Abstract
A contact lens with a sensor region are described. The contact allows for normal vision and a concentric ring around the vision area of the lens includes one or more sensors for detecting changes in the interocular pressure of the eye. The data may be scanned using a camera, or in some embodiments, the data may be transmitted using a micro antenna in the sensing region. The data may be analyzed using a software application on a cell phone or other computing device.
Claims16
A method for the production of a contact lens and sensor apparatus, the method comprising:
- forming a bottom membrane layer by coating a curved mold with a liquid elastomer;
- curing the bottom membrane layer;
- treating the bottom membrane layer with plasma to make an elastomeric surface hydrophilic and promote adhesion of a first UV curable or heat curable polymer;
- coating the bottom membrane layer with the first UV curable or heat curable polymer;
- imprinting at least one microfluidic layer on the first UV curable or heat curable polymer using an etched mold;
- making a top membrane layer by pouring elastomer on to a second curved mold;
- curing the top membrane layer;
- releasing the top membrane layer after curing;
- performing a plasma treatment on the inside of the top membrane layer;
- coating an inside of the top membrane layer with the first UV curable or heat curable polymer, and partially curing to solidify the first UV curable or heat curable polymer;
- placing the top membrane layer onto a pressurizing chamber;
- bonding the top and bottom membrane layers together to form a contact lens and sensor template;
- cutting the contact lens and sensor template to size, the cutting forming an abrupt edge on the contact lens;
- and applying a second UV curable or heat curable polymer to the abrupt edge of the contact lens to form an atraumatic edge.
