Abstract

Reduced contrast sensitivity and an increase in glare sensitivity may be observed in patients with cataract and in pseudophakic persons. By means of Mesoptometer II we examined night driving ability according to the recommendations of the German Ophthalmological Society (DOG) in patients with cataract, monofocal or multifocal pseudophakia. METHODS: A total of 176 patients were included in the study: 85 patients (68.8 years) with a monofocal standard IOL, 50 patients (66.1 years) with a multifocal IOL type AMO Array SSM-26NB/SA-40NB and 41 patients with beginning cataract (66.4 years). The corrected visual acuity of all patients was at least 0.7. Contrast acuity was examined at a luminance setting of 0.32 cd/m2; glare sensitivity was measured at a luminance of 0.1 cd/m2 with additional glare source. RESULTS: Night driving ability (both criteria accomplished) was found in 41% of patients with binocular monofocal IOL and in 38% of patients with binocular multifocal IOL. CONCLUSION: Elderly pseudophakic patients and patients with beginning cataract cannot sufficiently fulfill the criteria for night driving ability because of contrast and glare sensitivity. It seems to be indispensable, for the parameters mentioned to be carefully examined and for patients to be informed that night driving ability may be impaired, even if visual acuity is sufficient.
