Thank you bluesfan (chelsea?) for your words of encouragement!
I read up on the rules and regulations but i am not too sure if i understand it correctly. This is the statement from the licensing body where i come from (it is somewhat similar to the FAA & the CAA of UK).
"The function of the eyes and their adnexa shall be normal. There shall be no active pathological condition, acute or chronic, nor any sequelae of surgery or trauma of the eyes or their adnexa likely to reduce proper visual function to an extent that would interfere with the safe exercise of the applicant’s licence and rating privileges."
The eye specialist i saw had the view that keratoconus is an active pathological condition. He, along with 2 other eye specialists, also ruled me out from flying. However, he readily admits that he is no cornea specialist nor is he an expert on Keratonconus. In fact, he mentioned that he had only encountered about 20 keratoconus patients in his career and he is at least 60-70yrs of age! I think the next step for me would be to seek out an expert on Keratoconus and work with him to fight/argue my case like what you suggested.
A bit on my keratoconus: I think i started to develop it in my right eye when i was 17 but it was only detected when i was 23. I was immediately prescribed the Rigid Gas Permeable lens and my eyesight with it has always been correctable to 20/20, left eye still remains 20/20 unaided. I do not know if this means anything to you, but my myopia is 2.50, astig is 5.00 for the right eye. Three years have since passed and my keratoconus has not progressed any further.
So much has been mentioned on Keratoconus, but it is still a mystery as to what actually causes it. In my case, i used to rub my eyes a lot when i was younger. I would rub it till it went blood sore red! And i think that since i am a right hander, my right eye suffered the brunt of it.
So please tell your loved ones not to rub their eyes!
Thank you for stressing the part on finding an expert. I live in the tiny island of Singapore by the way, so i think i would have to extend my search further out.
