AL: Axial length; AL/TCRP: Axial length/total corneal refractive power ratio; F: Front (anterior corneal surface); Km: Mean keratometry; Astig: Astigmatism; WFA 4-mm zone: Wave front aberration in the 4-mm zone around the corneal apex; WFA Z40: Total corneal spherical aberrations (Z4,0) in the 6-mm zone around the corneal apex; WFA HO RMS: Root mean square of the total corneal high order aberrations calculated in the 4-mm zone around the corneal apex; B/F ratio: Mean radius of the posterior corneal surface/mean radius of the anterior corneal surface ratio; ACD: Anterior chamber depth; Cornea dia: Corneal diameter (horizontal); Pupil dia: Pupil diameter; Pachy apex: Corneal thickness at the apex; Pachy pupil: Corneal thickness at the pupil's center.
