I had traumatic damage to my right eye in 1992 from a piece of metal. The piece was removed and damage repaired. Six days later I had an intraocular implant put in. 30 days later the sight in that eye was 20/40 and two months later it was 20/25 and has stayed like that. Despite a slightly damaged iris, I have no halos etc and the eyesight in the damaged eye is now better than the undamaged one. It took 4 months to get a restricted medical back and then after one year I was given full Class 1 medical with no restrictions other than an ophthalmologists report annually. After 21 years I still have a Class 1 medical and still fly for an airline.
The whole business of getting your medical is proving the net risk. In my case it was getting the doctors to see that my worst case scenario in the event of a problem I would be monocular, something that is allowable for airline pilots in many jurisdictions.
