This book bridges the gap between the clinical practice and the engineering of lens design. It explores advances in refractive correction in ophthalmic optics, with a focus on current and future intraocular lenses, and presents challenges for lenses with premium features as extended depth of focus and integrated functions. The text innovatively presents the content of ophthalmic lens design in a multidisciplinary fashion, combining the knowledge and experience of collaborative work among physicists, ophthalmologists, and engineers. It sheds light on both clinical and technical aspects of the eye optics to enable readers from both the medical and the engineering backgrounds to effectively communicate their needs and solutions, and to collaborate. It is meant to serve as a reference for any professional in the ophthalmic sector, from the drawing boards to the final implantation inside the eye.
