Arms Assigned Interventions
*AT.Smart 46LC
The *AT.Smart 46LC is indicated for primary implantation 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.
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.
