title: [Diurnal vision and mesopic vision in patients with monofocal and diffractive bifocal implants. A prospective and comparative study].
abstract: In a prospective study we implanted 34 monofocal posterior chamber lenses and 34 diffractive bifocal posterior chamber lenses. The corrected distance acuity of both groups with comparable age showed no significant difference. To compare functional results of both groups under mesopic conditions we examined all patients with the Mesoptometer II. We determined the visual acuity under field luminance of 1.0 cd/m2 and contrast thresholds under field luminance of 0.1 cd/m2. The results-of patients with diffractive bifocal posterior chamber lenses were significantly reduced compared with patients with monofocal posterior chamber lenses.
