Abstract

Electroretinogram(ERG), widely used to diagnose and prognose the retinal dysfunctions, is known to be affected by the various testing conditions, such as the amount and color of the stimulating light, adaptation time and background light intensity. We have recorded the ERG in 39 cataract patients(50 eyes)without retinal abnormalities in order to evaluate the effect of intraocular lens(IOL)on the ERG and to compare clear-IOL inserted eye with colored-IOL inserted eye. The insulting effect of IOL material did not affect the results of the ERG. However the rod response in IOL inserted eye showed shortening in implicit time, which was probably due to the increase of inputting light by the removal of opaque lens. Additionally, there was no difference between the ERG of colored-IOL(yellow-tinted IOL)eyes and that of clear-IOL eyes. We found that ERG might be used in the IOL inserted eyes without modification of data values.
