Biometric analysis of anterior segments of the eye with Scheimpflug Camera according to the type of cataract

ABSTRACT

We measured the lens thickness and anterior chamber depth on 214 eyes (162 cataract eyes, 52 normal control eyes) using the EAS-1000 Scheimpflug camera. And the results was compared with measurement of A-scan ultrasonography in 49 cataract eyes. The thickness of cataract lens, especially in anterior subcapsular opacities in over 61 years old was significantly thin rather than control lens (p0.05). Lens thickness was increased with age by an annual rate of 0.0l5mm in monnal eyes (panterior chamber depth was found to be 5% shallower. We confirmed that thickening rates of lens is decreased in cataract and there is differences between the measurement of Scheimpflug camera and that of A-scan ultrasonography.
