.25DC and -4.25DC in magnitude. The magnitude in spherical change varied from 0.25DS to 7.5 DS. While the cylindrical power change varied between 0 and 0.75 DC. One person lost a line of best corrected vision, one had no change and the rest had an improvement in best corrected visual acuity.
