Intraocular lens and artificial iris
Quite an odd one this one ...
If you had an intraocular lens (an artificial lens inside the eye that replaces your natural one) and an artificial iris AND a DSAEK corneal graft (that's just the innermost layer) ... but could get 6/9 monocular with that eye and 6/6 binocular ...
Could you get a Class 1?
This is assuming the eye is stable some months after the operation, which was required because of trauma.
If not, what is the point of medical advances?
