CINCINNATI (AP) â¿¿ LCA-Vision Inc., which operates laser vision surgery centers, said Tuesday that 15 percent fewer Lasik procedures were performed in the second quarter compared with the same time last year when the company operated more sites. The economic downturn has hit the company hard, leading to sharp declines in procedure volume as high unemployment has meant fewer people have the funds for elective surgery. LCA-Vision has closed centers over the last year to save money. The Cincinnati company said a total of 15,266 procedures were performed in the second quarter across its 62 vision centers in 29 states. That's down from 17,864 procedures in the year-ago period, when it operated 71 vision centers. Procedures at locations open at least a year dropped 5 percent from 16,144 a year ago. The company will release its full second-quarter results on July 27.
