July 27 (Reuters) - Laser vision-correction service provider LCA-Vision Inc LCAV.O posted a narrower-than-expected quarterly loss, helped by closure of under-performing vision centers.
For the second quarter, the company reported a net loss of $4.3 million, or 23 cents a share, compared with a loss of $6.9 million, or 37 cents, a year ago.
Revenue fell 17 percent to $26.3 million.
Analysts on average expected the company to post a loss of 29 cents a share, excluding items, on revenue of $26.1 million, according to Thomson Reuters I/B/E/S.
Direct costs of services fell 26 pct, while marketing and advertising expenses fell 34 percent during the quarter.
"We reduced our operating loss as a result of actions to conserve cash and align expenses with anticipated demand," LCA-Vision Chief Financial Officer Michael Celebrezze said in a statement.
LCA-Vision operates LasikPlus vision centers that offer eye-sight correction services in the United States.
Shares of the company closed at $5.23 Monday on Nasdaq. (Reporting by Shailesh Kuber in Bangalore; Editing by Prem Udayabhanu)
