This excerpt taken from the EYE 10-K filed Feb 24, 2009.
If health care providers or our customers do not continue to support our products, our revenue and profitability may decline.
We market our products to numerous health care providers, including eye care professionals, hospitals, ambulatory surgical centers, corporate optometry and LASIK chains and group purchasing organizations. We have developed and strive to maintain appropriate relationships with members of each of these groups who assist in product research and development and advise us on how to satisfy the full range of surgeon and patient needs. The failure by these various groups to support our existing products and any new products we may introduce to retain the support of these various groups could have a material adverse effect on our business, financial condition, results of operations and cash flows.
