Method of using small diameter intracorneal inlays to treat visual impairment
First Claim
1. A method for treating presbyopia using an intracorneal inlay, comprising:
- altering the shape of the anterior surface of a cornea to correct near vision by implanting the inlay in the cornea, wherein the inlay has a diameter of approximately 2.5 mm or less, and distance vision is provided by a region of the cornea peripheral to an area of the anterior surface affected by the inlay.

Abstract
Provided herein are small diameter inlays for correcting vision impairments by altering the shape of the anterior corneal surface. In an embodiment, inlays having diameters smaller than the pupil are provided for correcting presbyopia. To provide near vision, an inlay is implanted centrally in the cornea to induce an “effective” zone on the anterior corneal surface, within which diopter power is increased. Distance vision is provided by a region of the cornea peripheral to the “effect” zone. In another embodiment, small diameter inlays are provided that induce effective optical zones on the anterior corneal surface that are much larger in diameter than the inlays. The increase in the effective optical zone, due at least in part to a draping effect, allows an inlay to produce a much larger clinical effect on a patient'"'"'s vision than the diameter of the inlay.

16. A method for correcting vision impairment, comprising:
implanting an inlay having a diameter less than 4 mm in a cornea of an eye, wherein the inlay produces an effective optical zone on the anterior surface of the cornea greater than the diameter of the inlay, wherein the diameter of the inlay is less than the diameter of a dilated or undilated pupil of the eye, and wherein the effective optical zone is smaller than the pupil of the eye. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34)

35. A method for providing near and distance vision in an eye using an intracorneal inlay, comprising:
-
altering the shape of a region of the anterior surface of a cornea of the eye to provide near vision by implanting an inlay in the cornea, wherein the inlay has a diameter less than 4 mm and less than the diameter of a dilated or undilated pupil of the eye, wherein a region of the anterior surface of the cornea affected by the inlay is larger than the diameter of the inlay; and providing distance vision in a region of the cornea peripheral to the region of the anterior surface of the cornea affected by the inlay. - View Dependent Claims (36, 37, 38)
