GAMAGORI, Japan, June 4, 2001 - Nidek Co., Ltd., a worldwide manufacturer of ophthalmic and optical equipment, announced today that Health Canada has issued an amended Medical Device License for the Nidek EC-5000 Excimer Laser System. Nidek has received the amended license for the EC-5000 for the treatment of hyperopia with and without astigmatism using the LASIK procedure.

The Nidek EC-5000 is now approved by Health Canada to treat myopia (nearsightedness) and hyperopia (farsightedness) using the following procedures:

    LASIK for hyperopia:
    0 to +6.0 diopters (D) in terms of manifest refraction spherical equivalent (MRSE) with or without a refractive astigmatism up to +4D cylinder

    LASIK for myopia:
    -1.0 to -14.0D MRSE with or without astigmatism of 0 to -4D cylinder

    PRK for myopia:
    -0.75 to -13.0D in terms of spherical equivalent with 0.75D astigmatism

    PARK for myopia:
    -1.0 to -8.0D in terms of MRSE with astigmatism of -0.5 to -4.0D cylinder

"The EC-5000 platform is designed to expand and support different treatment parameters and options," commented Hideo Ozawa, President of Nidek Co., Ltd. "Without needing to purchase an entirely new system, the EC-5000 platform allows refractive surgeons to offer the treatments their patients require for better vision. "
