Artificial lenses, or pseudo-lenses, are also called intraocular lenses. It is mostly used after cataract surgery to replace the removed cloudy crystals. At present, polymethylmethacrylic acid methyl ester (PMMA) as a better material for artificial crystal, has been widely used in clinical practice. Silicone gel and glass are used, but not yet common. In recent years, some new IOL materials have been introduced, such as hydrogel, polycarbonate, polysiloxane and so on. Silicone gel, hydrogel as a material can be made into a folded IOL, so that through a small incision of 3.5mm implanted in the eye.
Categorization of IOLs:
1. According to the location of placement: anterior chamber type, iris plane type, posterior chamber type.
2, according to the characteristics of whether it can be folded: hard crystal (can not be folded), soft crystal (can be folded).
3, according to the optical part and loop material is consistent or not: three body type, one body type.
4, according to the design shape of the loop: C-type, J-type, CJ-type and so on.
To learn more about IOLs, it is recommended to consult Beijing Meier Eye Run Vision Eye Hospital. With the further advancement of China's healthcare system reform, Meier Eye Group actively conforms to the national healthcare policy and development trend, gradually develops hierarchical healthcare, and always focuses on the innovation and development of service undertakings in terms of patients' choice of consultation, consultation process, etc., so as to provide high-quality and multi-level ophthalmology medical services for everyone, and also to enable the patients to enjoy the fruits of modern medical treatment.
