Abstract
Described herein are eye implants that can include a pressure-responsive material that can be capable of changing color in response to pressure exerted on it. Also described here are methods of implanting and using the eye implants described herein to monitor intraocular pressure in a subject. The pressure-responsive material can be used to diagnose and monitor human or animal subjects.
Claims19
An intraocular implant comprising:
- a pressure-responsive material, the pressure-responsive material comprising chromogenic photonic crystals, wherein the chromogenic photonic crystals change conformation resulting in a change of color of the pressure-responsive material in response to an amount of pressure exerted on the shape-memory chromogenic photonic crystals and wherein the chromogenic photonic crystal comprise smart shape memory polymers (SMPs), the SMPs comprising polyester/polyether-based urethane acrylates blended with tripropylene glycol diacrylate, wherein the implant is an intraocular lens.
An intraocular implant comprising:
- a pressure-responsive material, the pressure-responsive material comprising chromogenic photonic crystals, wherein the chromogenic photonic crystals change conformation resulting in a change of color of the pressure-responsive material in response to an amount of pressure exerted on the shape-memory chromogenic photonic crystals and wherein the chromogenic photonic crystal comprise smart shape memory polymers (SMPs), the SMPs comprising polyester/polyether-based urethane acrylates blended with tripropylene glycol diacrylate, wherein the implant is a glaucoma drainage device.
An intraocular implant comprising:
- a pressure-responsive material, the pressure-responsive material comprising chromogenic photonic crystals, wherein the chromogenic photonic crystals change conformation resulting in a change of color of the pressure-responsive material in response to an amount of pressure exerted on the shape-memory chromogenic photonic crystals and wherein the chromogenic photonic crystal comprise smart shape memory polymers (SMPs), the SMPs comprising polyester/polyether-based urethane acrylates blended with tripropylene glycol diacrylate, wherein the implant comprises one or more layers of the pressure-responsive material embedded in all or part of a surface of the implant or component thereof.
An intraocular implant comprising:
- a pressure-responsive material, the pressure-responsive material comprising chromogenic photonic crystals, wherein the chromogenic photonic crystals change conformation resulting in a change of color of the pressure-responsive material in response to an amount of pressure exerted on the shape-memory chromogenic photonic crystals and wherein the chromogenic photonic crystal comprise smart shape memory polymers (SMPs), the SMPs comprising polyester/polyether-based urethane acrylates blended with tripropylene glycol diacrylate, wherein the implant comprises one or more layers of the pressure-responsive material coated on all or part of a surface of the implant or component thereof.
An intraocular implant comprising:
- a pressure-responsive material, the pressure-responsive material comprising chromogenic photonic crystals, wherein the chromogenic photonic crystals change conformation resulting in a change of color of the pressure-responsive material in response to an amount of pressure exerted on the shape-memory chromogenic photonic crystals and wherein the chromogenic photonic crystal comprise smart shape memory polymers (SMPs), the SMPs comprising polyester/polyether-based urethane acrylates blended with tripropylene glycol diacrylate, wherein the pressure-responsive material is integrated with a component of the implant.
An intraocular implant comprising:
- a pressure-responsive material, the pressure-responsive material comprising chromogenic photonic crystals, wherein the chromogenic photonic crystals change conformation resulting in a change of color of the pressure-responsive material in response to an amount of pressure exerted on the shape-memory chromogenic photonic crystals and wherein the chromogenic photonic crystal comprise smart shape memory polymers (SMPs), the SMPs comprising polyester/polyether-based urethane acrylates blended with tripropylene glycol diacrylate, wherein the pressure-responsive material comprises a hydrogel.
