The ownership of the British laser surgery provider Ultralase has switched from 3i, the British investment fund, to a consortium of banks that include Royal Bank of Scotland and Barclays. The company's chief executive, Tony Veverka, told the Mail on Sunday that it was a ?debt for equity swap,? necessitated by a large debt incurred when 3i bought Ultralase. Payment of the debt was taking up most of the cash generated by the company.
