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.

Small diameter corneal inlays

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.

Small diameter corneal inlay methods

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.
