A variety of new "special" intraocular lens models to optimize the visual performance after cataract surgery have been introduced. The majority of these new intraocular lens designs require a good centration within the capsular bag and/or capsular elasticity. Today, the main post-operative complications after cataract surgery still arise from retained lens epithelial cells within the capsular bag, resulting mainly in anterior and posterior capsule opacification. Some special intraocular lenses are not designed to be effective against proliferating lens epithelial cells. Although lens epithelial cells can never be completely removed from the capsular bag, surgical quality is a major factor for success or failure of these intraocular lens designs.
为优化白内障手术后的视觉性能，已推出多种新型“特殊”人工晶状体模型。这些新型人工晶状体设计大多需要在囊袋内良好居中及/或具备囊膜弹性。如今，白内障手术后的主要术后并发症仍源于囊袋内残留的晶状体上皮细胞，主要导致前囊膜和后囊膜混浊。一些特殊人工晶状体并非设计用于有效对抗增殖的晶状体上皮细胞。尽管晶状体上皮细胞永远无法从囊袋中完全清除，但手术质量是这些人工晶状体设计成败的主要因素。
