摘要:
A contact lens is provided. It is a rigid gas permeable, corneal-scleral progressive, multifocal, vision lens that covers the cornea and a portion of the sclera of an eye. It is particularly beneficial for use on patients who have undergone refractive surgery and/or on patients experiencing presbyopia. The lens is designed to have dual touch contact with an eye. One contact point is the central portion of the cornea and the other contact point is a portion of the sclera.
