Pro-Laser reports a net loss of $262,000 for the 1st quarter ended March 31, as compared to $14,000 in the year-ago period, but margins improved. The operating income rose to $446,000 from $48,000. Sales revenues surged to $13,579,000 from $709,000, largely due to the acquisition of Weco and Rodenstock Instrumente. On a pro forma basis, sales rose by 13 percent, but they should grow faster this year, judging from an order backlog of $16.8 million at the end of the period. Fielmann, Apollo Optik, Vision Express and other major chains placed large orders for edging machines and other Pro-Laser equipment sofar this year. The group's cost structure is expected to improve in the next few months. Meanwhile, Pro-Laser has obtained a US patent for a process to change the curvature of the cornea in its Rodenstock refractive laser, which is now insalled in 22 European eye care clinics.
