A propeller having blades designed to achieve maximum thrust at lower static velocities in both forward and reverse pitch modes is disclosed. Each blade has a generous leading edge radius leading to an upper surface having positive camber and a lower surface having positive camber adjacent the leading edge and negative camber adjacent the trailing edge. Each blade also has a high thickness-to-chord ratio and lower span-to-chord ratio or aspect ratio. This thicker blade profile and aft loading leads to a more uniform pressure distribution and laminar airflow across the blade surface resulting in a higher coefficient of lift, increased blade life and reliability, and lower noise levels.

An intraocular lens four point contact haptics with an asymmetrical cross section. The ends of each of the haptics are contiguously juxtaposed and inserted in a common bore in the periphery of the optic. The legs of each of the haptics spiral outwardly in juxtaposed relationship, separate and extend away from each other to form eye contacting heel and toe portions residing on opposing sides of the inferior-superior axis of the lens. When two such haptics are employed, a wide haptic compression range can be achieved with little differential in compression force.
