Intraocular lens that matches an image surface to a retinal shape, and method of designing same

摘要

An intraocular lens (IOL), system, and method having a base lens and a complementary lens selected to form a curved image surface matching a retina surface when placed in an eye's line of sight.

主权项

1. A method of matching an image surface to a retina surface, comprising:
receiving a measurement of at least a shape of a retina of a subject eye; determining a lens power that would focus light passing through the cornea and the pupil of the subject eye onto the retina surface; determining a shape of an image surface that would be produced by the eye with an IOL having the lens power; comparing the image surface shape to the shape of the retina surface; selecting a base lens power, including:
in the case the image surface is flatter than the retina surface, selecting a base lens power greater than the lens power;in the case the image surface is less flat than the retina surface, selecting a base lens power less than the lens power; calculating a complimentary lens power equal to the lens power minus the selected base lens power; and providing for insertion in the subject eye's line of sight a base lens having the base lens power and a complementary lens having the complementary lens power.
