PRESBYOPIA LENS WITH PUPIL SIZE CORRECTION BASED ON LEVEL OF REFRACTIVE ERROR

摘要

Ophthalmic lenses for the treatment of presbyopia may be improved to enhance the visual experience of the patient. By adjusting the optical design of presbyopic lenses to account for changes in pupil size due to the degree of myopia or hyperopia, an enhanced visual experience may be achieved independent of the level of ametropia.

主权项

1. A method for improving ophthalmic lenses for the treatment of presbyopia, the method comprising the steps of:
creating a base optical design with predetermined features for a lens for treating presbyopia; determining the power profile of the base optical design, Pnominal; and scaling the radial location of the predetermined features within the base optical design in proportion to the population average pupil size for the degree of ametropia of a target individual.
