“…Ocorrem também alterações nas propriedades bioquímicas no núcleo do cristalino provocando esclerose e aumento de sua convexidade sagital (Adler-Gringberg, 1987;Cook et al, 1994;Gil del Rio, 1981).…”

“…Others reported negative corneal spherical aberration in the elderly (16) . Studies show negative spherical aberration in children, values near zero at about 30 year-old, and positive values after this age (17)(18) . This study, spherical aberration values were zero in young adults (15-24 year-old).…”

20/25, emmetropia or spherical equivalent < 3.50 SD, refractive astigmatism < 1.75 CD on cycloplegic refraction, normal ophthalmologic exam and no previous ocular surgeries. This protocol was approved by Federal University of São Paulo Institutional Review Board. Total optical aberrations were measured by H-S sensor LadarWave® Custom Cornea Wavefront System (Alcon Laboratories Inc, Orlando, FLA, USA) and were statistically analysed. Corneal aberrations were calculated using CT-View software Version 6.89 (Sarver and Associates, Celebration, FL, USA). Lens aberrations were calculated by subtraction. RESULTS: High-order (0.32 e 0.48 µm) and ocular spherical aberrations (0.02 e 0.26 µm) increased respectively in child and middle age groups. High order (0.27 µm) and corneal spherical aberrations (0.05 µm) did not show changes with age. Lens showed a statistically significant spherical aberration increase (from -0.02 to 0.22 µm). Vertical (from 0.10 to -0.07 µm) and horizontal coma (from 0.01 to -0.12 µm) presented progressively negative values with aging. CONCLUSION: High-order and spherical aberrations increased with age due to lens contribution. The cornea did not affect significantly changes observed on ocular aberrations.]]>
