"Currency will also negatively impact our expectations for next year," William Carpenter, the company's chairman and chief executive, said in a statement.

Bausch & Lomb revised downward its earnings projections for next year, to between $2.70 and $2.75 cents a share compared with a consensus estimate of $2.86 per share.

At the same time, the company said it was slashing 450 non-manufacturing jobs over the next several months, part of a restructuring plan aimed at cutting costs.

The announcement of the job cuts and earnings warnings came in a press release announcing the company's third-quarter earnings, which matched Wall Street estimates of 70 cents a share.

Bausch & Lomb closed Thursday regular trading down $1.56, or 4%, at $37.50.
