Brief Summary:
The Lentechs Apioc-S and Apioc-A contact lenses are made in an FDA-approved contact lens material indicated for single-vision and astigmatism. The novel lens design has a lenticular portion which is thicker than the optical portion of the lens. When applied to the eye, it is oriented in a superior position. Unlike contact lenses currently on the market, this innovative design improves lens stability by preventing lens rotation, and may improve tear flow behind the lens.
