A photodocumented study on lens thickness and densitometric value according to the type of cataract.

Abstract:

:Photodocumented measurements of the lens thickness using an EAS-1000 Scheimpflug camera were performed in 261 cataract eyes (162 pure type) compared with 52 control eyes. The lens thickness in normal eyes usually increased with age by 0.015 mm annually. The cataractous lens, especially in the anterior subcapsular type combined with the superficial cortical and posterior subcapsular types of opacity, showed statistically significant lens thinning. The photodocumented values of lens thickness were higher in 7.9%, and those of the anterior chamber depth were lower in 5% compared with A scan ultrasonographic measurements.
