Brief summary
Pilot study to evaluate usability of Mesotest II for assessment of night driving capacity of pseudo-phakic patients implanted with aspheric monofocal posterior chamber IOL \*AT.Smart 46LC. Target Criterion: Measurement of contrast sensitivity and sensitivity to light under mesopic conditions (Mesotest II, Oculus).
Interventions
DEVICE*AT.Smart 46LC
Primary implantation of \*AT.Smart 46 LC into the eye's capsular bag for the visual correction of aphakia in persons in whom the cataractous lens has been removed by phacoemulsification extracapsular cataract extraction. The IOL is intended to be placed only in an intact capsular bag. When implanted, the \*AT.Smart 46LC replaces the natural lens of the eye and functions as a refracting medium in the correction of aphakia.
