Abstract: Provided herein are systems and methods for additive manufacture of a customized ocular contact lens for a subject in a fast and convenient manner. In various aspects disclosed herein, methods disclosed herein provide for the imaging of the outer surface of a subject's cornea, designing a customized ocular contact lens based on the data from the imaging of the cornea, including determining anterior and posterior surfaces of the ocular contact lens, manufacturing the ocular contact lens using additive manufacturing, verifying the fit of the customized ocular contact lens on the subject's cornea, and verifying the optical power of the customized ocular contact lens. These features allow for the fast and convenient production of an ocular contact lens customized to a subject's cornea and manufactured to a specified optical power.
