Methods, devices, and systems establish an optical surface shape that mitigates or treats presbyopia in a particular patient. The combination of distance vision and near vision in a patient can be improved, often based on input patient parameters such as pupil size, residual accommodation, and power need. Iterative optimization may generate a customized corrective optical shape for the patient.

L'invention porte sur des procédés, des dispositifs et des systèmes permettant d'établir une forme de surface optique qui atténue ou traite la presbytie chez un patient donné. La combinaison de la vision à distance et la vision de près chez un patient peut ainsi être améliorée, souvent en prenant en compte les paramètres d'entrée du patient tels que la taille de la pupille, l'accommodation résiduelle et le besoin de puissance. L'optimisation itérative peut générer une forme optique correctrice personnalisée au patient.
