Abstract

In Reply.  —We wish to clarify and correct several misunderstandings of our article.Our conclusion that "age and decreased visual acuity account for little of this disability" was based on our findings detailed in the subsections entitled "Glare Tests," "Contrast Sensitivity Tests," and "PSC and Nuclear Opacity Subgroups." In these subsections we described the persistence of the effect of cataract, even after accounting for the effects of age and visual acuity on visual function.We shared Dr Marmor's concern that the glare disability and contrast sensitivity loss affecting cataract patients might be highly correlated with visual acuity loss. That is why we adjusted (but not "corrected") our contrast sensitivity and glare data for acuity differences by using multiple regression techniques, as indicated in the "Data Analysis" section. In other words, even after accounting for the effect of reduced visual acuity, glare and contrast deficits remained.Dr Marmor's statement that a
