What is the most common type of artificial lens used in cataract surgery?

The most common type of artificial lens used in cataract surgery is the plastic intraocular lens (IOL). These lenses are specifically designed to replace the natural lens of the eye that has been removed during cataract surgery. The plastic materials used in IOLs, such as acrylic or polymethyl methacrylate (PMMA), offer several advantages, including excellent optical clarity, biocompatibility, and durability.

Plastic IOLs are lightweight and provide good vision outcomes, which makes them a popular choice among ophthalmic surgeons. They come in various designs, including monofocal (for a single distance), multifocal, and toric lenses for astigmatism correction, addressing a range of patient needs. The widespread use and proven effectiveness of plastic IOLs in restoring vision after cataract surgery contribute to their status as the most common type of artificial lens in this procedure.

Other types of lenses, such as silicone or hydrogel lenses, are not typically used in cataract surgery. Silicone lenses can be used in certain situations, but they are less common compared to plastic IOLs. Rigid gas-permeable lenses are primarily used for fitting conditions like irregular astigmatism or keratoconus rather than as intra
