Cataract surgery, do you know the difference between standard and multifunctional lenses??

Best Tip

Sorry Doc8, but I have to correct you on this one. Multifocal (not multifunctional) Intraocular Lenses (IOL) are big business these days. For instance, Alcon makes the Restor IOL that is designed to provide some accommodative restoration using multifocal binary optics. Other manufacturers also have multifocal IOLs.
Some IOLs have recently completed FDA testing that have stretching capabilities, banking on the retention of elasticity retained in the ciliary muscles, the muscles that control accommodation. Hence, standard IOLs are on the way out. Multifocal IOLs are the way to go if you want to restore more vision capability. The downside is that they can be trickier to insert and require more skilled ophthalmologists, hence cost to the consumer rises just like any new technology.

Others
In modern cataract surgery, the lens is slipped out of the capsule and a small lens substituted. Any multifunction would be in glasses afterwards. Only patient with astigmatism need glasses.
