Ocular inlay with locator
First Claim
1. An implantable ocular device comprising:
- a therapeutic inlay configured to be implanted at a selected region of a patient'"'"'s eye at least partially within a pupil region of the eye to provide therapy for at least one vision deficiency; and
a locator structure configured to be implanted within the eye and to extend at least partially outside of the pupil region of the eye to be accessible post-implant from outside the pupil region.

Abstract
A therapeutic ocular inlay for treatment of one or more vision defects including a locator structure or depth marker to facilitate location of the inlay post-implant. The locator structure or marker extends at least partially outside a pupil region. The depth or layer at which the inlay is implanted can be determined by locating the depth marker without requiring incisions with the pupil region. The locator structure can be substantially invisible under casual observation, however can be provided with enhanced optical contrast characteristics under selected viewing conditions. The locator is thus unobtrusive, however can be readily located in a clinical setting, for example with artificial UV illumination. The locator can be connected to, e.g., integrally formed with, the inlay or may be a separate component provided in combination with the inlay.

11. 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. - View Dependent Claims (12, 13, 14, 15)

16. 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. - View Dependent Claims (17, 18, 19, 20, 21)
