ABSTRACT:
The present invention provides a method for making an ophthalmic device. In particular, the present invention provides a method for production of a contact lens by means of stereolithography. A preferred stereolithography technique is based on polymerization and solidification of a contact lens forming liquid material by actinic irradiation one layer at a time. In addition, the present invention provides systems and methods for making a contact lens for a specific patient based on the prescription.
