What material is an artificial lens made of?

An artificial lens (also called an intraocular lens or IOL) is usually made of flexible, durable and biocompatible materials that can safely remain in the eye without rejection reactions or irritation. The most commonly used materials are:

? Acrylic (Hydrophobic or hydrophilic acrylic)

- The most commonly used material because of its high biocompatibility and optical clarity.

- Hydrophobic acrylic prevents tarnishing and stays clear longer.

- Hydrophilic acrylic is more flexible and easier to implant.

? Silicone

- Less commonly used, but has high flexibility and lightweight properties.

- Can sometimes give more reflections and glare than acrylic.

? PMMA (Polymethylmethacrylate)

- Hard and dimensionally stable material that used to be widely used.

- Nowadays mainly in special hard artificial lenses, for example in secondary implantation.

Modern multifocal or toric artificial lenses may contain a combination of these materials for optimal performance. Some lenses also have a blue light filter or UV protection built in.

Conclusion:

Choosing the right material depends on your eye health, desired correction and personal needs. At Focus Eye Clinic, we are happy to help you choose the artificial lens that is best for you.
