Contact lens giant Bausch & Lomb is just full of surprises. Just one week after its announcement regarding the possible buyout by private equity firm Warburg Pincus for about $3.6 billion they now report interest from Advanced Medical Optics Inc suggesting a bidding war may be ahead.

While the company left the door open for further interest following the Warburg Pincus offer, the quick response from Advanced Medical Optics caught the industry by surprise. This is the same company which suffered from two product recalls in the past twelve months and still hasn’t recovered from the loss of their leading product Renu with Moistureloc solution.
