Abstract: This paper presents the theoretical and practical aspects regarding the design and manufacturing of the customized contact lenses based on a proposal for a customized contact lens with a non-circular shape. Are proposed an oval shape and an approximate trapezoid shape for which arises the idea to calculate a coverage percentage that allows a comparison between the contour shapes of the contact lenses with regard to the direct oxygen transmission degree to the cornea. Another approach regards the possible combinations of surfaces of the customized contact lens, the determination of the curvature radiuses or the equation of the surfaces, while attempting to follow the closest shape to the geometry of the cornea and also the minimization of the aberration of the optical transfer function. Is presented an oval shaped contact lens manufactured in a fast-cast type system during laboratory conditions.
