Small diameter corneal inlay methods
Methods of manufacturing a corneal implant that include creating an implant body that has a meniscus shape, a diameter of approximately 2.5 mm or less, and an index of refraction of 1.376. The implant body can further have a central thickness and an outer edge thickness.
1. A method of manufacturing a corneal implant and implanting the corneal implant in an eye, 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;
creating a flap in a cornea to expose a corneal bed;
positioning the implant body on the corneal bed; and
repositioning the flap over the implant body,
wherein repositioning the flap over the implant body causes a change in an anterior surface of the cornea due to the implant body, the anterior surface after repositioning the flap 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 manufacturing step further comprises manufacturing the implant body to have a central thickness of about 32 microns, and an outer edge thickness of about 12 microns.
