[Cautious choice of new intraocular lenses in patients with cataract rehabilitation surgery in China].

We must choose new intraocular lenses (IOL) cautiously and strictly in patients with cataract rehabilitation surgery in China because of following reasons. Firstly, there are no differences in visual acuity between traditional poly-methylmethacrylate (PMMA) IOL implantation group and new IOL (multifocal IOL, aspherical IOL) implantation group. Secondarily, there are many factors which affect visual performance after cataract surgery. Thirdly, many patients with cataract can not afford new intraocular lenses .Fourthly, there are several faultiness and clinical problems in new intraocular lenses. Therefore, correct selection of IOL should be affordable PMMA IOL in cataract rehabilitation surgery in China.
