ABSTRACT:
The intraocular lens may have closed loop haptics or open loop haptics. Each closed loop haptic has two coil portions and each open loop haptic has one coil portion. The purpose of the coil portions is to provide the desired flexibility and to provide for geometric stable haptic flexion upon the application of compression force to the peripheral portions of the haptics towards the lens body.
