Small Diameter Inlays
Small diameter corneal inlays adapted to change the corneal surface curvature to provide central near vision and peripheral distance vision.
1 . A corneal inlay, comprising:
an inlay body having a diameter between about 1 mm and about 3 mm, wherein the body has an index of refraction that is substantially the same as a cornea.
2 . The inlay of claim 1 wherein the diameter of the inlay body is about 2 mm.
