Shares of

Escalon Medical


were among the best-performing health-related stocks Tuesday, rising 33.7% after the company posted third-quarter results and provided an update to its legal dispute with


( ILSE).

The medical device maker earned $743,558, or 12 cents a share, on sales of $7.2 million. The one analyst who was polled by Thomson First Call was looking for a loss of 4 cents a share on sales of $6.6 million. A year ago, the company earned $739,174, or 17 cents a share, on sales of $3.6 million. Most of the sales increase came from Escalon's acquisition of Drew Scientific Group, which it acquired in July 2004. Excluding Drew, the company would have earned $940,000, or 15 cents a share, on sales of $4.2 million.

Separately, Escalon said it filed a complaint against IntraLase for breach of contract and breach of fiduciary duty. The complaint alleges that IntraLase acted in bad faith under a license agreement for laser technology. Escalon is seeking declaratory relief, specified damages and specific performance for its rights under the license agreement -- including its right under the agreement to have independent accountants audit the books and records of IntraLase to verify and compute payments due Escalon Medical.

Earlier this month, according to Escalon, a California court entered a judgment -- in a separate case -- that IntraLase must pay Escalon royalties on revenue from maintenance contracts and one-year warranties. IntraLase, however, is not required to pay royalties on research grants, though IntraLase must give Escalon an accounting of third-party royalties. Shares of Escalon traded up $1.72 to $6.83. Shares of IntraLase traded down 1 cent to $17.50.
