Efforts devoted to the production of accommodative lens implants may be premature as there is conflicting information about the functional performance of the aged ciliary muscle which may determine their performance. Additional doubts exist on the performance of the ageing lenticular capsule in connection with some types of implant. Not only do these matters need resolving, but the change in the optical power of the eye needs also to be large enough for reading glasses to become unnecessary. However, not all these strictures apply to the development of accommodative lens implants for children who may be aphakic following operations, e.g. for congenital cataracts.
致力于生产可调节人工晶状体的努力可能为时过早，因为关于老年睫状肌的功能表现存在相互矛盾的信息，而这可能决定人工晶状体的性能。对于某些类型的人工晶状体，老化的晶状体囊膜的性能也存在更多疑问。这些问题不仅需要解决，而且眼睛屈光力的变化还需要足够大，以使老花镜变得不再必要。然而，并非所有这些限制都适用于为儿童开发的可调节人工晶状体，例如那些因先天性白内障等手术而可能无晶状体的儿童。
