Small diameter corneal inlays
Methods of manufacturing and implanting corneal inlays, such as small diameter corneal inlays, are provided. The methods include manufacturing an implant body to have a meniscus shape with a small diameter and an index of refraction, and implanting the implant body in a corneal bed of a cornea. The inlays cause a change in an anterior surface of the cornea after implantation due to the implant body.
1. A method of manufacturing a corneal implant and implanting the corneal implant in an eye, the method comprising:
manufacturing an implant body to have a meniscus shape, a diameter of approximately 2.5 mm or less, and an index of refraction of 1.376; and
implanting the implant body in a corneal bed of a cornea;
wherein implantation of the implant body into the corneal bed causes a change in an anterior surface of the cornea due to the implant body, the change in the anterior surface of the cornea including a central region of increased curvature for near vision and an intermediate region for intermediate vision, while retaining distance vision in a region peripheral to the intermediate region.
2. The method of claim 1 , wherein the implant body is implanted below a flap formed in the cornea.
3. The method of claim 2 , wherein the flap is repositioned over the implant body after implantation of the implant body in the corneal bed.
