    Customized contact lenses reshape the surface of the eye so that light focuses properly on the retina. In the morning, you remove the contact lenses and you will be able to see clearly all day long.

    Are you a candidate?

    Ortho-K is appropriate for all ages and can effectively treat myopia (nearsightedness -1.00D to -5.00D) and astigmatism (up to -1.00D).  Candidacy depends on your corneal shape, tear secretion, rigidity of your cornea and health of your eye.
