Corneal Higher-Order Aberrations in Eyes With Corneal Scar After Traumatic Perforation.

摘要: OBJECTIVES To evaluate corneal higher-order aberrations (HOAs) in eyes with scar after traumatic perforation and their correlation visual acuity. METHODS This retrospective consecutive case study included 40 of patients (mean age, 39.2±21.6 years), treated for at Tokyo Dental College, 18 normal control eyes. Higher-order anterior posterior surfaces total cornea were analyzed by swept-source optical coherence tomography. Correlations between HOAs acuity analyzed. RESULTS within 4-mm diameter significantly larger (anterior surface, 0.51±0.54 μm; 0.20±0.14; cornea, 0.52±0.50) as compared to controls (0.10±0.02, 0.02±0.01, 0.09±0.02, respectively; all P<0.001). 6-mm 1.15±1.31; 0.31±0.23; 1.09±1.28) (0.21±0.06, 0.06±0.01, 0.19±0.06, The most common topography pattern observed was the minimal change (37.5%), followed asymmetric (30.0%). Visual correlated surface: R=0.646, P<0.001; R=0.400, P=0.033; cornea: R=0.614, CONCLUSIONS Corneal perforations not only induces opacity, but also increases HOAs, which indicates a direct effect on
