Hybrid intrastromal corneal ring |
| abstract |
This invention is a hybrid intrastromal corneal ring (50) ("ICR") comprising at least one outer layer of a physiologically compatible polymer having a low modulus of elasticity, which polymer may be hydratable and may be hydrophilic. The inner portion of the ICR may be hollow or may contain one or more physiologically compatible polymers. |
