A method of providing vision therapy comprising;

• implanting a first therapeutic inlay in a patient's eye at a selected level, the first inlay having a therapy region configured to provide therapy for at least one vision deficiency;
• and
• implanting a first locator structure at the selected level such that the selected level can be identified at a later time by accessing at least a portion of the first locator structure at a location of the patient's eye outside of the therapy region.

An inlay for implantation in a cornea of a patient between a first corneal layer and a second corneal layer, the cornea having a pupil region, the inlay comprising:

• a mask body having an outer periphery that substantially surrounds a transmissive central portion, the mask body comprising an anterior surface configured to reside adjacent the first corneal layer and a posterior surface configured to reside adjacent the second corneal layer, the mask body configured such that at least the transmissive central portion can be located in the pupil region of the cornea when the inlay is applied;
• and
• a depth marker configured to be positioned between the first and second corneal layers outside the pupil region, the depth marker configured to indicate the location of the mask body.
