NIDEK Hyperopia Clinical Study Update & Future FDA Studies


FREMONT, Calif., May 4, 2004 (PRIMEZONE) -- NIDEK, Inc. announced today that it has completed and submitted 3-month clinical data for its new hyperopia study to the FDA. This marks an important milestone in the study process, as additional treatment eyes will be initiated in the study protocol effective immediately. NIDEK also received approval from the FDA to expand the clinical study to 300 eyes under the current treatment protocol. The expansion will include 150 eyes each for spherical hyperopia and hyperopic astigmatism. NIDEK has worked closely with the FDA on the design, initiation and evaluation of the clinical study.

"We are excited and very pleased with these initial results of the new hyperopia software for the US EC-5000 platform. The study expansion approval to 300 eyes marks an important milestone for the hyperopia trial. We look forward to evaluating the 6-month follow-up data in short order, as this initial data sample is an excellent step in getting the new hyperopia approved for the US Market", commented George Waring, III, MD, Medical Monitor for the NIDEK US Hyperopia Study and Chairman of NIDEK's Medical Advisory Group.

Below are the 3-Month data generated with 46 eyes treated with the new hyperopia algorithm. A total of 70 eyes have been completed as part of this clinical trial.
