Abstract: | Intraocular lens implantation surgery is the only approach for cataract treatment at present. Apart from removing the cloudy lens, correction of refractive errors becomes the second main function of intraocular lenses. This paper systematically summarizes the intraocular lenses in terms of its material, design, manufacturing and evaluation. The next generation of intraocular lenses with customized freeform surfaces is highlighted from the lens design viewpoint. The status of processing and measurement methods is presented for both current intraocular lenses and future freeform lenses. Finally, the research perspectives are outlined. |
