Three major intraocular lens brands in the world
Intraocular lens or pseudolens, also known as intraocular lens. It is usually used to replace the self-turbid lens after cataract surgery. At present, polymethyl methacrylate (PMMA) has been widely used in clinic as a good intraocular lens material. Although both silica gel and glass have applications, they are not common. In recent years, some new intraocular lens materials have been introduced, such as hydrogel, polycarbonate and polysiloxane. Folding intraocular lens can be made of silica gel and hydrogel, so it can be implanted into the eye through a small incision of 3.5 mm
