IOL Haptic Fiber

iFLEX^® PES

Polyethersulfone (PES) haptic monofilament provides capability for higher temperature fabrication and sterilization of multi-piece IOLs.

iFLEX^® PES haptics can be formed on conventional fixtures at appropriately high temperatures. Loops formed under these conditions have shown post steam sterilization stability. Typical conditions for steam sterilization are 121° C at 15 psi for 15 minutes. Dry heat sterilization typical conditions are 160° C for 120 minutes.

• iFLEX® PES monofilament is a blue, fused, bilayer structure.  The core colorant is phthalocyaninato (2-) copper and the outer layer is natural PES.  Hue, chroma, color value and transparency give iFLEX® the visual appearance of bilayer blue PMMA haptic monofilament.

• iFLEX® PES haptics may be attached to optic parts using conventional techniques.

Safety and effectiveness of IOL haptic parts and lens assemblies using iFLEX^® PES monofilament must be determined by the IOL manufacturer.
