A lens (I,I',I") for implantation into the cornea (C) of the eye for providing correction for myopia and myopia with accompanying astigmatism wherein a corneal cap (Cp) section is removed and an implant bed is created to receive the intracorneal lens (I, I', I"). The intracorneal lens (I, I', I") is formed of a hydrogel type material or other material highly compatible with corneal physiology. In the range of lens powers of approximately -1.0 diopters to -30.0 diopters, the posterior surface (15) radius of curvature (PCCR) conforms to the receiving surface (S3) of the lamellar bed (LB) of the cornea (C) and the anterior surface (10) has the radius of curvature (ACCR) necessary to provide the desired lens power for achieving the desired change in the refractive power of the cornea (C). The lens (I, I', I") includes a peripheral transitional zone (20) to join the anterior surface (10) and posterior surface (15) to allow the lens (I, I', I") to be implanted onto the corneal bed and to allow for a smooth overlay of the replaced corneal cap (Cp) section. |
