Abstract
Purpose:
To characterize corneal morphology and corneal optic quality in a population of normal pre-adolescents, adolescents, and young adults
Methods:
554 eyes of 277 students (ages 11-20). Corneal Syrius Topographer (CSO) using for measured corneal parameters: corneal asphericity, Sim-K, corneal meridians (at 3,5,7 mm), corneal pachimetry, corneal asymmetry, corneal aberrations at different pupil diameters
Results:
Minimun corenal thickness was 547,95 microns and central corneal thickness was 551,27 microns; LSA 5 mm front was 1.06 and LSA 5 mm total was 0,91; Cyl 5 mm front was -0,83 D and Cyl 5 mm total was -0.59 D; for coma front 0,167 microns and for coma total 0,15 microns; for Slf anterior -0.02 D and for Slb posterior 0.01 D; for Avg 3 mm corneal meridians 7.78 mm.
Conclusions:
Most of the evaluated corneas shows normal parameters; the separated analysis of right eyes and left eyes has confirmed the presence of the enantiomorphism; corneal topography allows early diagnosis of keratoconus.
