Description

technical field

[0001] The present invention relates to intraocular lenses and, in particular, to replaceable multi-component multifunctional intraocular lens systems. Background technique

[0002] After more than half a century of development, intraocular lens (IOL) implantation has become a routine method for the treatment of lens diseases such as cataract. The original lens is removed by means of extracapsular extraction or phacoemulsification, and then an IOL that can replace the refractive function of the original lens is implanted, so that the patient regains vision. With the continuous improvement of cataract surgery technology and IOL manufacturing technology, the treatment effect of IOL implantation has also put forward higher and higher requirements, from the initial limited to regaining vision, it has gradually developed into the hope of obtaining a more comprehensive and better treatment. vision, even restoring the level of vision seen in healthy young adults. ...
