Staar Directors Sued Over Loan: A San Dimas company filed suit in Los Angeles County Superior Court Wednesday to collect a $325,000 loan made to directors of Staar Surgical Co. while they battled the chairman for control of the small Monrovia company. Vision Technologies International Inc. lent the money to officers and directors of Staar in September and October of 1989 on the condition that it be repaid with interest once the five-member board had been legally reinstated, the suit said. The directors were reinstated by a Delaware court on Oct. 13, 1989, but the loan has yet to be repaid, the suit said. Staar Surgical officials could not be reached for comment.
