Classification of intraocular lens and its intraocular biocompatibility / 中国组织工程研究

ABSTRACT

OBJECTIVE: The sole effective measure for cataract is replaced the epinephelos lens with intraocular lens. So, in this paper, we summarize the research process of intraocular lens, which can provide a reference for further study. METHODS: Medline, China Journal Net, Wanfang Data, SpringerLink, and ScienceDirect database were computer retrieved from 1997 to 2009. RESULTS: A total of 25 papers were included. All the papers were explained intraocular lens from the aspect of current situation, complication following implantation, and develop tendency. According to hardness, intraocular lens can be divided into hard intraocular lens and soft intraocular lens. Acrylic intraocular lenses showed better biocompatibility than the silicone intraocular lenses. In addition, the common complication following implantation was dislocation of lens. Therefore, the trend of further research was injection type intraocular lens. CONCLUSION: The results demonstrated that as a foreign body, the body would react to the implanted intraocular lens, which is a normal reaction. Therefore, it is necessary to consider the biocompatibility, postoperative visual function recovery, regulatory ability, as well as photoprotection in the design of intraocular lens.
