Therapeutic device for pain management and vision
First Claim
1. A method of treating a cornea of an eye of a patient, the method comprising:
- placing a covering on the cornea, wherein,the cornea comprises an epithelium;
the covering, when applied to the cornea, is adhered to the cornea to reduce swelling of the cornea; and
the covering comprises;
an inner portion, wherein the inner portion comprises an inner rigidity, an inner thickness, and an inner durometer; and
an outer portion, wherein the outer portion comprises an outer rigidity;
wherein the inner rigidity is greater than the outer rigidity; and
wherein the inner durometer is within a range of Shore 20 A to Shore 70 A.

Abstract
A therapeutic lens for the treatment of an epithelial defect comprises a layer of therapeutic material disposed over the stroma and/or Bowman'"'"'s membrane to inhibit water flow from the tear liquid to the stroma and/or Bowman'"'"'s membrane, such that corneal deturgescence can be restored to decrease corneal swelling and light scattering. The layer may cover and protect nerve fibers to decrease pain. The layer may comprise an index of refraction to inhibit light scatter from an anterior surface of the stroma and/or Bowman'"'"'s membrane. The lens may comprise a curved anterior surface that provides functional vision for the patient when the epithelium regenerates. The layer of therapeutic material can be positioned on the eye in many ways, for example with a spray that is cured to adhere the layer to the exposed surface of the stroma and/or Bowman'"'"'s membrane.
