A multifunction therapeutic optical device for treating an eye comprising a central cornea, a mid-peripheral cornea and a sclera, the optical device comprising: a central optical zone having a posterior surface profile configured to impart an altered shape to the central cornea of the eye being treated; a peripheral optical zone having a posterior surface profile different to the posterior surface profile of the central optical zone and comprising posterior and anterior surfaces, wherein at least one of the posterior surface profiles of the central optical zone and the peripheral optical zone is configured to reshape the surface of the mid-peripheral cornea to provide an altered mid-peripheral corneal geometry; and a peripheral landing zone configured to contact a peripheral ocular surface; wherein the peripheral optical zone vaults the mid-peripheral cornea in at least one semi-meridian while the central optical zone is in contact with the cornea and the peripheral landing zone is in contact with the cornea and/or the sclera in the same semi-meridian; wherein the posterior surface profile of the peripheral optical zone is configured to provide a tear lens in at least the area between the peripheral optical zone and the reshaped mid-peripheral corneal surface; wherein the anterior surfaces of the peripheral optical zone are configured to provide the peripheral optical zone with a relative plus power refractive effect suitable, in combination with a refractive effect from the altered mid-peripheral corneal geometry and a refractive effect from the tear lens, to focus on-axis and/or off-axis light incident to the peripheral optical zone at a target focal point located at a position that is anterior to a peripheral retina of the eye, wherein the relative plus power refractive effect is relative to the refractive effect of the mid-peripheral cornea of the untreated eye on the same on-axis and/or off-axis light. a central optical zone having a posterior surface profile configured to impart an altered shape to the central cornea of the eye being treated; a peripheral optical zone having a posterior surface profile different to the posterior surface profile of the central optical zone and comprising posterior and anterior surfaces, wherein at least one of the posterior surface profiles of the central optical zone and the peripheral optical zone is configured to reshape the surface of the mid-peripheral cornea to provide an altered mid-peripheral corneal geometry; and a peripheral landing zone configured to contact a peripheral ocular surface; wherein the peripheral optical zone vaults the mid-peripheral cornea in at least one semi-meridian while the central optical zone is in contact with the cornea and the peripheral landing zone is in contact with the cornea and/or the sclera in the same semi-meridian; wherein the posterior surface profile of the peripheral optical zone is configured to provide a tear lens in at least the area between the peripheral optical zone and the reshaped mid-peripheral corneal surface; wherein the anterior surfaces of the peripheral optical zone are configured to provide the peripheral optical zone with a relative plus power refractive effect suitable, in combination with a refractive effect from the altered mid-peripheral corneal geometry and a refractive effect from the tear lens, to focus on-axis and/or off-axis light incident to the peripheral optical zone at a target focal point located at a position that is anterior to a peripheral retina of the eye, wherein the relative plus power refractive effect is relative to the refractive effect of the mid-peripheral cornea of the untreated eye on the same on-axis and/or off-axis light.
