Abstract

A method for reshaping a cornea to meet the refractive needs of a patient is provided. The method includes: providing apparatus suitable for conducting keratomileusis in situ, the apparatus including a keratome means to cut across and remove a section of the cornea, and positioning means to maintain shaping means in register with respect to the cornea, the shaping means (8) having a lower surface which can be brought into contact with the cornea (2), and engaged to downwardly depress the exposed surface of the cornea into a substantially flat configuration across a predefined optical zone; engaging the lower surface (8) with the surface of the cornea, depressing the cornea and then causing the keratome to move across the cornea removing a predetermined section of the cornea thereby creating a revised exposed surface and retaining the section for later reattachment.
