Objective To study comparativelyhighand normal curvature accompaniedwithmyopia.Methods 53 eyes of 29 caseshad high corneal curvature of 46.02~47.82 D and 60 eyes of 30 cases had that of 41.35~45.61 D with no keratoconus measured by topography.The corneal topography,the dioptre(D),corneal astigmism,central corneal thickness(CCT) and intraocular pressure(IOP) was analyzed statistically in two groups.Results There was significant difference between high group and normal group in CCT,IOP,maximummeridian(Simk1),the vertical meridian (Simk2)and the min meridian(Mink).There was no significant difference between high group and normal group in the dioptre(D),the difference between simk1 and simk2(△k),the surface regularity index(SRI) and surface asymmetry index(SAI).Conclusion The CCT and IOP with high curvature is less than the normal value. |
