Polymethyl Methacrylate (PMMA) Intraocular Lens
Polymethyl Methacrylate(PMMA) was the first material used for IOLs. It is a rigid, non-foldable, hydrophobic (water content <1%) material. The refractive index is1.49, and the usual optic diameter is 5–7 mm. PMMA offers outstanding stability and optical quality for a predictable outcome and maximum performance.

Polymethyl Methacrylate (PMMA) Intraocular Lens Design features:
1- The IOL produced by our company is made of PMMA, allowing the good flexibility of the loops,which can be bent to the optical part of the IOL, making the IOL implanted easily inside the capsular bag.
2- The 10°angle of the haptic allows the lens to have a complete contact with the posterior side of the lens capsule.
3- The thin edge of the IOL reduces the edge glare in a large degree.
4- The haptic are designed to maintain stability of lens implant in the eye, which keeps the IOL centered in the optical field.
5- The IOL produced by our company can filter the ultraviolet rays effectively, and the rate of the visible light is greater than 90%.
