My wife who has had to wear ahrd contacts from 16-60 had her 'eyes'replaced last year by a Prof of Optical Surgury at Moorfields. In her case the front of the lenses was delaminating sue to hard contacts use and had incipient cataract in one eye.
In practice the surgeon replaces both natural lenses with artificial toric lenses -toric lenses allow focussing at different lengths in the same way toric antenna can receive many different frequencies simultaneously.
Made an incredible difference from virtually legally blind without lenses to somethinga bit below 20 20. but as Isay she was startiing froma very bad baseline.
Prof also made the point that yes do not work as most people think and that there is a great deal of 'signal processing ' done in the brain to interpret what the eye receives and not all of this is wholly understood but stated earlier the effects are that the brain can correct the images you 'see' by interpreting the data it receives from the eyes . In suitable terms for this site eyes do not work like a basic radar system but like one with complex signal processors that give an improved 'picture'
This si still fairly new treatment in Uk so you may need to consider that but while I do not know the legalities as regards licences it is remarkable treatment that can produce spectacular results-life changing in wifeys case
