ABBOTT PARK, Ill.—Abbott's (NYSE: ABT) acquisition of Advanced Medical Optics (NYSE: EYE) could be finalized as early as today, following completion of AMO's tender offer on Feb. 24.

Advanced Medical Optics said this week that about 99.3 percent of its outstanding notes—valued at $248.3 million—had been tendered during the offer.

The two firms' waiting period under the Hart-Scott-Rodino Antitrust Act expired on Feb. 5, leaving the way clear for the acquisition to close.

Once the acquisition is completed, Advanced Medical Optics will become a wholly owned subsidiary of Abbott.
